Ingredients explained

We don't have description for this ingredient yet.

Glycerin - superstar
Also-called: Glycerol | What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0
  • A natural moisturizer that’s also in our skin
  • A super common, safe, effective and cheap molecule used for more than 50 years
  • Not only a simple moisturizer but knows much more: keeps the skin lipids between our skin cells in a healthy (liquid crystal) state, protects against irritation, helps to restore barrier
  • Effective from as low as 3% with even more benefits for dry skin at higher concentrations up to 20-40%
  • High-glycerin moisturizers are awesome for treating severely dry skin
Read all the geeky details about Glycerin here >>

What-it-does: solvent

A clear, colorless liquid that works as a solvent and viscosity decreasing ingredient. It also has great skin-moisturizing abilities. 

Bifida Ferment Lysate is a probiotic ingredient that’s used in one of the most iconic serums in the world, the Estee Lauder Advanced Night Repair. Based on manufacturer info it potently protects against UV-induced damage in the skin and helps with DNA repair. An Estee Lauder patent from 2009 also talks about DNA repair activity.

As far as published research goes we could find one promising one. It showed that applying 10% bacterial extract to sensitive, reactive skin helped with better barrier function and decreased skin sensitivity

Also-called: Alphaflow | What-it-does: emollient, perfuming, solvent

A hydrocarbon-based emollient that can come in different viscosities from silky-light through satiny-smooth to luxurious, rich. It forms a non-occlusive film on the surface of the skin and brings gloss without greasiness to the formula. It's a very pure and hypoallergenic emollient that's also ideal for baby care products. 

What-it-does: emollient, solvent

A light-feeling, volatile (meaning it does not absorb into the skin but evaporates from it) silicone that gives skin a unique, silky and non-greasy feel. It has excellent spreading properties and leaves no oily residue or build-up. 

What-it-does: emollient

A super common emollient that makes your skin feel nice and smooth. It comes from coconut oil and glycerin, it’s light-textured, clear, odorless and non-greasy. It’s a nice ingredient that just feels good on the skin, is super well tolerated by every skin type and easy to formulate with. No wonder it’s popular. 

What-it-does: emollient

A clear, colorless, almost odorless oil that spreads nicely and easily and gives a velvet dry skin feel. It is good friends with sunscreen agents and helps to solubilize them. Also, it makes sunscreens feel lighter and spread easier. 

Also-called: Aqua | What-it-does: solvent

Good old water, aka H2O. The most common skincare ingredient of all. You can usually find it right in the very first spot of the ingredient list, meaning it’s the biggest thing out of all the stuff that makes up the product. 

It’s mainly a solvent for ingredients that do not like to dissolve in oils but rather in water. 

Niacinamide - superstar
Also-called: vitamin B3, nicotinamide | What-it-does: cell-communicating ingredient, skin brightening, anti-acne, moisturizer/humectant
  • A multi-functional skincare superstar with several proven benefits for the skin
  • Great anti-aging, wrinkle smoothing ingredient used at 4-5% concentration
  • Fades brown spots alone or in combination with amino sugar, acetyl glucosamine
  • Increases ceramide synthesis that results in a stronger, healthier skin barrier and better skin hydration
  • Can help to improve several skin conditions including acne, rosacea, and atopic dermatitis

What-it-does: emollient, emulsifying

We don't have description for this ingredient yet.

What-it-does: emollient, viscosity controlling, emulsifying, emulsion stabilising, surfactant/cleansing | Irritancy: 1 | Comedogenicity: 2

An extremely common multitasker ingredient that gives your skin a nice soft feel (emollient) and gives body to creams and lotions. It also helps to stabilize oil-water mixes (emulsions), though it does not function as an emulsifier in itself. Its typical use level in most cream type formulas is 2-3%.  

It’s a so-called fatty alcohol, a mix of cetyl and stearyl alcohol, other two emollient fatty alcohols.  Though chemically speaking, it is alcohol (as in, it has an -OH group in its molecule), its properties are totally different from the properties of low molecular weight or drying alcohols such as denat. alcohol. Fatty alcohols have a long oil-soluble (and thus emollient) tail part that makes them absolutely non-drying and non-irritating and are totally ok for the skin.

What-it-does: solvent

A really multi-functional helper ingredient that can do several things in a skincare product: it can bring a soft and pleasant feel to the formula, it can act as a humectant and emollient, it can be a solvent for some other ingredients (for example it can help to stabilize perfumes in watery products) and it can also help to disperse pigments more evenly in makeup products. And that is still not all: it can also boost the antimicrobial activity of preservatives

What-it-does: emulsifying | Irritancy: 2 | Comedogenicity: 3

An oily kind of ingredient that can magically blend with water all by itself. This is called self-emulsifying and SE in its name stands for that.

The difference between "normal" Glyceryl Stearate and this guy is that the SE grade contains a small amount of water-loving soap molecules, such as sodium stearate. This increases Glyceryl Stearate's affinity for water and gives it stronger emulsifying abilities.    

What-it-does: emollient

We don't have description for this ingredient yet.

What-it-does: emollient, viscosity controlling, emulsion stabilising | Irritancy: 2 | Comedogenicity: 2

A so-called fatty (the good, non-drying kind of) alcohol that does all kinds of things in a skincare product: it makes your skin feel smooth and nice (emollient), helps to thicken up products and also helps water and oil to blend (emulsifier). Can be derived from coconut or palm kernel oil.

Also-called: Shea Butter | What-it-does: emollient

Unless you live under a rock you must have heard about shea butter. It's probably the most hyped up natural butter in skincare today. It comes from the seeds of African Shea or Karite Trees and used as a magic moisturizer and emollient.

But it's not only a simple emollient, it regenerates and soothes the skin, protects it from external factors (such as UV rays or wind) and is also rich in antioxidants (among others vitamin A, E, F, quercetin and epigallocatechin gallate). If you are looking for rich emollient benefits + more, shea is hard to beat. 

Betaine - goodie
What-it-does: moisturizer/humectant

A sugar beet-derived amino acid derivative with nice skin protection and moisturization properties. Betaine's special thing is being an osmolyte, a molecule that helps to control cell-water balance.  It is also a natural osmoprotectant, meaning that it attracts water away from the protein surface and thus protects them from denaturation and increases their thermodynamic stability. 

It also gives sensorial benefits to the formula and when used in cleansers, it helps to make them milder and gentler. 

Also-called: Amur Cork Tree Bark Extract, Oubaku Ekisu | What-it-does: soothing, anti-acne

traditional East Asian medicine that has a couple of recent studies to back up its positive effects on the skin.

It seems to have potent anti-inflammatory activity, it's a mild antioxidant and also has strong anti-bacterial effect for acne causing bacteria, Propionibacterium acne. 

Also-called: Green Tea | What-it-does: antioxidant, soothing
  • Green tea is one of the most researched natural ingredients
  • The active parts are called polyphenols, or more precisely catechins (EGCG being the most abundant and most active catechin)
  • There can be huge quality differences between green tea extracts. The good ones contain 50-90% catechins (and often make the product brown and give it a distinctive smell)
  • Green tea is proven to be a great antioxidant, UV protectant, anti-inflammatory, anticarcinogenic and antimicrobial
  • Because of these awesome properties green tea is a great choice for anti-aging and also for skin diseases including rosacea, acne and atopic dermatitis

We don't have description for this ingredient yet.

Also-called: Gotu Kola, Tiger Grass | What-it-does: soothing, antioxidant, moisturizer/humectant

Centella Asiatica - or sometimes also called Gotu Kola or Cica - has been used in folk medicine for hundreds of years. It’s traditionally used to improve small wounds, burns and scratches and it’s also a well known anti-inflammatory agent for eczema.

Recently science has taken an interest in Gotu Kola as well and it turns out it really has many active compounds with several benefits. Just for hard-core geeks, the main biologically active compounds are pentacyclic triterpenoid saponins called asiaticoside, madecassoside, asiatic and madecassic acid (also called centellosides).

