Lierac Sebologie Deep-Cleansing Scrub Mask
Ingredients explained

Also-called: Aqua;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. 

Kaolin - goodie
Also-called: Type of clay, China clay | What-it-does: colorant, absorbent/mattifier, abrasive/scrub | Irritancy: 0 | Comedogenicity: 0

Kaolin is a type of clay or to be precise, a naturally occurring hydrous aluminum silicate. When you hear clay, you probably think of a muddy greenish-black mess, but that one is bentonite, and this one is a fine, white powder. It is so white that it's also often used, in small amounts, as a helper ingredient to give opacity and whiteness to the cosmetic formulas.

As a clay, it's absorbent and can suck up excess sebum and gunk from your skin, but less so than the more aggressive bentonite. As it's less absorbent, it's also less drying and gentler on the skin, so it's ideal for dry and sensitive skin types.  

Also-called: Rice Starch | What-it-does: viscosity controlling, absorbent/mattifier

What-it-does: anti-acne, soothing, deodorant

If you are fighting acne and have looked into oral supplements, chances are that zinc gluconate sounds familiar to you. It is a zinc salt that has research proving it to be effective against inflammatory acne, though not quite as effective as the antibiotic minocycline (31.2% vs. 63.4% success rate). However, zinc supplements are easily available, have little-to-no side effects, so supplementing them with a 30mg per day dose can still be a good idea.

As for smearing zinc gluconate all over your face, it is also not a bad idea. Zinc has multiple magic abilities: it is antibacterial (including evil, acne-causing P. acnes) and sebum-regulating (5α-reductase inhibitor), great for acne-prone skin types. It also stimulates antioxidant enzyme systems (mainly superoxide dismutase) and has nice wound healing abilities acting mainly in the first, proliferation phase. So great for skin types in need of healing and soothing.

What about the gluconate part? It is there to promote the absorption and bioavailability of zinc and also plays a role in cellular regeneration (involved in the synthesis of ribose sugars, structural components of DNA and RNA).

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: 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: 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. 

We don't have description for this ingredient yet.

What-it-does: emollient, emulsifying, viscosity controlling, surfactant/cleansing, 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.

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

A super common, waxy, white, solid stuff that helps water and oil to mix together, gives body to creams and leaves the skin feeling soft and smooth.

Chemically speaking, it is the attachment of a glycerin molecule to the fatty acid called stearic acid. It can be produced from most vegetable oils (in oils three fatty acid molecules are attached to glycerin instead of just one like here) in a pretty simple, "green" process that is similar to soap making. It's readily biodegradable.

It also occurs naturally in our body and is used as a food additive. As cosmetic chemist Colins writes it, "its safety really is beyond any doubt".

Also-called: Titanium Dioxide/Ci 77891;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.

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

Cellulose is an important component of the cell walls of green plants and it's the most abundant natural polymer (big molecule from repeated subunits) on Earth. If the polymer structure is not too big (less than 200 repeated units), cellulose becomes microcrystalline cellulose.

In skin care, it comes as a fine or less fine white powder. The less fine (bigger particle size) version is used as a gentle scrubbing agent (a nice natural, biodegradable alternative to now banned plastic polyethylene) and the ultra fine version is used as a helper ingredient that gives a super-silky, soft touch, reduces tackiness or greasiness and can also be used as a mattifying agent.

Combined with Cellulose Gum, it also works as a nice gelling agent.

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). 

Also-called: CI 77019;Mica | What-it-does: colorant

A super versatile and common mineral powder that comes in different particle sizes. It is a multi-tasker used to improve skin feel, increase product slip, give the product light-reflecting properties, enhance skin adhesion or serve as an anti-caking agent.

It is also the most commonly used "base" material for layered composite pigments such as pearl-effect pigments. In this case, mica is coated with one or more metal oxides (most commonly titanium dioxide) to achieve pearl effect via the physical phenomenon known as interference. 

What-it-does: surfactant/cleansing

We don't have description for this ingredient yet.

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.

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.

Also-called: Fragrance, Parfum | 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.  

Also, if your skin is sensitive, fragrance is again not your best friend. It’s the number one cause of contact allergy to cosmetics. It’s definitely a smart thing to avoid with sensitive skin (and fragrance of any type - natural is just as allergic as synthetic, if not worse!). 

Salicylic Acid - superstar
Also-called: BHA | What-it-does: exfoliant, anti-acne, soothing, preservative
  • It's one of the gold standard ingredients for treating problem skin
  • It can exfoliate skin both on the surface and in the pores
  • It's a potent anti-inflammatory agent
  • It's more effective for treating blackheads than acne
  • For acne combine it with antibacterial agents like benzoyl peroxide or azelaic acid

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.

We don't have description for this ingredient yet.

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

A waxy solid material that helps oil and water to mix together, aka emulsifier. It is derived from the fatty alcohol called stearyl alcohol by ethoxylating it and thus making the molecule more water-soluble.

The end result is a mostly water-loving emulsifier, also called solubilizer that can help to dissolve small amounts of oil-loving ingredients into water-based products. Or it can be combined with more oil-loving emulsifiers (such as its sister, Steareth-2) to create stable emulsions. 

What-it-does: chelating

A handy 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.

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

Also-called: Type of clay | What-it-does: viscosity controlling, absorbent/mattifier, emulsion stabilising

A type of clay that was originally found next to the French village, Montmorillon. Nowadays, Montmorillonite is used almost like a synonym for the most common type of clay, bentonite. Technically bentonite is montmorillonite and additional crystalline structures, or to put it another way, montmorillonite is 100% clean bentonite. 

As for montmorillonite in skincare products, it's used for its magic absorbent properties. It's excellent at instantly sucking up sebum and gunk from the skin and it might even be helpful in treating some rashes or skin irritations (contact dermatitis). But be careful, it can also be drying

What-it-does: moisturizer/humectant, solvent, viscosity controlling | Irritancy: 0 | Comedogenicity: 0
  • It's a helper ingredient that improves the freeze-thaw stability of products
  • It's also a solvent, humectant and to some extent a penetration enhancer
  • It has a bad reputation among natural cosmetics advocates but cosmetic scientists and toxicology experts do not agree (read more in the geeky details section)

Tocopherol - goodie
Also-called: Vitamin E | What-it-does: antioxidant | Irritancy: 0-3 | Comedogenicity: 0-3
  • 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
Read all the geeky details about Tocopherol here >>

Also-called: Soybean Oil | What-it-does: emollient, perfuming | Irritancy: 0 | Comedogenicity: 3

The emollient plant oil coming from the soybean. It is considered to be a nice, cost-effective base oil with moisturizing properties. As for its fatty acid profile, it contains 48-59% barrier-repairing linoleic acid, 17-30% nourishing oleic acid and also some (4.5-11%) potentially anti-inflammatory linolenic acid

Also-called: CI 77861, Tin Dioxide | What-it-does: colorant, abrasive/scrub, viscosity controlling

Far from the tin cans you find in the supermarket, Tin Oxide is mostly used when dealing with so-called effect pigments, tricky composite pigments that can do color travel (change color depending on the viewing angle) or give multiple color effect. 

It's often found alongside Mica (as a base material) and Titanium Dioxide (as a coating) to give a glossy, pearlescent effect. Together, they make up a trademarked technology called RonaFlair Blanace from the German manufacturer Merck. According to their info, this combination can balance out undesirable tones in the skin, making it a popular choice for brightening products and highlighters.

Other than that, CosIng (the official EU INCI database) lists its uses as being a bulking agent (to increase the volume of products), as well as a physical exfoliant or an opacifying agent, but being part of composite effect pigments is a much more common use case.
