Ingredients explained

What-it-does: abrasive/scrub

We don't have description for this ingredient yet.

Also-called: Water | 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. 

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: moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0

It's a sweet tasting sugar substitute that helps your skin to hold onto water when used in cosmetic products. It also helps to thicken up products and give them a bit more slip. 

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 at higher concentrations up to 20-40% (around 10% is a good usability-effectiveness sweet spot)
  • High-glycerin moisturizers are awesome for treating severely dry skin

What-it-does: perfuming, soothing

Also-called: SLS | What-it-does: surfactant/cleansing, emulsifying | Comedogenicity: 0

The famous or rather infamous SLS (not to be confused with SLES). It is a cleansing agent known for being too good at the job and potentially irritating the skin. But, on the positive side,  it can produce copious, creamy and luxurious foam compared to the more gentle and thus nowadays much more commonly used Sodium Laureth Sulfate.

In fact, SLS is so good at irritating the skin that it is very commonly used in dermatological studies just for that. It is a so-called "primary irritant", a substance that irritates the skin in one go (without prior sensitization) but doesn't do any other big harm (such as being carcinogenic or systematically toxic - those claims are not true). Also, the formula can greatly influence the irritating potential of SLS, and mixing it with other cleaning agents makes it milder

If it's not in a cleanser, it works as an emulsifier or even as a penetration enhancer for active materials. 

Also-called: Titanium Dioxide/Ci 77891 | What-it-does: colorant | Irritancy: 0 | Comedogenicity: 0

Ci 77891 is the color code of titanium dioxide. It's a white pigment with great color consistency and dispersibility.

What-it-does: viscosity controlling

A natural polysaccharide (big sugar molecule) coming from red edible seaweeds. It is used as a helper ingredient for its gelling, thickening and stabilizing properties.  

Also-called: Carboxymethyl Cellulose | What-it-does: viscosity controlling, emulsion stabilising | Irritancy: 0 | Comedogenicity: 0

A cellulose (the big molecule found in the cell wall of green plants) derivative that is used as an emulsion stabilizer and thickener

What-it-does: buffering

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.

Menthol - icky
What-it-does: soothing

Menthol needs no introduction: it's the thing that causes the cooling sensation so well-known both from cosmetic products as well as a bunch of other things like chocolate, chewing gum, toothpaste or cigarette. It's a natural compound that comes from the essential oil of Mentha species (peppermint oil contains 40-50% menthol) and it gives them their typical minty smell and flavor.

As for skincare, menthol seems to be a mixed bag. Apart from the cool cooling sensation (that might last up to 70 mins!), it also has painkilling, itch reducing, antibacterial, antifungal and even penetration enhancing properties. On the other hand, it also seems to act as a skin irritant that increases trans-epidermal water loss (the water that evaporates from the outer layer of the skin) and thus contributes to drying out the skin.

What-it-does: colorant