Also-called: Aloe Leaf Extract | What-it-does: soothing, emollient, moisturizer/humectant

The extract coming from the juice containing leaves of the Aloe vera plant. It's usually a hydroglycolic extract (though  oil extract for the lipid parts also exists) that has similar moisturizing, emollient and anti-inflammatory properties as the juice itself. We have written some more about aloe here.

We don't have description for this ingredient yet.

A biotechnologically derived ingredient that is produced by the fermentation of a marine bacteria living in the cold Antarctic Ocean. According to the manufacturer's info, it seems to have two different sets of magic properties: 

The first set includes skin-protecting and anti-aging abilities: it can help to protect the skin from dryness and redness due to cold weather and it also promotes skin regeneration and smoother skin surface by stimulating protein synthesis in the skin.  More specifically, these proteins are type I and IV collagen and elastin, all super important stuff for wrinkle-free, young looking skin (though these results came only from in-vitro tests and might or might not apply to living human skin).

Also-called: Guardiant, Glasswort Extract | What-it-does: antioxidant, skin brightening, moisturizer/humectant

A plant extract coming from glasswort, a type of succulent that grows in the salt marshes along the coastline of South Korea. According to its Korean manufacturer, it contains good-for-the-skin things like betaine, amino acids and minerals and the extract can strengthen the skin barrier, increase skin recovery and provide deep moisturization effect

There is also an in-vitro (not done on real people but in the lab) study from 2009 that shows promising antioxidant and skin whiting properties about the Salicornia Herbacea Extract and concludes that "it would be a good candidate for skin rejuvenating agent".

What-it-does: emollient, emulsifying

It's the chemically chopped up version of normal lecithin. Most often it's used to create liposomes and to coat and stabilize other ingredients. 

Also-called: Coconut Oil | What-it-does: emollient, perfuming | Irritancy: 0 | Comedogenicity: 4

There is definitely some craze going on for coconut oil both in the healthy eating space (often claimed to be the healthiest oil to cook with but this is a topic for another site) and in the skin and hair care space. 

We will talk here about the latter two and see why we might want to smear it all over ourselves. Chemically speaking, coconut oil has a unique fatty acid profile. Unlike many plant oils that mostly contain unsaturated fatty acids (fatty acids with double bonds and kinky structure such as linoleic or oleic), coconut oil is mostly saturated (fatty acids with single bonds only) and its most important fatty acid is Lauric Acid (about 50%).  Saturated fatty acids have a linear structure that can stack nice and tight and hence they are normally solid at room temperature. Coconut oil melts around 25 °C so it is solid in the tub but melts on contact with the skin. 

Also-called: Macadamia Oil | What-it-does: emollient

The golden yellow oil coming from the Macadamia nut, a native Australian nut. Similar to other plant oils, it's loaded with emollient and nourishing fatty acids. It's a high oleic acid oil (50-67% oleic acid and only 0-5% linoleic acid) that makes it very emollient and ideal for dry skin types (and less ideal for acne-prone skin).

Its unique property is that it contains high amounts of a rare fatty acid called palmitoleic acid (12-25%) that give Macadamia oil a "cushiony" feel. It's also easily absorbed and makes the skin soft and supple. 

What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0

It’s the - sodium form - cousin of the famous NMFhyaluronic acid (HA). If HA does not tell you anything we have a super detailed, geeky explanation about it here.  The TL; DR version of HA is that it's a huge polymer (big molecule from repeated subunits) found in the skin that acts as a sponge helping the skin to hold onto water, being plump and elastic. HA is famous for its crazy water holding capacity as it can bind up to 1000 times its own weight in water.

As far as skincare goes, sodium hyaluronate and hyaluronic acid are pretty much the same and the two names are used interchangeably. As cosmetic chemist kindofstephen writes on reddit  "sodium hyaluronate disassociates into hyaluronic acid molecule and a sodium atom in solution". 

What-it-does: moisturizer/humectant

Soluble Collagen refers to the big, natural collagen molecules mostly extracted from fish or bovine skin. Spotting collagen on the ingredient list, you might think that, aha, this must be there to supplement the collagen content of our own skin, but you have to know that collagen is a huge-huge molecule that cannot absorb to the middle layer of the skin where collagen is and even if it could, it cannot just magically go the right places to become part of the skin's own collagen network. Putting collagen on your skin for anti-aging purposes is like throwing tent poles onto a ramshackle tent and expecting the tent to magically become nice and firm again. 

The strong point of collagen is being a large molecule with tremendous water binding capacity, i.e. an amazing humectant and moisturizer. It produces a water-rich film on the skin giving the stratum corneum (the uppermost layer of the skin) great hydration, making it nice and smooth and reducing trans-epidermal-water loss (the process of water evaporating out of your skin).

Also-called: Rice Germ Oil | What-it-does: emollient

We don't have description for this ingredient yet.

Also-called: Jojoba Oil | What-it-does: emollient | Irritancy: 0 | Comedogenicity: 0-2

Jojoba is a drought resistant evergreen shrub native to South-western North America. It's known and grown for jojoba oil, the golden yellow liquid coming from the seeds (about 50% of the weight of the seeds will be oil).  

At first glance, it seems like your average emollient plant oil: it looks like an oil and it's nourishing and moisturizing to the skin but if we dig a bit deeper, it turns out that jojoba oil is really special and unique: technically - or rather chemically - it's not an oil but a wax ester (and calling it an oil is kind of sloppy). 

We don't have description for this ingredient yet.

Also-called: Part of Olivem 1000 | What-it-does: emulsifying

An ester that comes from Cetearyl alcohol and the fatty acids of olive oil. It often comes to the formula coupled with Sorbitan Olivate as the two together form the well-known, natural emulsifier trade named Olivem 1000. 

Other than helping oil and water to blend, the main thing of Olivem 1000 is generating liquid crystal structures that are similar to the lipid structures of the stratum corneum (the outermost layer of the skin). Thanks to this, Olivem 1000 doubles as an active ingredient with significant moisturizing, barrier-repairing and soothing properties.

Also-called: Part of Olivem 1000 | What-it-does: emulsifying

An ester coming from sorbitol and the fatty acids of olive oil. It is part of the popular emulsifier trade named Olivem 1000 that is well-known for generating biomimetic liquid crystal structures. We have more info on Olivem 1000 at Cetearyl Olivate >>

What-it-does: solvent

It's a type of glycol that - according to the manufacturer - is an extremely good replacement for other glycols like propylene or butylene glycol. Its main job is to be a solvent, but it has also very good antimicrobial properties and acts as a true preservative booster. Also helps with skin hydration without stickiness or tacky feel.

A glycerin-derived gentle cleansing agent that is described as being skin and eye-friendly, and not leaving the skin dry or tight. It's also used as a co-emulsifier or solubilizer that helps to blend small amounts of oily things into water-based products. 

What-it-does: viscosity controlling

A white, elastomeric silicone powder that gives a nice silky and powdery feel to the products. It also has some oil and sebum absorption capabilities. 

A helper ingredient that functions as a film-forming polymer (big molecule from repeated subunits).

It usually comes to the formula as part of a thickener-emulsifier trio paired with Polyisobutene and Polysorbate 20. The three togeather have excellent thickening properties with remarkable emulsifying-stabilising abilities. They also have a nice silicone feel with glide-on spreading. 

An amino acid-based emulsifier that helps water and oil to mix and stay that way. It is considered as natural, environmentally friendly, and hypoallergenic. 

A fatty alcohol (the non-drying type with a long oil loving chain of 22 carbon atoms) that is used to increase the viscosity of the formula and it also helps the oily and the watery parts to stay nicely mixed together (called emulsion stabilizing). 

What-it-does: emulsifying

A vegetable-based, PEG-free ingredient whose job is to help water and oil to mix nicely together (emulsifier). It is created by attaching ten water-loving glycerin molecules with the oil-loving fatty acid, stearic acid. The result is a partly water- and partly oil-loving molecule that creates stable and smooth emulsions that are also cosmetically elegant. It also has some moisturizing and softening benefits for skin and hair.

