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. 

What-it-does: emollient | Irritancy: 0 | Comedogenicity: 1

Probably the most common silicone of all. It is a polymer (created from repeating subunits) molecule and has different molecular weight and thus different viscosity versions from water-light to thick liquid.

As for skincare, it makes the skin silky smooth, creates a subtle gloss and forms a protective barrier (aka occlusive). Also, works well to fill in fine lines and wrinkles and give skin a plump look (of course that is only temporary, but still, it's nice). There are also scar treatment gels out there using dimethicone as their base ingredient. It helps to soften scars and increase their elasticity. 

What-it-does: emollient, solvent

A water-loving emollient and humectant that gives a nice skin feel and slip to the product. It works well with facial toners.

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

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. 

Also-called: Watermelon Fruit Extract;Citrullus Lanatus Fruit Extract | What-it-does: antioxidant

We love a cold slice of watermelon on a hot summer day and we love watermelon as a skincare ingredient. It's really full of good-for-the-skin stuff: it contains a bunch of vitamins (A, B, C and E), mineral salts (K, Mg, Ca and Fe), amino acids citrulline and arginine and antioxidant carotenoids and phenolics

It's especially rich in potent antioxidant, lycopene (a type of carotenoid), the cool pigment that's responsible for the red color of the watermelon. According to manufacturer info, in-vitro (made in the lab not on real people) studies show that watermelon extract gives significant DNA protection against UV damage. The in-vivo (made on real people) study also confirmed this and the watermelon formula showed 25% increase in skin protection compared to placebo.

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. 

Alcohol - icky
Also-called: Ethanol | What-it-does: antimicrobial/antibacterial, solvent, viscosity controlling, astringent

Simply alcohol refers to ethanol and it's a pretty controversial ingredient. It has many instant benefits: it's a great solvent, penetration enhancer, creates cosmetically elegant, light formulas, great astringent and antimicrobial. No wonder it's popular in toners and oily skin formulas. 

The downside is that it can be very drying if it's in the first few ingredients on an ingredient list. 

What-it-does: moisturizer/humectant

We don't have description for this ingredient yet.

Also-called: Apple Fruit Extract | What-it-does: moisturizer/humectant

Apple needs no introduction as one of the most common fruits on planet Earth. It's not only a healthy fruit snack, it's also a goodie if you put in all over your face. 

It's loaded with proteins, starch, sugars, acids, vitamins and salts. The sugars (mainly fructose, glucose, sucrose) give apple fruit extract nice moisturizing and smoothing properties, while the acids (mainly malic  and gallic acid) give it mild exfoliant, skin brightening and antibacterial properties. 

Also-called: Pineapple Fruit Extract | What-it-does: soothing, moisturizer/humectant

A goodie fruit extract coming from the lovely pineapple. It contains a bunch of good-for-the-skin stuff:  bromelain and fruit acids  have mild exfoliant properties, and fruit sugars and amino acids give the pineapple fruit nice moisturizing and soothing properties. 

There is also a pineapple extract called pineapple ceramide on the market that's claimed to be loaded with a glucose linked ceramide derivative called glucoceramide. According to the manufacturer, glucoceramide is not only a skin moisturizer but it also helps to lighten the skin and make it more smooth.

What-it-does: antioxidant

If you are looking for a reason why red wine is good for you, good news, you have found it! Resveratrol, aka the "red grape antioxidant" is the thing that's suspected to keep the French from coronary heart disease despite their not so healthy eating habits (such as high saturated fat intake).

So resveratrol, found in the seed and skin of the red grape (and berries), is a pretty well-known and well-studied molecule that has potent antioxidant, anti-inflammatory, and anticarcinogenic abilities. Most of the studies were done examining resveratrol's promising anti-cancer properties, but as for skin care, it shows a potent protective effect against UV-caused oxidative stress as well as promising effects against multiple types of skin cancer including the most severe one, melanoma (as an adjuvant therapy). 

We don't have description for this ingredient yet.

Also-called: Japanese Pepper, Korean Pepper, Sanshō, Chopi | What-it-does: antioxidant, antimicrobial/antibacterial, preservative

If you are into Japanese cuisine, you might know this guy as Japanese pepper or Sanshō pepper that is known for its unique fresh aroma and appetite increasing spicy sensation.

As for the skin benefits of Zanthoxylum Piperitum, it might have antioxidant effects (with active components called hyperoside and quercitrin), but more importantly, it is an antibacterial and natural preservative agent. It is pretty common in K-Beauty products, as it's one of the three natural extracts that make up the popular Korean preservative called EURO-NApre. 

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: 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". 

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). 

Beta-Glucan - goodie

Beta-Glucan is a nice big molecule composed of many smaller sugar molecules (called polysaccharide). It’s in the cell walls of yeast, some mushrooms, seaweeds, and cereals.

It’s a real goodie no matter if you eat it or put it on your face. Eating it is anti-diabetic, anti-cancer, and even lowers blood cholesterol. 

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: perfuming

We don't have description for this ingredient yet.

Also-called: Skullcap Root Extract | What-it-does: soothing, antioxidant, antimicrobial/antibacterial, astringent, moisturizer/humectant

A traditional Chinese herbal medicine loaded with potent antioxidant and anti-inflammatory flavonoids such as baicalin, baicalein, and wogonin.

If that would not be enough, Skullcap Root is also claimed to have antimicrobial and antifungal properties (also against P.acnes and Malassezia furfur) as well as some skin-brightening activity. A multi-functional skin-goodie.

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: colorant

We don't have description for this ingredient yet.

A white powdery thing that's the major component of glass and sand. In cosmetics, it’s often in products that are supposed to keep your skin matte as it has great oil-absorbing abilities. It’s also used as a helper ingredient to thicken up products or suspend insoluble particles. 

Glycolic Acid - superstar
What-it-does: exfoliant, buffering
  • It’s the most researched AHA with the most proven skin benefits
  • It gently lifts off dead skin cells to reveal newer, fresher, smoother skin
  • It can help skin’s own collagen production that results in firmer, younger skin
  • It can fade brown spots caused by sun damage or PIH
  • 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)
  • Slight stinging or burning with a stronger AHA product is normal
  • If your skin is very sensitive, rosacea prone choose rather a BHA or PHA product

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.
