Ingredients explained

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. 

Expand to read more

Once inside the skin, it hydrates, but not from the outside - putting pure water on the skin (hello long baths!) is drying. 

One more thing: the water used in cosmetics is purified and deionized (it means that almost all of the mineral ions inside it is removed). Like this, the products can stay more stable over time. 

What-it-does: emollient, solvent

A super commonly used 5 unit long, cyclic structured silicone that is water-thin and does not stay on the skin but evaporates from it (called volatile silicone). Similar to other silicones, it gives skin and hair a silky, smooth feel

It's often combined with the non-volatile (aka stays on the skin) dimethicone as the two together form a water-resistant, breathable protective barrier on the skin without a negative tacky feel.

Zinc Oxide - goodie
What-it-does: sunscreen

When it comes to sunscreen agents, Zinc Oxide is pretty much in a league of its own. It's a physical (or inorganic) sunscreen that has a lot in common with fellow inorganic sunscreen Titanium Dioxide (TiO2) but a couple of things make it superior even to TiO2.

If physical sunscreens don't tell you anything, go ahead and read about the basics here. Most of what we wrote about Titanium Dioxide is also true for Zinc Oxide so we will focus here on the differences. 

Expand to read more

The first main difference is that while TiO2 gives a nice broad spectrum protection, Zinc Oxide has an even nicer and even broader spectrum protection. It protects against UVB, UVA II, and UVA I almost uniformly, and is considered to be the broadest range sunscreen available today

It's also highly stable and non-irritating. So much so that Zinc Oxide also counts as a skin protectant and anti-irritant. It's also often used to treat skin irritations such as diaper rash.

As for the disadvantages, Zinc Oxide is also not cosmetically elegant. It leaves a disturbing whitish tint on the skin, although, according to a 2000 research paper by Dr. Pinnell, it's slightly less white than TiO2. Still, it's white and disturbing enough to use Zinc Oxide nanoparticles more and more often. 

We wrote more about nanoparticles and the concerns around them here, but the gist is that if nanoparticles were absorbed into the skin that would be a reason for legitimate health concerns. But luckily, so far research shows that sunscreen nanoparticles are not absorbed but remain on the surface of the skin or in the uppermost (dead) layer of the skin. This seems to be true even if the skin is damaged, for example, sunburnt. 

All in all, if you've found a Zinc Oxide sunscreen that you are happy to use every single day, that's fantastic and we suggest you stick with it. It's definitely one of the best, or probably even the best option out there for sun protection available worldwide. 

Titanium Dioxide - goodie
What-it-does: sunscreen

Titanium Dioxide is one of the two members of the elite sunscreen group called physical sunscreens (or inorganic sunscreens if you’re a science geek and want to be precise).

Traditionally, UV-filters are categorized as either chemical or physical. The big difference is supposed to be that chemical agents absorb UV-light while physical agents reflect it like a bunch of mini umbrellas on top of the skin. While this categorization is easy and logical it turns out it's not true. A recent, 2016 study shows that inorganic sunscreens work mostly by absorption, just like chemical filters, and only a little bit by reflection (they do reflect the light in the visible spectrum, but mostly absorb in the UV spectrum).

Expand to read more

Anyway, it doesn't matter if it reflects or absorbs, Titanium Dioxide is a pretty awesome sunscreen agent for two main reasons: it gives a nice broad spectrum coverage and it's highly stable. Its protection is very good between 290 - 350 nm (UVB and UVA II range), and less good at 350-400 nm (UVA I) range. Regular sized Titanium Dioxide also has a great safety profile, it's non-irritating and is pretty much free from any health concerns (like estrogenic effect worries with some chemical filters).

The disadvantage of Titanium Dioxide is that it's not cosmetically elegant, meaning it's a white, "unspreadable" mess. Sunscreens containing Titanium Dioxide are often hard to spread on the skin and they leave a disturbing whitish tint. The cosmetic industry is, of course, really trying to solve this problem and the best solution so far is using nanoparticles. The itsy-bitsy Nano-sized particles improve both spreadability and reduce the whitish tint a lot, but unfortunately, it also introduces new health concerns. 