What-it-does: viscosity controlling

We don't have description for this ingredient yet.

What-it-does: moisturizer/humectant, solvent | Irritancy: 0 | Comedogenicity: 1

Butylene glycol, or let’s just call it BG, is a multi-tasking colorless, syrupy liquid. It’s a great pick for creating a nice feeling product.  

BG’s main job is usually to be a solvent for the other ingredients. Other tasks include helping the product to absorb faster and deeper into the skin (penetration enhancer), making the product spread nicely over the skin (slip agent), and attracting water (humectant) into the skin.

What-it-does: emollient, viscosity controlling | Irritancy: 2 | Comedogenicity: 1

A synthetic liquid oil that can replace mineral oil or silicone oils in the cosmetic formulas. There are different grades depending on the molecular weight ranging from very light, volatile, non-residue leaving ones to more substantial, slight residue leaving ones.

Apart from leaving the skin soft and smooth (emollient), it's also used as a waterproofing agent in sunscreens or makeup products and as a shine enhancer in lip gloss formulas. 

Allantoin - goodie
What-it-does: soothing | Irritancy: 0 | Comedogenicity: 0

Super common soothing ingredient. It can be found naturally in the roots & leaves of the comfrey plant, but more often than not what's in the cosmetic products is produced synthetically. 

It's not only soothing but it' also skin-softening and protecting and can promote wound healing.

What-it-does: emulsion stabilising

We don't have description for this ingredient yet.

Panthenol - goodie
Also-called: Pro-Vitamin B5 | What-it-does: soothing, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0

An easy-to-formulate, commonly used, nice to have ingredient that’s also called pro-vitamin B5. As you might guess from the “pro” part, it’s a precursor to vitamin B5 (whose fancy name is pantothenic acid). 

Its main job in skincare products is to moisturise the skin. It’s a humectant meaning that it can help the skin to attract water and then hold onto it. There is also research showing that panthenol can help our skin to produce more lovely lipids that are important for a strong and healthy skin barrier. 

What-it-does: moisturizer/humectant

We don't have description for this ingredient yet.

It's one of the most commonly used thickeners and emulsion stabilizers. If the product is too runny, a little xanthan gum will make it more gel-like. Used alone, it can make the formula sticky and it is a good team player so it is usually combined with other thickeners and so-called rheology modifiers (helper ingredients that adjust the flow and thus the feel of the formula). The typical use level of Xantha Gum is below 1%, it is usually in the 0.1-0.5% range. 

Btw, Xanthan gum is all natural, a chain of sugar molecules (polysaccharide) produced from individual sugar molecules (glucose and sucrose) via fermentation. It’s approved by Ecocert and also used in the food industry (E415). 

Adenosine - goodie

Adenosine is an important little compound in our body that has a vital cell-signalling role. Research on smearing it on our face is also promising and shows so far a couple of things:

  • It can help with wound healing
  • It’s a good anti-inflammatory agent
  • It might even help with skin’s own collagen production and improve skin firmness and elasticity
  • It helps with barrier repair and protection
  • It might be even useful for the hair helping with hair thickness and hair growth
Raffinose - goodie
What-it-does: moisturizer/humectant

It's a so-called trisaccharide (consists of three monosaccharides: glucose, fructose, and galactose) that - similar to other sugar-type ingredients - works as a water-binding, moisturizer ingredient on the skin. 

Cholesterol - goodie
What-it-does: skin-identical ingredient, emollient | Irritancy: 0 | Comedogenicity: 0

It's one of the important lipids that can be found naturally in the outer layer of the skin. About 25% of the goopy stuff between our skin cells consists of cholesterol. Together with ceramides and fatty acids, they play a vital role in having a healthy skin barrier and keeping the skin hydrated. 

Apart from being an important skin-identical ingredient, it's also an emollient and stabilizer

What-it-does: emollient | Irritancy: 0 | Comedogenicity: 2-4

A super common, medium-spreading emollient ester that gives richness to the formula and a mild feel during rubout. It can be a replacement for mineral oil and is often combined with other emollients to achieve different sensorial properties.

What-it-does: chelating

Super common little helper ingredient that helps products to remain nice and stable for a longer time. It does so by neutralizing the metal ions in the formula (that usually get into there from water) that would otherwise cause some not so nice changes.

It is typically used in tiny amounts, around 0.1% or less.

What-it-does: antioxidant

We don't have description for this ingredient yet.

What-it-does: emulsifying | Irritancy: 0 | Comedogenicity: 1-2

A handy helper ingredient that helps water and oil to mix nicely together, aka emulsifier. It is especially recommended for protective, baby care and general purpose emollient creams. 

It also helps to disperse insoluble particles (think color pigments or zinc/titanium dioxide sunscreen) nice and even in cosmetic formulas. 

Lecithin - goodie
What-it-does: emollient, emulsifying

A very common ingredient that can be found in all cell membranes. In cosmetics it's quite the multi-tasker: it's an emollient and water-binding ingredient but it's also an emulsifier and can be used for stabilization purposes. It's also often used to create liposomes

Also-called: Zemea | What-it-does: solvent, moisturizer/humectant

Propanediol is a natural alternative for the often used and often bad-mouthed propylene glycol. It's produced sustainably from corn sugar and it's Ecocert approved. 

It's quite a multi-tasker: can be used to improve skin moisturization, as a solvent, to boost preservative efficacy or to influence the sensory properties of the end formula. 

Ceramide NP - goodie
Also-called: Ceramide 3 | What-it-does: skin-identical ingredient

One of the many types of ceramides that can be found naturally in the upper layer of the skin. Ceramides make up about 50% of the goopy stuff that's between our skin cells and play a super important role in having a healthy skin barrier and keeping the skin hydrated. It works even better when combined with its pal, Ceramide 1.

We wrote way more about ceramides at ceramide 1, so click here to know more.

What-it-does: moisturizer/humectant

A biocompatible copolymer (a big molecule that consists of more than one type of building blocks) that has the same structure as important cell membrane ingredient, phospholipid. Polyquaternium-51 is a good skin moisturizer, leaves a silky, smooth feel on the skin and can help to reduce irritation caused by some not-so-nice ingredients (like surfactants).

We don't have description for this ingredient yet.

polymeric (big molecule from repeated subunits) emulsifier that comes from Inulin, a naturally occurring polysaccharide found in the roots and rhizomes of several plants. The emulsifier is obtained by adding oil-loving chains onto inulin. The resulting copolymer can emulsify high amounts of oil and can stabilize oil droplets or non-water soluble particles so that they do not clump together in the formula. 

Lauric Acid - goodie
What-it-does: anti-acne, surfactant/cleansing, emulsifying | Irritancy: 1 | Comedogenicity: 4

A 12 carbon length fatty acid that can be found naturally in coconut milk, coconut oil, laurel oil, and palm kernel oil. It's also in breast milk. As a skincare ingredient, it can be used as an emulsifier or as a cleansing agent.

What's more, there is emerging research about lauric acid being a good anti-acne ingredient.  A 2009 study found that the lowest concentration to prevent evil acne-causing P. acnes growth of lauric acid is over 15 times lower than that of gold standard anti-acne ingredient benzoyl peroxide.

We don't have description for this ingredient yet.

What-it-does: buffering

It's a little helper ingredient that helps to set the pH of the products to be right. It has an alkaline pH and can neutralize acidic ingredients.

A white to beige powder that is described as the golden standard emulsifier for emulsions (oil+water mixtures) that are difficult to stabilize. It is especially popular in sunscreens as it can boost SPF protection and increase the water-resistance of the formula. 

We don't have description for this ingredient yet.

The chemically chopped up version of the big protein molecule, collagen. It is often derived from fish or bovine sources and works as a nice moisturizer and humectant that helps the skin to hold onto water.  

