Water
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.
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.
Propylheptyl Caprylate
What-it-does: emollient
Acrystal clear, oily liquid that makes your skin nice and smooth, aka emollient. It is fast-spreading and leaves a luxurious,silky-soft after-feel. It is also ideal for sunscreen products as it can enhance the solubility of crystalline UV filters.
Propanediol
Also-called: Zemea | What-it-does: solvent, moisturizer/humectant
Propanediol is a natural alternative for the often usedand 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 efficacyor to influence the sensory properties of the end formula.
Hexyl Laurate
What-it-does: emollient
A fast spreading emollient ester (hexyl alcohol + lauric acid) that's usedin water in oil emulsions or in water-free formulas. It gives a light skin feel.
Acrylates Copolymer
What-it-does: viscosity controlling
A big polymer molecule that has a bunch of different versions and thus different uses. It can act as afilm former, asathickening agent, or it canincrease the water-resistance in sunscreens. It is alsoused toentrappigments/inorganic sunscreens within a micron size matrix for even coverage and easy application.
Caprylyl Methicone
What-it-does: emollient
A clear, colorless, low viscosity, volatile (does not absorb into the skin but rather evaporates from it) silicone fluid that has excellent spreadability and leaves a light, silky and smooth feel on the skin.
According to manufacturer info, its big advantage is that it's compatible both with other silicones and with natural plant oils, so it's a great ingredient to formulate products with good-sounding, consumer-pleasing vegetable oils but still maintain a cosmetically elegant, non-greasy and non-tacky feel.

Lauryl Polyglyceryl-3 Polydimethylsiloxyethyl Dimethicone
What-it-does: surfactant/cleansing
We don't have description for this ingredient yet.
1,2-Hexanediol
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 perfumesin 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.

Fragrance/Parfum - 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.
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!).
Magnesium Sulfate
Also-called: Epsom salt | What-it-does: viscosity controlling
A helper ingredient that is used as a bulking and viscosity controlling agent. It is alsoan emulsion stabilizer in water-in-oil emulsions, where water droplets are dispersed in the continuous oil phase and not the other way round.
It can also be used as a heat generating agent in water-less formulas as it has an instant heat-generating chemical reaction with water.
Butylene Glycol
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.
It’s an ingredient whose safety hasn’t been questioned so far by anyone (at least not that we know about). BG is approved by Ecocert and is also used enthusiastically in natural products. BTW, it’s also a food additive.
Chlorella Vulgaris Extract
We don't have description for this ingredient yet.
Disteardimonium Hectorite
What-it-does: viscosity controlling
An organic derivative of hectorite clay, Disteardimonium Hectorite is used as a viscosity controller - it thickens up formulations to make them less runny.
It’s most popular use in cosmetics is in sunscreens, under the trademarked name Bentone 38 from Elementis. According to the manufacturer info, it is a real multi-tasker, including the ability to prevent pigments settling during storage, stabilizing a formula for longer,creating a light and smooth skin feel andenhancing the water-resistance of sunscreen formulas.

Polyhydroxystearic Acid
What-it-does: emulsifying
A so-called dispersant or dispersing agent that's used in inorganic (titanium dioxide/zinc oxidebased) sunscreens or in make-up products to help to distribute the pigments nicely and evenly on the skin. It's also claimed to increase the UV absorption of the sunscreen formula as well as to reduce the annoying white cast left behind by inorganic sunscreens.
Fructose - goodie
What-it-does: moisturizer/humectant
Fancy name for fruit sugar. It has nice water-binding properties and helps to keep skin hydrated.
Caprylic/Capric Triglyceride
What-it-does: emollient