The main concern with nanoparticles is that they are so tiny that they are absorbed into the skin more than we want them (ideally sunscreen should remain on the surface of the skin). Once absorbed they might form unwanted complexes with proteins and they might promote the formation of evil free radicals. But do not panic, these are concerns under investigation. A 2009 review article about the safety of nanoparticles summarizes this, "to date, in-vivo and in-vitro studies have not demonstrated percutaneous penetration of nanosized particles in titanium dioxide and zinc oxide sunscreens". The English translation is, so far it looks like sunscreens with nanoparticles do stay on the surface of the skin where they should be.  

All in all, Titanium Dioxide is a famous sunscreen agent and for good reason, it gives broad spectrum UV protection (best at UVB and UVA II), it's highly stable, and it has a good safety profile. It's definitely one of the best UV-filter agents we have today, especially in the US where new-generation Tinosorb filters are not (yet) approved. 

What-it-does: emulsifying

A silicone emulsifier that helps water and silicone oils to mix nicely together. It can also be used together with plant oil + silicone oil mixtures. 

Glycerin - goodie
Also-called: Glycerol | What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0
  • A natural moisturizer that’s also in our skin
  • Super common, used for more than 50 years
  • Not only a simple moisturizer but plays an important role in keeping the stuff between our skin cells healthy
  • High-glycerin moisturizers are awesome for treating severely dry skin
Read all the geeky details about Glycerin here >>

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

Sunflower does not need a big intro as you probably use it in the kitchen as cooking oil, or you munch on the seeds as a healthy snack or you adore its big, beautiful yellow flower during the summer - or you do all of these and probably even more. And by even more  we mean putting it all over your face as sunflower oil is one of the most commonly used plant oils in skincare.

It’s a real oldie: expressed directly from the seeds, the oil is used not for hundreds but thousands of years. According to The National Sunflower Association, there is evidence that both the plant and its oil were used by American Indians in the area of Arizona and New Mexico about 3000 BC. Do the math: it's more than 5000 years – definitely an oldie.

Expand to read more

Our intro did get pretty big after all (sorry for that), so let's get to the point finally: sunflower oil - similar to other plant oils - is a great emollient that makes the skin smooth and nice and helps to keep it hydrated. It also protects the surface of the skin and enhances the damaged or irritated skin barrier. Leslie Bauman notes in Cosmetic Dermatology that one application of sunflower oil significantly speeds up the recovery of the skin barrier within an hour and sustains the results 5 hours after using it.

It's also loaded with fatty acids (mostly linoleic (50-74%)  and oleic (14-35%)). The unrefined version (be sure to use that on your skin!) is especially high in linoleic acid that is great even for acne-prone skin. Its comedogen index is 0, meaning that it's pretty much an all skin-type oil

Truth be told, there are many great plant oils and sunflower oil is definitely one of them.

What-it-does: emulsifying

A silicone emulsifier that helps water to mix nicely with silicone oils (aka water-in-silicone emulsifier). 

What-it-does: emollient

A fast spreading emollient ester (hexyl alcohol + lauric acid) that's used in water in oil emulsions or in water-free formulas. It gives a light skin feel. 

What-it-does: emulsifying

We don't have description for this ingredient yet.

What-it-does: emollient

A very 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, and it’s also easy to formulate with. No wonder it’s popular. 

What-it-does: emulsifying

A PEG-modified self-emulsifying crosslinked silicone elastomer surfactant that helps water to mix nicely with silicone oils, aka a water in silicone emulsifier. It creates highly stable micelle structures that break upon application of the product so it is ideal for  “water drop” like cream formulations.

Astaxanthin - goodie
What-it-does: antioxidant

An oil-loving, red-orange colored pigment that is becoming more and more well-known as a potent antioxidant.