To understand a bit more what Hydrolyzed Collagen is, you have to know that proteins are large chains of amino acids connected with so-called peptide bonds. These bonds can be broken up when a water molecule is added and the resulting thing is a mix of shorter length amino acids, also called peptides. So Hydrolyzed Collagen is not really collagen, it is rather an undefined and varying mix of largish peptides. Based on a manufacturer's data, the whole, soluble collagen has an average molecular weight of 300 000 Da, while this chopped up mixture has an average MW of 12 000 Da (still pretty big). 

This is a trade name with the following INCI listing: Water, Collagen

This ingredient name is not according to the INCI-standard. :( What, why?!

Also-called: Aqua | What-it-does: solvent

Good old water, aka H2O. The most common skincare ingredient of all. You can usually find it right in the very first spot of the ingredient list, meaning it’s the biggest thing out of all the stuff that makes up the product. 

It’s mainly a solvent for ingredients that do not like to dissolve in oils but rather in water. 

Collagen - goodie
What-it-does: moisturizer/humectant

The big and important protein molecule that usually comes from animal skin such as fish or bovine. The gist of the "collagen in topical skincare" subject is to know that collagen in a jar has nothing to do with wrinkles but everything to do with skin hydration. We have a shiny explanation about this at soluble collagen, so click here to read more >> 

Also-called: Vitamin E Acetate | What-it-does: antioxidant | Irritancy: 0 | Comedogenicity: 0

It’s the most commonly used version of pure vitamin E in cosmetics. You can read all about the pure form here. This one is the so-called esterified version. 

According to famous dermatologist, Leslie Baumann while tocopheryl acetate is more stable and has a longer shelf life, it’s also more poorly absorbed by the skin and may not have the same awesome photoprotective effects as pure Vit E. 

Biosaccharide Gum-1 is a pretty interesting kind of sugar ingredient that is created from sorbitol via bacterial fermentation. 

According to the manufacturer it’s a “S.M.A.R.T.” sugar: it has Soothing, Moisturizing, Anti-aging, Restructuring and Touch properties. Let’s look at them quickly one by one.

What-it-does: moisturizer/humectant

The main part of a moisturizing complex called Aquaxyl. Comes from two water-binding plant sugars, glucose and xylitol. According to the manufacturer, Aquaxyl is close to a magic moisturizer that not only simply moisturizes, but can "harmonize the skin's hydrous flow".

This means that on the one side it can optimize water reserves by increasing important NMFs (natural moisturizing factors - things that are naturally in the skin and help to keep it hydrated) - like hyaluronic acid and chondroitin sulfate -  in the skin. On the other side, it also limits water loss by improving the skin barrier with increased lipid (ceramides and cholesterol) and protein synthesis. 

What-it-does: moisturizer/humectant

We don't have description for this ingredient yet.

What-it-does: moisturizer/humectant

A sugar derived moisturizer that's part of a moisturizing trio called Aquaxyl. You can read more about its magic properties at xylitylglucoside

Xylitol - goodie
What-it-does: moisturizer/humectant

A type of sugar that's part of a moisturizing trio called Aquaxyl. You can read more about its magic properties at xylitylglucoside

What-it-does: surfactant/cleansing

We don't have description for this ingredient yet.

What-it-does: emollient, emulsifying, surfactant/cleansing | Irritancy: 0 | Comedogenicity: 2

A liquid emollient derived from isostearic acid that gives a rich, cushiony skin-feel and unusually high levels of gloss. It also has film-forming abilities but without leaving a sticky residue and it aids long-lasting and water-resistant properties. All this makes Pentaerythrityl Tetraisostearate an ideal emollient for long-lasting protective emulsions, like lip balms.

We don't have description for this ingredient yet.

What-it-does: emulsifying | Irritancy: 1-2 | Comedogenicity: 1-2

An ingredient that helps water and oil to mix together, aka emulsifier. Chemically speaking, it comes from the attachment of sorbitan (a dehydrated sorbitol (sugar) molecule) with the fatty acid Lauric Acid, that creates a partly water (the sorbitan part) and partly oil soluble (lauric part) molecule. 

Sorbitan Laurate is a good team player that likes to work with many other emulsifiers and is compatible with a wide range of other ingredients.

Glucose - goodie
What-it-does: moisturizer/humectant

A fancy name for sugar. Luckily when you put it on your skin it's good for you not like when you eat it. :) It has water-binding properties, which means that it helps to keep your skin nice and hydrated

We don't have description for this ingredient yet.

What-it-does: surfactant/cleansing

What-it-does: surfactant/cleansing

We don't have description for this ingredient yet.

It's a little helper ingredient coming from corn, rice or potato starch that can help to keep skin mat (absorbent), to stabilise emulsions, and to keep the product together (binding). 

What-it-does: solvent, emulsifying, perfuming, surfactant/cleansing | Irritancy: 0-1 | Comedogenicity: 0-2

Similar to other glycols, it's a helper ingredient used as a solvent, or to thin out thick formulas and make them more nicely spreadable. 

Hexylene Glycol is also part a preservative blend named Lexgard® HPO, where it helps the effectiveness of current IT-preservative, phenoxyethanol

Squalane - goodie
What-it-does: skin-identical ingredient, emollient | Irritancy: 0 | Comedogenicity: 1

It seems to us that squalane is in fashion and there is a reason for it. Chemically speaking, it is a saturated  (no double bonds) hydrocarbon (a molecule consisting only of carbon and hydrogen), meaning that it's a nice and stable oily liquid with a long shelf life. 

It occurs naturally in certain fish and plant oils (e.g. olive), and in the sebum (the oily stuff our skin produces) of the human skin. As f.c. puts it in his awesome blog post, squalane's main things are "emolliency, surface occlusion, and TEWL prevention all with extreme cosmetic elegance". In other words, it's a superb moisturizer that makes your skin nice and smooth, without being heavy or greasy.

We don't have description for this ingredient yet.

Also-called: HEC | What-it-does: viscosity controlling, emulsion stabilising

A nice little helper ingredient that can thicken up cosmetic products and create beautiful gel formulas. It's derived from cellulose, the major component of the cell wall of green plants. It is compatible with most co-ingredients and gives a very good slip to the formulas. 

We don't have description for this ingredient yet.

Collagen - goodie
What-it-does: moisturizer/humectant

The big and important protein molecule that usually comes from animal skin such as fish or bovine. The gist of the "collagen in topical skincare" subject is to know that collagen in a jar has nothing to do with wrinkles but everything to do with skin hydration. We have a shiny explanation about this at soluble collagen, so click here to read more >> 

Also-called: Form of Vitamin C, 3-O-Ethyl Ascorbate, EAC;Ethyl Ascorbic Acid | What-it-does: antioxidant, skin brightening

A very stable and promising form of the skincare superstar, Vitamin C. If you do not know why Vitamin C is such a big deal in skin care, you can catch up here. In short, Vitamin C has three proven magic abilities: antioxidant, collagen booster, and skin brightener. The problem, though, is that it's very unstable, turns brown and becomes ineffective in no time (after a few month) and the cosmetics industry is trying to come up with smart derivatives that are stable and have the magic properties of pure Vitamin C. 

Ethyl Ascorbic Acid or EAC for short is an "etherified derivative of ascorbic acid" that consists of vitamin C and an ethyl group bound to the third carbon position. This makes Vitamin C very stable and soluble in both water and oil.

What-it-does: antioxidant

We don't have description for this ingredient yet.

Amino acids are important natural moisturizing factors (NMFs), that can be found naturally in the skin where they help the epidermis (upper layer of the skin) to stay nice and hydrated

Amino acids are also the building blocks of proteins, such as collagen, so when you thoroughly chop up a big collagen molecule, you end up with an amino acid mixture, like this guy we are writing about. Btw, if you chop it up less thoroughly, you get hydrolyzed collagen, a kind of peptide mixture with smallish chains of amino acids. 