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 naturallyin 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 thatthe lowest concentration to prevent evil acne-causing P. acnesgrowth of lauric acidis over 15 times lower than that of gold standard anti-acne ingredient benzoyl peroxide.
Though the studies are only in-vitro(made in the lab, not on real people), and it also has a high comedogenicity index, itmightbe worth a try if you are prone to inflamed acne (the type that's caused by P. acnes bacteria).
Vinyl Dimethicone/Methicone Silsesquioxane Crosspolymer
What-it-does: viscosity controlling
This bamboozling INCI name is given to aspherical silicone powder that has an elastic silicone rubber inner partand a harder silicone resin outer part.
It gives formulas a uniquely soft, silky feeling,and has a mattifying and soft focus effect. It is available in different particle sizes and the larger the particle the more line/pore filling effect the powder has.
Isopropyl Myristate
What-it-does: emollient, perfuming | Irritancy: 3 | Comedogenicity: 3-5
A clear, colorless oil-like liquid that makes the skin feel smooth and nice (aka emollient) and it does so without it being greasy.
What's more, it can evenreduce the heavy, greasy feel in products with high oil content.It's also fast-spreading meaning that it gives the formulaa good, nice slip. Itabsorbs quickly into the skin and helps other ingredients to penetrate quicker and deeper.
Thanks to all this, it's one of the most commonly used emollients out there. There is just one little drawback:it has ahigh comedogenicindex (5 out of 5...), so it might clog poresif you're prone to it.
Isostearic Acid
What-it-does: surfactant/cleansing, emulsifying
A liquid fatty acidcreated from oleic acid. It's claimed to have great odour, thermal and oxidation stability and is great for the stabilization of pigments and mineral particles in oils and solvents. It's quite popular in foundations.
Lecithin - goodie
What-it-does: emollient, emulsifying
A very common ingredient that can be found inall 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.
Xanthan Gum
What-it-does: viscosity controlling, emulsion stabilising
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-calledrheology 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).
Polyglyceryl-3 Polyricinoleate
What-it-does: emulsifying, viscosity controlling
A plant based ingredient that helps water to mix with oil (aka W/O emulsifier).It's especially good for soft to low-viscosity water-in-oil emulsionswith non-greasy, pleasant skin feellike lip balms or thick body butters.

- 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

Ethylhexylglycerin
What-it-does: preservative, deodorant
If you have spottedethylhexylglycerinon the ingredient list, most probably you will see there also the current IT-preservative,phenoxyethanol. They are good friends becauseethylhexylglycerincan 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 spreadingemollient.
Althaea Rosea Flower Extract
We don't have description for this ingredient yet.
Rosmarinus Officinalis (Rosemary) Leaf Extract - goodie
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, andanti-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.
Centella Asiatica Extract - goodie
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 calledasiaticoside, madecassoside, asiatic and madecassic acid (also called centellosides).
One of the biological activities of thecentellosides isto be able to stimulate GAGs (glycosaminoglycans - polysaccharides that are part of the liquidy stuff between our skin cells), and especially hyaluronic acid synthesis in our skin. This is probably one of the reasons why Centella Asiatica Extract has nice skin moisturizingproperties that was confirmed by a 25 people, four weeks study along with Centella's anti-inflammatory effects.
Madecassoside can also help in burn wound healing through increasing antioxidant activity and enhancing collagen synthesis. Asiaticoside was shown to increase antioxidant levels on rats skin when applied at 0.2%.
Centella Asiatica also often shows up in products that try to treat cellulite or striae. Of course, it cannot make a miracle but it might have some effect via regulating microcirculation and normalizing the metabolism in the cells of connective tissues.
Bottom line: Gotu Kola is a great plant ingredient with proven wound healing, anti-inflammatory,and antioxidant properties. Nice to spot on any ingredient list.
Limonene - icky
What-it-does: perfuming, solvent, deodorant
A supercommon and cheap fragrance ingredient. It's in many plants, e.g. rosemary, eucalyptus, lavender, lemongrass, peppermint and it's the main component (about 50-90%) of the peel oil of citrus fruits.
It does smellnice but the problemis that it oxidizes on air exposure and the resulting stuff is not good for the skin. Oxidizedlimonene cancause allergic contact dermatitis and counts asa frequent skin sensitizer.
Limonene's nr1 function is definitely being a fragrance component, but there are several studies showing that it's also a penetration enhancer, mainly for oil-loving components.
All in all, limonene has some pros and cons, but - especially if your skin is sensitive -the cons probably outweigh the pros.
Linalool - icky
What-it-does: perfuming, deodorant
Linalool is a super common fragrance ingredient. It’s kind of everywhere - both in plants and in cosmetic products. It’s part of 200 natural oils including lavender, ylang-ylang, bergamot, jasmine, geranium and it can be found in 90-95% of prestige perfumes on the market.
The problem with linalool is, that just like limoneneit oxidises on air exposure and becomes allergenic. That’s why a product containing linalool that has been opened for several months is more likely to be allergenic than a fresh one.
A study made in the UK with 483 people tested the allergic reaction to 3% oxidised linalool and 2.3% had positive test results.
Geraniol - icky
What-it-does: perfuming
Geraniol is a common fragrance ingredient. It smells like rose and can be found in rose oil or in small quantities in geranium, lemon and many other essential oils.
Just like other similar fragrance ingredients (like linalool and limonene) geraniol also oxidises on air exposure and becomes allergenic. Best to avoid if you have sensitive skin.