If being an orange-colored pigment reminds you of beta-carotene from carrots, that is no coincidence: astaxanthin also belongs to the chemical group called carotenoids known for giving yellow, orange, or red color to plants. Our guy comes mostly from microalgae, a well-known and often used source is Haematococcus Pluvialis

Expand to read more

So Astaxanthin's main thing is being an antioxidant. You can take it as a supplement or slather it on your skin, it works both ways. A mouse skin study from 2012 found that a liposomal Astaxanthin formula prevented UV‐induced skin damage in multiple ways: UV-induced skin thickening, collagen reduction, and melanin formation were all hindered or prevented when the skin was pretreated with the Astaxanthin formula. 

Another study from 2012 examined the cosmetic benefits of Astaxanthin and found that combining oral supplementation (6mg/day) and topical application for 8 weeks in 30 volunteers showed improvements in skin wrinkle (crow’s feet), age spot size (cheek), elasticity (crow’s feet), skin texture (cheek) and moisture content of the skin (cheek).  If that would not be enough, a 2017 mouse study found our carotenoid molecule to be effective in speeding up wound healing.

Overall, Astaxanthin is an up and coming antioxidant nice to spot on any ingredient list. 

Also-called: Part of Celligent

Disodium Uridine Phosphate is a nucleotide (the building blocks of DNA and RNA) precursor that's claimed to support DNA repair in the cell, in particular, the process of nucleotide excision repair.

If you are wondering what the heck this means, let's back up: DNA is the super important big molecule in all our cells that serves as the recipe or template from which everything inside us is built. It is super important to have a flawless DNA as a messed up template will result in messed up biochemical molecules and all kinds of diseases. 

Expand to read more

Changes to DNA can happen just spontaneously (luckily super rare) or due to some external thing, such as UV light. Because a flawless DNA is so important, the body has repair mechanisms that can fix most of these changes. Due to UV light,  sometimes faulty lesions (called pyrimidine dimer) appear on the DNA strand and that can be fixed by nucleotide excision repair, where DNA repair enzymes cut out the faulty part, create the new, correct fragment and put it back in. 

So our guy, Disodium Uridine Phosphate might be able to help with this super useful repair process, though the manufacturer data we have seen examined only the whole "Celligent" complex that also has other antioxidants in it. The whole complex was found in-vivo (with 20 volunteers) to reduces erythema (redness) and promote the regeneration of skin damaged by UV irradiation but it's hard to know what specifically Disodium Uridine Phosphate contributed. 

 

What-it-does: antioxidant

We don't have description for this ingredient yet.

Also-called: Rosemary Leaf Extract | What-it-does: antioxidant, soothing, antimicrobial/antibacterial

The extract coming from the lovely herb, rosemary. It contains lots of chemicals, including flavonoids, phenolic acids, and diterpenes. Its main active is rosmarinic acid, a potent antioxidant, and anti-inflammatory. It has also anti-bacterial, astringent and toning properties. 

The leaves contain a small amount of essential oil (1-2%) with fragrant components, so if you are allergic to fragrance, it might be better to avoid it. 

Also-called: Tasmanian Pepper Extract | What-it-does: antioxidant, soothing

Tasmanian Pepper is a nice shrub living under hard conditions in the mountains of the Southeastern lands of Australia. It has small, round, purple-black berries that when dried, look like black pepper. Hence the name. 

As for skincare, the berries contain a couple of great actives. The primary one is called polygodial that has potent anti-inflammatory, anti-allergic and antimicrobial activity. According to the manufacturers in-vivo (made on real people) tests, Tasmanian Pepper Extract can relieve itching and burning sensation to a great extent (79% and 58% decrease) almost instantly (after only 5 mins).

Expand to read more

It also contains anthocyanins, that are well-known antioxidants. The berries are claimed to have an antioxidant power 3x greater than blueberries. A third active in the berries is called rutin, an anti-inflammatory agent that can strengthen capillaries. Thanks to this, Tasmanian Pepper might be able to help reduce dark undereye circles

All in all, an interesting plant extract with soothing and antioxidant activity.