Mannitol - goodie
What-it-does: moisturizer/humectant

A type of sugar molecule, that has water-binding properties and helps to keep your skin hydrated

Lactic Acid - superstar
  • It’s the second most researched AHA after glycolic acid
  • It gently lifts off dead skin cells to reveal newer, fresher, smoother skin
  • It also has amazing skin hydrating properties
  • In higher concentration (10% and up) it improves skin firmness, thickness and wrinkles
  • Choose a product where you know the concentration and pH value because these two greatly influence effectiveness
  • Don’t forget to use your sunscreen (in any case but especially so next to an AHA product)
Read all the geeky details about Lactic Acid here >>

Sarcosine - goodie

We don't have description for this ingredient yet.

Also-called: Calmosensine | What-it-does: cell-communicating ingredient, soothing

 A soothing dipeptide (tyrosine + arginine) based molecule that functions as a "messenger of tranquility and muscle relaxation". It works via stimulating the skin nerve cells to release met-enkephalin, which is an opioid (i.e. relaxing, pain-relieving) messenger molecule. 

This means that Acetyl Dipeptide-1 Cetyl Ester can "signal" our skin cells to "relax" and it can instantly decrease skin irritations coming from heat, chemical stinging or mechanical stresses. It is also claimed to be able to prevent the onset of wrinkles and expression lines thanks to its muscle relaxation properties.

What-it-does: moisturizer/humectant

We don't have description for this ingredient yet.

We don't have description for this ingredient yet.

A cellulose-derived helper ingredient that is created by attaching a water-hating part (cetyl group) to the water-loving thickener, Hydroxyethylcellulose. The resulting thing, Cetyl Hydroxyethylcellulose is also a thickener but with some surface active properties (as part of the molecule is water-loving and part of it is oil loving). Thanks to its surface-active properties, it also works as an emulsion stabilizer

Also-called: Syn-Ake | What-it-does: cell-communicating ingredient

This awfully long named ingredient is, in fact, a pretty small molecule. It's a tripeptide (a three amino acid peptide)  with molecular weight less than 500 Da, meaning that it's small enough to penetrate nicely and easily into the skin.

It belongs to the "Botox in a jar" type of peptides (similar to Argireline or Leuphasyl) targeting wrinkles caused by facial movements, like laughter lines or crow’s feet. According to the manufacturer's in-vivo (made on real people) studies, 4% Syn-Ake used for 28 days resulted in 21% smoother and 15-20% less wrinkled skin with max values up to 52%. The smoothing effect was measurable on 80% of the volunteers, while the wrinkle reduction effect was evident on 73%.

Rutin - goodie
What-it-does: antioxidant

Rutin is a polyphenol flavonoid found in many plants, for example, citrus fruits. The main reason it's used in cosmetics is its high antioxidant and free radical-scavenging ability (similar to that of superstar ascorbic acid), but also has some antibacterial nature and wound-healing properties.

There is also an in-vitro (made in Petri dishes on animal cell lines) study showing potential for rutin as a skin-whitening agent and people have even tried using it to increase the UV-blocking ability of SPF agents, but with inconsistent results. Either way, its antioxidant abilities should still help protect the skin against sun damage from the UV light that isn’t blocked by SPF agents!

It's a water-hating, fumed silica that works as a thickener for oils and it can also suspend particles in oils.

Also, increases the gloss of castor oil that can be useful for makeup products.

What-it-does: soothing, preservative

Lactobacillus ferment is an interesting probiotic ingredient with some promising properties. 

First, according to a 2009 Estee Lauder patent, it’s a DNA repair enzyme and it can help to protect the skin against environmental aggressors.

What-it-does: moisturizer/humectant

We don't have description for this ingredient yet.

What-it-does: moisturizer/humectant

Hydrolyzed Hyaluronic Acid is a low molecular weight, chemically chopped up version of the naturally big molecule and current IT-moisturizer, Hyaluronic Acid (HA). The TL; DR version of HA is that it's a huge polymer (big molecule from repeated subunits) found in the skin that acts as a sponge helping the skin to retain water, making it plump and elastic. As HA is a polymer, the subunits can be repeated many times (as a high-molecular-weight version), or just a few times (as a low-molecular-weight version).

We wrote in detail at HA about how different molecular weight versions do different things both as a component of the skin and as a skincare ingredient, so click here and read about all the details. Hydrolyzed Hyaluronic Acid can also come in different molecular-weight versions with different properties:

Also-called: miniHA | What-it-does: moisturizer/humectant

It's a super small, chemically chopped up version of sodium hyaluronate. Its trade name is miniHA, and its molecular weight is 10 kDa. This counts as really tiny given that "normal" HA has a molecular weight of 0.5-2 million Da.

To be honest, low molecular weight (LMW), and especially this ultra-low molecular weight HA is a controversial ingredient. On the upside, it can penetrate the skin better (though 10kDa still counts as big!) and might be able to moisturize the deeper layers of the skin where normal HA cannot get. Also, according to the manufacturer of miniHA, it has better antioxidant activity than a 1.6MDa version HA and it also has better sun protection and after-sun repair abilities than the higher MW versions. It also works in synergy with higher molecular weight versions, and the combination of 0.1% 1.45MDa-HA + 0.1% 380 kDa-HA + 0.1% miniHA hydrated the skin significantly better than 0.3% 1.45MDa-HA alone.

Alanine - goodie

A non-essential amino acid (a building block of skin proteins like collagen or elastin) that hydrates the skin.

Arginine - goodie

A semi-essential (infants cannot synthesize it, but adults can) amino acid that is one of the primary building blocks of hair keratin and skin collagen. It's a natural moisturizing factor, a skin hydrator and might also help to speed up wound healing

Arginine usually has a positive charge (cationic) that makes it substantive to skin and hair (those are more negatively charged surfaces) and an excellent film former.  Thanks to the positive charge, it also creates a complex with AHAs (AHAs like to lose a hydrogen ion and be negatively charged, so the positive and the negative ions attract each other) that causes a "time-release AHA effect" and reduces the irritation associated with AHAs

We don't have description for this ingredient yet.

Aspartic Acid - goodie

A non-essential amino acid  (important building block of collagen and elastin) that hydrates the skin. It is also used to set the pH of the cosmetic product (buffering).

What-it-does: moisturizer/humectant

Glutamic acid is a little molecule and non-essential (our body can synthesize it) amino acid with the important job of being a neurotransmitter in the human body meaning that it helps your nervous system work correctly. 

As for what it's doing in cosmetics, Glutamic acids' main thing (similar to other amino acids) is being a humectant moisturizer and skin-conditioning agent (sidenote: if you attach lots of glutamic acid molecules, you get polyglutamic acid that is claimed to be a better than hyaluronic acid humectant). It also seems to affect skin barrier repair, however, it is not clear-cut in which direction.

We don't have description for this ingredient yet.

Glycine - goodie

A non-essential amino acid (the building blocks of skin proteins, like collagen or elastin), that the body can produce itself, but its production decreases with age. When you put it all over your face, it works as a moisturizer and maybe more. 

According to great skincare blog Futurederm, glycine might help with wound healing and tissue repair and when used together with other amino acids, leucine and proline it might improve wrinkles

Histidine - goodie

A semi-essential amino acid meaning that enough has to be eaten from it so that the body does not use up essential amino acids (that our body cannot produce itself) to synthesize it. It has an important role in regulating the immune defense, allergic reactions, and inflammatory processes in the body.

As for skincare, it's a skin moisturizer that might also protect from some skin infections

Isoleucine - goodie

A branch-chained, essential amino acid that can be found in things like almond, cashew or soy protein. When taken orally it may promote protein synthesis. As for skincare - like all the amino acids - it's a skin-identical ingredient and moisturizer. It also seems to be useful as a barrier repair ingredient.

Ornithine - goodie
Also-called: Adipofill'In | What-it-does: cell-communicating ingredient

Ornithine is an amino acid that is the active ingredient in the skin-plumping active trade named Adipofill'In. According to the manufacturer, Adipofill'In is able to increase fatty tissue volume by activating the transcription factor called HIF-1α and thus it has a lipofilling-like effect through a non-invasive method.