What-it-does: antioxidant

Haematococcus Pluvialis is a microalgae known for being a rich source of powerful, up-and-coming antioxidant, Astaxanthin. The extract comes as a red-colored oily liquid prepared from the resting and astaxanthin accumulating cells of the otherwise green algae. 

As an antioxidant, it promises to protect against photodamage and thus help to delay skin photoaging. We have written more about Astaxanthin and its benefits here>> 

What-it-does: antioxidant

We don't have description for this ingredient yet.

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

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).

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

Expand to read more

BTW, it's also a building block of a bunch of important and famous peptides, including copper-tripeptide-1, palmitoyl tripeptide-1 or palmitoyl hexapeptide-12.

Alanine - goodie

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

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.

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.

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.  

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

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

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

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).

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

PCA stands for Pyrrolidone Carboxylic Acid and though it might not sound like it, it is a thing that can be found naturally in our skin. The sodium salt form of PCA is an important skin-identical ingredient and great natural moisturizer that helps the skin to hold onto water and stay nicely hydrated. 

Pca - goodie
Also-called: Pyrrolidone Carboxylic Acid | What-it-does: skin-identical ingredient, moisturizer/humectant

PCA stands for Pyrrolidone Carboxylic Acid and though it might not sound like it, it is a thing that can be found naturally in our skin. In fact, after amino acids, it is the second biggest NMF component of the skin with 12% being PCA of the NMF composition of normal skin.  So similar to other NMFs, it's a skin goodie that helps the skin to hold onto water and stay nicely hydrated. 

Sodium Lactate - goodie

The sodium salt of lactic acid. It's a great skin moisturizer and also used to regulate the pH value of the cosmetic formula. It's a natural ingredient approved by both ECOCERT and COSMOS.

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

What-it-does: moisturizer/humectant

We don't have description for this ingredient yet.

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

Fancy name for fruit sugar. It has nice water-binding properties and helps to keep skin hydrated

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

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

Urea - goodie
Also-called: Carbamide | What-it-does: skin-identical ingredient, moisturizer/humectant

Yes, it's the thing that can be found naturally in pee. And in the skin. It is an awesome natural moisturizing factor, aka NMF.  NMFs are important components that help the skin to hold onto water and keep it plump, elastic and hydrated. Urea makes up about 7% of NMFs next to other things such as amino acids (40%), PCA (12%) or Lactate (12%).

What makes urea special, is that it is not only a simple moisturizer, but it is thought to be a "small-molecule regulator of epidermal structure and function" meaning that it has a bunch of extra biological activities. It acts as a mild keratolytic agent (some of its moisturizing action is thought to come from urea's ability to break down bonds in the protein called filaggrin and thus freeing up amino acids in the skin), enhances antimicrobial peptide expression and improves skin barrier function

Expand to read more

Being a mild keratolytic agent and strong moisturizer means that high-percentage (10-40%) urea treatments are found effective in a bunch of skin disorders connected to excessive dryness and malfunctioning skin barrier such as ichthyosis, xerosis, psoriasis, eczema and seborrheic dermatitis.  

Overall, just like glycerin, urea is a real oldie but a goodie, a nice ingredient in any moisturizer.

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: 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". 

Expand to read more

In spite of this, if you search for "hyaluronic acid vs sodium hyaluronate" you will find on multiple places that sodium hyaluronate is smaller and can penetrate the skin better. Chemically, this is definitely not true, as the two forms are almost the same, both are polymers and the subunits can be repeated in both forms as much as you like. (We also checked Prospector for sodium hyaluronate versions actually used in cosmetic products and found that the most common molecular weight was 1.5-1.8 million Da that absolutely counts as high molecular weight).

What seems to be a true difference, though, is that the salt form is more stable, easier to formulate and cheaper so it pops up more often on the ingredient lists. 

If you wanna become a real HA-and-the-skin expert you can read way more about the topic at hyaluronic acid (including penetration-questions, differences between high and low molecular weight versions and a bunch of references to scientific literature).