It is supposed to be an especially useful active for deep wrinkles, such as the nasolabial fold (the wrinkle between the nose and mouth). In their in-vivo test made with 20 volunteers using 2% Adipofill'In cream twice a day for 60 days, the manufacturer measured up to 37.6% reduction of wrinkle depth and up to 27.5% reduction of skin roughness.

Phenylalanine - goodie

An essential amino acid that the body cannot produce itself but has to take from the diet. Combined with UVA exposure, phenylalanine is used in the treatment of vitiligo (a pigmentation disorder where patches of the skin lose the pigment).

Proline - goodie

A non-essential amino acid (meaning that our body can produce it) that's also one of the major building blocks of collagen. According to the Futurederm blog, it might be able to improve wrinkles when combined with other amino acids, glycine and leucine

Serine - goodie

Serine is an amino acid that most often comes to the formula as part of a moisturizing complex. It's a non-essential amino acid (meaning that our body can synthesize it) and serves as a water-binding ingredient.

In general, amino acids are great skincare ingredients that play an important role in proper skin hydration but there is not much info out there about what specifically serine can do for the skin.

Threonine - goodie

An essential amino acid that's also a key building block of collagen and elastin. When taken orally, it helps the digestive and intestinal tracts function more smoothly and also helps the absorption of nutrients. As for skincare, it is not clear what it does other than being a skin hydrator

Valine - goodie

An essential amino acid (a building block of skin proteins like collagen) that our body cannot produce itself but has to take from external sources, like diet. 

It's a branched chain amino acid that is claimed to enhance energy, increase endurance and aid in muscle tissue recovery and repair when taken as a supplement. It's not clear what valine does when you put it on the skin, but as all amino acids, it must be at least a great skin hydrator.

Also-called: Syn-Coll | What-it-does: cell-communicating ingredient

A tripeptide (three amino acids attached to each other: Lys-Val-Lys) that's claimed to protect and boost collagen and improve skin texture.

The manufacturer did an in-vivo (made on real people) study with 45 volunteers and found that used twice daily for 84 days 1% and 2.5% Syn-Coll reduces the appearance of wrinkles by 7 and 12% respectively. In another study (also by the manufacturer) with 33 female Chinese volunteers, 77% of the participants felt that Syn-Coll visibly improved the firmness and elasticity of the skin after 4 weeks. What's more, 60% of the participants also noticed a reduction in the look of the pore size also after 4 weeks of treatment.

What-it-does: buffering

We don't have description for this ingredient yet.

  • It’s naturally in our skin and behaves there like a sponge
  • It can bind up to 1000 times its own weight in water
  • It is a big molecule from repeated subunits (polymer) so different molecular weight versions exist (unfortunately there is no way to determine MW from INCI list only)
  • High-molecular-weight-HA (>500 kDa) is an excellent surface hydrator, skin protectant and can act as an osmotic pump helping water-soluble actives to penetrate deeper into the skin
  • Low-molecular-weight-HA (< 500 kDa) can hydrate the skin somewhat deeper though it is still a big molecule and works mainly in the epidermis (outer layer of the skin)
  • Low-molecular-weight-HA might also help the skin to repair itself by increasing its self-defense (~ 200kDa used in the study)
  • Ultra-low-molecular-weight-HA (<50kDa) is a controversial ingredient and might work as a pro-inflammatory signal molecule

We don't have description for this ingredient yet.

It's a special "cross-linked" from of IT-moisturizer, hyaluronic acid (HA). Cross-linked means that "normal" HA pieces (1-2 million Da molecular weight) are chemically bound togeather to create a big, "infinite" mesh.

The special HA mesh has a remarkable water-binding capacity, 5 times more than the already crazy water-binding capacity of "normal" HA. This water filled crosslinked HA gel forms a smooth film on the skin and continuously delivers the bound water, so it gives long-term moisturizing benefits.

Also-called: Argireline, Acetyl Hexapeptide-3 | What-it-does: cell-communicating ingredient, moisturizer/humectant

If you see a cosmetic product that claims that it has "Botox-like effect" then two things are almost certain: one, the product overpromises and two, it contains Argireline. 

So this one is the famous peptide that's marketed by its manufacturer as the "Botox in a jar". The basis for this claim is that it targets the same wrinkle forming mechanism (wrinkles caused by facial muscle movement) as Botox, but the way it works is very different. In addition, the extent to which it can prevent muscles from contracting (and to smooth wrinkles) is very different (otherwise why would anyone use still Botox?). 

Gluconolactone - superstar
What-it-does: exfoliant, chelating
  • It’s a polyhydroxy acid (PHA), that is often referred to as next generation AHA
  • It gently lifts off dead skin cells form the skin surface making skin smooth and even
  • In the long term it provides anti-aging benefits, like increased skin thickness and decreased wrinkles (though a tad less than even more proven superstar AHAs)
  • It’s a great moisturizer and even helps to repair impaired skin barrier
  • It’s antioxidant, and does not make your skin more sensitive to the sun
  • It can be used even if your skin is very sensitive, rosacea prone or if you are post cosmetic procedure

What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0

Though its name does not reveal it, this molecule is a relative of famous IT-moisturizer, Hyaluronic Acid. Just like HA, it is a glycosaminoglycan (aka GAG), meaning that it is a big sugar molecule from repeated subunits (what's more, one of the subunits is the same, glucuronic acid). Along with HA and other GAGs, it likes to hang out in the dermis (middle) layer of the skin where it is part of the gooey, bouncy stuff outside of the cells called extracellular matrix (ECM). 

As for skincare, Sodium Chondroitin Sulfate is probably too big to go right into the dermis (though much smaller than HA with 5000-50 000 Da molecular weight), but it has a comparable water binding ability to HA (which means a crazy water binding ability) and better affinity for the skin surface. This means that it forms a nice, water-rich film on the skin bringing an immediate and strong moisturising effect. 

What-it-does: skin-identical ingredient, emollient, emulsifying | Irritancy: 0 | Comedogenicity: 2

A fatty acid that can be found naturally in the skin. In fact, it's the most common saturated fatty acid found in animals and plants.

As for skincare, it can make the skin feel nice and smooth in moisturizers (emollient) or it can act as a foam building cleansing agent in cleansers. It's also a very popular ingredient in shaving foams.

What-it-does: moisturizer/humectant

We don't have description for this ingredient yet.

What-it-does: emollient, viscosity controlling | Irritancy: 0 | Comedogenicity: 2-3

A common multi-tasker fatty acid. It makes your skin feel nice and smooth (emollient), gives body to cream type products and helps to stabilize water and oil mixes (aka emulsions).

What-it-does: moisturizer/humectant

Sodium Acetylated Hyaluronate is a variation of current IT moisturizer, Hyaluronic acid, where some water-loving -OH groups are replaced by amphipathic (partly water-loving and partly water-hating) acetyl groups. The modified molecule is claimed to have even better moisture retention ability than normal HA and better affinity to the skin surface. 

The better affinity comes from the acetyl groups that act as tiny "anchors" to attach the HA molecule to the skin. Staying on top of the skin better and longer means longer-lasting surface hydration and improved elasticity. It is also less sticky and more cosmetically elegant than normal HA, so no wonder the nickname of this molecule is super hyaluronic acid.

Also-called: Part of Matrixyl 3000, Pal-GQPR, Previously Palmitoyl Tetrapeptide-3 | What-it-does: cell-communicating ingredient

A four amino acid peptide with the amino sequence of glycine-glutamine-proline-arginine. It is attached to palmitic acid (a fatty acid)  to increase oil solubility and skin penetration. 

It works by reducing the production of the signal moleculeinterleukin-6 (IL-6) which promotes inflammation in the skin and less inflammation means slower degradation of important things (like collagen) that results in younger looking skin for a longer time. 

Also-called: Part of Matrixyl 3000, Pal-GHK, Formerly also Palmitoyl Oligopeptide | What-it-does: cell-communicating ingredient

A really famous peptide that is part of Matrixyl 3000, the most sold peptide complex in the word. Before we go and find out what the big deal with Matrixyl 3000 is, let's just focus on Palmitoyl Tripeptide-1 itself for a bit.