Linoleic Acid - goodie
Also-called: LA, omega-6 fatty acid, 18:2 cis-9,12, Form of Vitamin F | What-it-does: skin-identical ingredient, emollient

The famous omega-6 fatty acid, the mother of all ω-6 fatty acids in our body. It is a so-called polyunsaturated fatty acid meaning it has more than one (in this case two) double bonds and a somewhat kinky structure that makes LA and LA-rich oils a thin liquid.

It is also an essential fatty acid meaning our body cannot synthesize it and has to take it from food. This is not hard at all as plenty of nuts (such as flax, poppy or sesame seeds) and vegetable oils (such as sunflower or safflower) are rich in LA. The hard thing seems to be eating enough omega-3-s, more specifically eating a healthy ratio of omega-6 to omega-3, but that is a topic for a what-is-good-to-eat-site and not for us. 

Expand to read more

As for linoleic acid and the skin, LA is a really important little guy found naturally in our skin. It is the most abundant fatty acid in the epidermis and it serves as a structural precursor for important skin lipids called ceramides. Knowing this, it will not come as a surprise that Linoleic acid has a central role in the structure and function of stratum corneum permeability, aka healthy skin barrier.  LA deficiency leads to an impaired more permeable skin barrier and the topical application of LA-rich sunflower oil can fix this issue rapidly (while oleic-rich olive oil did not have the same barrier repairing effect).

LA is not only important for dry, barrier damaged skin types but also for acne-prone skin. Research shows that problem skin has lower levels of linoleic acid (and higher levels of oleic acid) than normal skin. So LA-deficiency in the skin seems to be connected not only to an impaired skin barrier but also to acne and smearing LA all over your face might help with your problem skin. A double-blind study using a 2.5% LA gel for 4 weeks found a 25% reduction in the size of microcomedones, the tiny blocked pores that can later lead to acne.

If that was not enough, we have one more thing to report about LA.  It lightens hyperpigmentation (aka UVB caused sun spots) both by blocking the melanin production of melanocytes (the skin cells that make the pigment melanin) and by enhancing the desquamation of melanin pigment from the upper layers of the skin.

Overall, linoleic acid is a multi-functional skin goodie with barrier repairing, acne-reducing, and skin-lightening magic abilities. It's a nice one to spot on the ingredient list pretty much for any skin type. 

Also-called: Omega-9 fatty acid | What-it-does: emollient, emulsifying

A common fatty acid that can be found in lots of plant oils. Its name, "oleic", means derived from olive oil, a plant oil rich in oleic acid, but avocado, macadamia and marula oils, just to name a few, are also oleic rich.

Its chemical structure is monounsaturated, meaning it has one double bond (cis-9) that makes it less kinky than polyunsaturated fatty acids with multiple double bonds. Less kinkiness means that oleic acid and OA-rich oils are a bit thicker and heavier than their LA-rich siblings.

Expand to read more

Maybe this thickness is the reason that Oleic acid is considered comedogenic, and if you have acne-prone skin avoid OA-rich plant oils, and choose linoleic acid-rich versions instead.

The thickness of OA also means that OA-rich oils are considered more nourishing and moisturizing than their LA-rich counterparts, and are generally considered to be more suitable for dry, mature skin types. 

As for oleic acid in its free form (and by free we mean that it is not bound up in a triglyceride structure like it is in oils), it mostly serves as an emulsifier or emulsion stabilizer in small amounts in regular cosmetic products. It is also quite well researched and is used in the pharmaceutical industry as a penetration enhancer

We don't have description for this ingredient yet.

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: emulsifying, emollient, viscosity controlling | Irritancy: 0 | Comedogenicity: 2

A common multi-tasker fatty acid. It helps water and oil to mix (emulsifier), it makes your skin feel smooth (emollient) and can help to thicken up products.

We don't have description for this ingredient yet.

What-it-does: emulsifying

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

What-it-does: viscosity controlling

We don't have description for this ingredient yet.

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. 

A clear, colorless liquid that works as a solvent and viscosity decreasing ingredient.

Tocopherol - superstar
Also-called: Vitamin E | What-it-does: antioxidant | Irritancy: 2 | Comedogenicity: 2
  • Primary fat-soluble antioxidant in our skin
  • Significant photoprotection against UVB rays
  • Vit C + Vit E work in synergy and provide great photoprotection
  • Has emollient properties
  • Easy to formulate, stable and relatively inexpensive

Also-called: Aluminum Oxide, Al2O3 | What-it-does: viscosity controlling, absorbent/mattifier

A multi-functional helper ingredient that's used mainly as a pigment carrier.  The pigment can be an inorganic sunscreen (such as titanium dioxide) or a colorant that is blended with alumina platelets and then often coated with some kind of silicone (such as triethoxycaprylylsilane). This special treatment enables pigments to be evenly dispersed in the formula and to be spread out easily and evenly upon application. It is super useful both for mineral sunscreens as well as for makeup products. 

Other than that, alumina can also be used as an absorbent (sometimes combined with the mattifying powder called polymethylsilsesquioxane), a viscosity controlling or an opacifying (reduces the transparency of the formula) agent.

Citric Acid - goodie
What-it-does: exfoliant, buffering

Citric acid comes from citrus fruits and is an AHA. If these magic three letters don’t tell you anything, click here and read our detailed description on glycolic acid, the most famous AHA. 

So citric acid is an exfoliant, that can - just like other AHAs - gently lift off the dead skin cells of your skin and make it more smooth and fresh.

There is also some research showing that citric acid with regular use (think three months and 20% concentration) can help sun-damaged skin, increase skin thickness and some nice hydrating things called glycosaminoglycans in the skin. 

But according to a comparative study done in 1995, citric acid has less skin improving magic properties than glycolic or lactic acid. Probably that’s why citric acid is usually not used as an exfoliant but more as a helper ingredient in small amounts to adjust the pH of a formulation. 

Also-called: EDDS | What-it-does: chelating

A helper ingredient that helps to neutralize the metal ions in the formula (they usually come from water) so it stays nice longer. The special property of this particular ingredient is that it's more effective against more problematic ions, like Cu (copper) and Fe (iron) compared to less problematic ones like Ca (calcium)  and Mg (magnesium).

Also-called: Salt | What-it-does: viscosity controlling

Sodium chloride is the fancy name of salt. Normal, everyday table salt

It’s a common little helper ingredient in cosmetics that helps to increase the volume of a product (bulking), to disguise any unpleasant smell (masking) or to thicken up a formula (viscosity controlling). Sometimes it’s also used as a scrub.

Also-called: lye | What-it-does: buffering

The unfancy name for it is lye. It’s a solid white stuff that’s very alkaline and used in small amounts to adjust the pH of the product and make it just right. 

For example, in case of AHA or BHA exfoliants, the right pH is super-duper important, and pH adjusters like sodium hydroxide are needed.

BTW, lye is not something new. It was already used by ancient Egyptians to help oil and fat magically turn into something else. Can you guess what? Yes, it’s soap. It still often shows up in the ingredient list of soaps and other cleansers.

Sodium hydroxide in itself is a potent skin irritant, but once it's reacted (as it is usually in skin care products, like exfoliants) it is totally harmless.

What-it-does: preservative

It’s pretty much the current IT-preservative. It’s safe and gentle, but even more importantly, it’s not a feared-by-everyone-mostly-without-scientific-reason paraben.

It’s not something new: it was introduced around 1950 and today it can be used up to 1% worldwide. It can be found in nature - in green tea - but the version used in cosmetics is synthetic.

Other than having a good safety profile and being quite gentle to the skin it has some other advantages too. It can be used in many types of formulations as it has great thermal stability (can be heated up to 85°C) and works on a wide range of pH levels (ph 3-10). 

It’s often used together with ethylhexylglycerin as it nicely improves the preservative activity of phenoxyethanol.

A little helper ingredient that works as a preservative. It works against bacteria and some species of fungi and yeast. It's often combined with IT-preservative, phenoxyethanol.