It's a small three amino acid (they are the building blocks of all proteins) peptide with the amino sequence of glycine-histidine-lysine, or GHK. GHK is attached to palmitic acid (a fatty acid) to increase oil solubility and skin penetration.

Also-called: Form of Vitamin C, SAP | What-it-does: antioxidant, anti-acne

The sodium salt form of skincare superstar, vitamin C. If you do not know what the big fuss about vitamin C is, you are missing out and you have to click here and read all the geeky details about it.

Pure vitamin C (aka ascorbic acid, AA) is great and all, but its lack of stability is a big challenge for the cosmetics industry. One solution is to create stable derivatives that can be absorbed into the skin, convert there to AA and do all the magic AA is proven to do (which is being an antioxidant, a collagen booster, and a skin brightener).

Also-called: Form of Vitamin C, MAP | What-it-does: skin brightening, antioxidant

A form of skincare superstar, Vitamin C. If you do not know, what the big deal about Vitamin C is, click here and read all about it, we will wait here for you. 

So now you know that pure vitamin C (aka ascorbic acid, AA) is really unstable and hard to formulate so the cosmetics industry is coming up with a bunch of derivatives to solve the problem and Magnesium Ascorbyl Phosphate (or MAP) is one of them.  

Also-called: SNAP-8, Acetyl Glutamyl Heptapeptide-1 | What-it-does: cell-communicating ingredient, moisturizer/humectant

A newer and, molecule-wise, somewhat bigger version of the famous "Botox-like" peptide called Acetyl Hexapeptide-8 or Argireline. Just like Argireline, Acetyl Octapeptide-3 is also claimed to influence the muscle contraction process that results in a more relaxed and line-free face, especially around the forehead and the eyes.  

While Argireline counts as a pretty well-proven peptide, with multiple studies confirming its anti-wrinkle efficacy, we cannot say the same for Acetyl Octapeptide-3. What we have is the manufacturer's claim that comparing 10% Argireline with 10% SNAP-8 solution (that means 0.005% pure peptide powder) the SNAP-8 peptide did a bit better as it reduced wrinkles by 34.98% vs 27.05% reduction for Argireline (twice a day use for 28 days on 17 women).

Dipeptide-2 - goodie
Also-called: Part of Eyeliss | What-it-does: cell-communicating ingredient

A tiny peptide with only two amino acids (amino acids are the building block of proteins, and peptides are a few amino acids attached together), Valine and Tryptophan. It's part of a 3 actives complex called Eyeliss (with HMC and Palmitoyl Tetrapeptide-7) that's supposed to fight under-eye bags

The manufacturer claims that this dipeptide in Eyeliss can increase lymphatic circulation and the three actives together represent a "global approach to treating puffy eyes". The clinical study of the manufacturer with 20 people and 3% Eyeliss showed improvement after 56 days for 70% of the participants.

Also-called: GHK-Cu, Copper Peptide | What-it-does: cell-communicating ingredient, soothing, antioxidant
  • GHK-Cu is a copper-peptide complex found naturally in yucky bodily fluids (plasma, saliva, and urine)
  • It has unique wound healing properties by stimulating the breakdown of unhealthy, too large collagen in scar tissue and stimulating nice and healthy collagen production afterwards
  • It stimulates the production of several important skin-identical ingredients (e.g. collagen, elastin, and glycosaminoglycans)
  • It has significant anti-inflammatory and antioxidant effect
  • There are a few promising studies showing GHK-Cu can improve skin elasticity, clarity, firmness and reduce lines and wrinkles
  • It can improve hair growth by enlarging hair follicles (and bigger follicles produce longer, thicker hair)
  • There are some urban legends about possible overdosing or facial hair problems (read more in geeky details)
Read all the geeky details about Copper Tripeptide-1 here >>

A relatively new, four amino acid peptide that promises to help combat hair loss alongside red clover extract as part of the trademarked technology Capixyl

The main thing of  Acetyl Tetrapeptide-3 is to stimulate the synthesis of key Extra Cellular Matrix (aka ECM, the gooey stuff between cells that make up the framework of our skin) components in the scalp.  According to the manufacturer’s lab studies, the expression of type III collagen increased by 65% and the expression of laminins (anchoring proteins found in the ECM) was up a massive 285%, resulting in a stronger ECM bed for hair anchoring.

Also-called: Thymulen 4 | What-it-does: cell-communicating ingredient

A four amino acid peptide that is claimed to mimic the youth hormone called thymopoietin. It works by compensating the loss of thymic factors that come with age and is thought to stimulate the skin immune defenses and to help the skin regenerate

Also-called: EYESERYL | What-it-does: cell-communicating ingredient, moisturizer/humectant

A four amino acid peptide that is claimed to improve puffy eye bags via its anti-oedema and anti-glycation effects.

To back this claim up, the manufacturer created an in-vivo study with 20 volunteers using 10% of EYESERYL (that comes down to 0.01% (!) of the pure peptide) and found that by day 15, 70% of the volunteers improved, while 95% of the volunteers improved by the end of the study (60 days). About third of them improved only slightly, third of them showed an ok improvement and third showed a good improvement. They also have pretty convincing before and after photos, so we can tell you that for the lucky ones, the improvement can be real and visible.

Tripeptide-1 - goodie
Also-called: GHK, Kollaren | What-it-does: cell-communicating ingredient

A small, three amino acid (glycine-histidine-lysine or GHK) peptide that is famous for being a type I collagen fragment. The theory behind collagen-fragment peptides is that when collagen naturally breaks down in the skin, the resulting peptide fragments signal to the skin that it should get to work and create some nice, new collagen.

Adding in collagen fragment peptides, like GHK, might trick the skin into thinking that collagen has broken down and it's time to create some more. So Tripeptide-1 is believed to be able to stimulate collagen production in the skin, and more collagen means fewer wrinkles and younger looking skin. FYI; Tripeptide-1 is the same peptide that can be found in the famous Matrixyl 3000, but in Matrixyl a palmitic acid is attached to it to increase its oil solubility and thus skin penetration.

What-it-does: skin brightening

Hexapeptide-9 - goodie

An anti-aging peptide that can visibly reduce the length and depth of wrinkles, at least according to its manufacturer. In vitro (meaning it was done in the lab, not on real people) studies show that it enhances epidermal regeneration, collagen type I and III synthesis as well as the synthesis of other important skin proteins.

Also-called: Form of Retinoids | What-it-does: cell-communicating ingredient | Irritancy: 1-3 | Comedogenicity: 1-3

It's an ester form of vitamin A (retinol + palmitic acid) that belongs to the "retinoid family". The retinoid family is pretty much the royal family of skincare, with the king being the FDA-approved anti-aging ingredient tretinoin. Retinol is also a very famous member of the family, but it's like Prince George, two steps away from the throne. Retinyl palmitate will be then Prince Charlotte (George's little sister), quite far (3 steps) away from the throne. 

By steps, we mean metabolic steps. Tretinoin, aka retinoic acid, is the active ingredient our skin cells can understand and retinyl palmitate (RP) has to be converted by our metabolic machinery to actually do something. The conversion is a 3 step one and looks like this:

Also-called: Vitamin H

Also called vitamin H, biotin is the main component of many enzymes in our body. A nice ingredient to take as a supplement for stronger nails and hair. When you do not take it as a supplement its effects are a bit more questionable but according to manufacturer info it can smooth the skin and strengthen the hair.

Ascorbic Acid - superstar
Also-called: Vitamin C, L-ascorbic acid | What-it-does: antioxidant, skin brightening, buffering
  • Works best between a concentration of 5-20%
  • Boosts the skin’s own collagen production
  • Fades pigmentation and brown spots
  • If used under sunscreen it boosts its UV protection
  • Extremely unstable and oxidizes very easily in presence of light or air
  • Stable in solutions with water only if pH is less than 3.5 or in waterless formulations
  • Vit E + C work in synergy and provide superb photoprotection
  • Ferulic acid doubles the photoprotection effect of Vit C+E and helps to stabilize Vit C
  • Potent Vit. C serums might cause a slight tingling on sensitive skin

What-it-does: surfactant/cleansing, emulsifying, perfuming | Irritancy: 0 | Comedogenicity: 3

A 14 carbon length fatty acid that can be naturally found in nutmeg, palm kernel oil, coconut oil and butter fat. It's used as a foam building cleansing agent. Paula Begoun writes that it can be a bit drying to the skin. 

Also-called: Matrixyl, Pal-KTTKS, Formerly Palmitoyl Pentapeptide-3 | What-it-does: cell-communicating ingredient

A pretty famous and better-researched peptide consisting of five amino acids (the building blocks of all proteins). It was created in a joint effort by the French ingredient supplier, Sederma and the cosmetics industry big shot, Procter&Gamble.

The amino acid sequence of the peptide is lysine–threonine–threonine–lysine–serine (KTTKS). Sometimes, it's also called collagen pentapeptide, as it's a subfragment of skin-structure-giving type I collagen. The KTTKS amino sequence is then attached for better oil solubility and skin penetration to palmitic acid and BOOM; we get Palmitoyl Pentapeptide-4. 

Also-called: Biopeptide El, pal-VGVAPG, Palmitoyl Oligopeptide (old name) | What-it-does: cell-communicating ingredient

A six amino acid peptide that is claimed to improve firmness and skin tone. Its amino acid sequence is Val-Gly-Val-Ala-Pro-Gly that is also called the "spring fragment" and is repeated six times in the important skin protein, elastin molecule.

The manufacturer made a double-blind, one-month long clinical study on 10 women and found that twice a day application of 4%  Biopeptide El improved skin firmness by 33% and skin tone by 20%. 

We don't have description for this ingredient yet.

Also-called: Epidermal Growth Factor, EGF, rh-Oligopeptide-1 | What-it-does: cell-communicating ingredient

Sh-Oligopeptide-1 is the famous molecule, which is also called Epidermal Growth Factor or EGF. Chemically speaking, Growth Factors are largish peptides or smallish proteins, or to put it in another way, medium-length amino acid sequences (EGF consists of 53 amino acids).  Biologically speaking, Growth Factors are cellular signal molecules that can stimulate cell growth, proliferation, healing and/or differentiation. 

There are lots of Growth Factors and EGF is just one of them. The topic of "Growth Factors and skincare" is a big, confusing and controversial one and we will try our best to summarize the story for you, including the pros and the cons. 

Also-called: Basic Fibroblast Growth Factor, FGF2, rh-Polypeptide-1 | What-it-does: cell-communicating ingredient

Sh-Polypeptide-1 is a cell signaling protein also called Basic Fibroblast Growth Factor and is twin sister to Acidic Fibroblast Growth Factor. We can write here pretty much the same things as we did on aFGF: it is a mitogenic (= stimulates cell proliferation) ingredient that stimulates fibroblast cell growth and proliferation. According to manufacturer info, it also stimulates the synthesis of collagen and other extracellular-matrix (the gooey stuff between cells) components. 

Growth Factors and skincare is a big, complicated and controversial topic, so if you wanna know more, we have a more detailed explanation on Epidermal Growth Factor, the most common one used in skincare.

Also-called: Insulin-like growth factor 1, IGF-1, rh-Oligopeptide-2 | What-it-does: cell-communicating ingredient

Sh-Oligopeptide-2 is also called Insulin-like growth factor 1 and it belongs to the same group of ingredients (Growth Factors) as its better-known sister, Epidermal Growth Factor or Sh-Oligopeptide-1. This guy consists of 70 amino acids and, similar to EGF, it is also claimed to stimulate cell proliferation and wound healing. There is also a study that indicates EGF and IGF1 work in synergy to promote keratinocyte (skin cell) proliferation. 

The topic of Growth Factors in skincare is complex and controversial. If you are new to it, read our shiny explanation on EGF to get a (hopefully) balanced impression about the pros and cons.

Also-called: Rh-Polypeptide-3

Also-called: Vascular Endothelial Growth Factor, VEGF, rh-Polypeptide-9, part of BIO-Placenta | What-it-does: cell-communicating ingredient

Sh-Polypeptide-9 is a cell signaling protein also called Vascular Endothelial Growth Factor. As its name suggests, its main function is to stimulate the formation of blood vessels. As to what it does in cosmetic products, we found manufacturers info claiming that it plays a role in supplying fibroblast cells (VIP skin cells that make collagen) with nutrients, in the growth and migration of cells and in wound healing

It usually comes to the formula as part of a Growth Factor mix trade named BIO-Placenta, that combines EGF, IGF-1, FGF1, FGF2 and this guy to form a synergistic growth factor cocktail. BIO Placenta is claimed to do pretty much everything you would want from an anti-aging active including anti-wrinkle, skin rejuvenation, elasticity enhancement, moisturizing and cell vitalization properties. 

Also-called: Acidic Fibroblast growth factor, FGF1, rh-Polypeptide-11 | What-it-does: cell-communicating ingredient

Sh-Polypeptide-11 is a medium sized cell signaling molecule also called Acidic Fibroblast Growth Factor. It belongs to the same group of ingredients (Growth Factors) as its better-known sister, Epidermal Growth Factor or Sh-Oligopeptide-1. As its name suggests, FGF can stimulate the growth and proliferation of fibroblast cells (VIP cells that produce among other things collagen). According to manufacturer info, it also stimulates skin regeneration, wound healing and collagen and elastin synthesis. 

As for research, we could find an in-vitro study that proved that "Recombinant FGF-1 strongly stimulated fibroblast and keratinocyte proliferation. However, the transition of this protein through the SC required an appropriate carrier system - lipid spheres."

What-it-does: emulsifying, surfactant/cleansing | Irritancy: 0 | Comedogenicity: 0

A common little helper ingredient that helps water and oil to mix together, aka emulsifier. 

The number at the end refers to the oil-loving part and the bigger the number  the more emulsifying power it has. 20 is a weak emulsifier, rather called solubilizer used commonly in toners while 60 and 80 are more common in serums and creams.

What-it-does: antioxidant

A handy multifunctional ingredient that works as a preservative booster, as well as an antioxidant and soothing agent

What-it-does: preservative, deodorant

If you have spotted ethylhexylglycerin on the ingredient list, most probably you will see there also the current IT-preservative, phenoxyethanol. They are good friends because ethylhexylglycerin can boost the effectiveness of phenoxyethanol (and other preservatives) and as an added bonus it feels nice on the skin too.

Also, it's an effective deodorant and a medium spreading emollient

It’s a handy multi-tasking ingredient that gives the skin a nice, soft feel. At the same time, it also boosts the effectiveness of other preservatives, such as the nowadays super commonly used phenoxyethanol

The blend of these two (caprylyl glycol + phenoxyethanol) is called Optiphen, which not only helps to keep your cosmetics free from nasty things for a long time but also gives a good feel to the finished product. It's a popular duo.

A multi-functional, silky feeling helper ingredient that can do quite many things. It's used as an emulsion stabilizer, solvent and a broad spectrum antimicrobial. According to manufacturer info, it's also a moisturizer and helps to make the product feel great on the skin. It works synergistically with preservatives and helps to improve water-resistance of sunscreens. 

What-it-does: preservative

A helper ingredient that helps to make the products stay nice longer, aka preservative. It works mainly against fungi. 

It’s pH dependent and works best at acidic pH levels (3-5). It’s not strong enough to be used in itself so it’s always combined with something else, often with potassium sorbate.

Fragrance - icky
Also-called: Fragrance, Parfum;Parfum/Fragrance | What-it-does: perfuming

Exactly what it sounds: nice smelling stuff put into cosmetic products so that the end product also smells nice. Fragrance in the US and parfum in the EU is a generic term on the ingredient list that is made up of 30 to 50 chemicals on average (but it can have as much as 200 components!). 

If you are someone who likes to know what you put on your face then fragrance is not your best friend - there's no way to know what’s really in it.
