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.
Ethylhexyl Palmitate
What-it-does: emollient | Irritancy: 0 | Comedogenicity: 2-4
A super common, medium-spreading emollient ester that gives richness to the formulaand a mild feel during rubout. It can be a replacement for mineral oil and is often combined with other emollients to achievedifferent sensorial properties.
Dipropylene Glycol
What-it-does: solvent
A clear, colorless liquid that works as a solvent and viscositydecreasing ingredient. It also has great skin-moisturizing abilities.

Olea Europaea (Olive) Fruit Oil - goodie
Also-called: Olive Fruit Oil | What-it-does: antioxidant, emollient | Irritancy: 0 | Comedogenicity: 0-2
You probably know olive oil from the kitchen as a great and healthy option for salad dressing but it's also agreat and healthy option to moisturize and nourish the skin, especially if it's on the dry side.
Similar to other emollient plant oils, it's loaded with nourishing fatty acids: oleic is the main component (55-83%), and also contains linoleic (3.5-20%) and palmitic acids (7-20%). It also contains antioxidant polyphenols, tocopherols (types of vitamin E) and carotenoids and it's one of the best plant sources of skin-identical emollient, Squalene.
Overall, a great option for dry skin butless so for acne-prone or damaged skin.
Squalane - goodie
What-it-does: skin-identical ingredient, emollient | Irritancy: 0 | Comedogenicity: 1
It seems to us that squalane is in fashion and there is a reason for it. Chemically speaking, it is a saturated (no double bonds) hydrocarbon (a molecule consisting only of carbon and hydrogen), meaning that it's a nice and stable oily liquid with a long shelf life.
It occurs naturally in certain fish and plant oils (e.g. olive), and in the sebum (the oily stuff our skin produces) of the human skin. As f.c. puts it in his awesome blog post, squalane's main things are"emolliency, surface occlusion, and TEWL prevention all with extreme cosmetic elegance". In other words, it's a superb moisturizer that makes your skin nice and smooth, withoutbeing heavy or greasy.
Another advantage of squalane is that it is pretty much compatible with all skin types and skin conditions. It isexcellent for acne-prone skin and safe to use even if you have fungi-related skin issues, likeseborrhea or fungal acne.
The unsaturated (with double bonds) and hence less stable version ofSqualane is Squalene, youcan read about it here >>
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.
Butyrospermum Parkii (Shea) Butter - goodie
Also-called: Shea Butter | What-it-does: emollient
Unless you live under a rock you must have heard about shea butter. It's probably the most hyped up natural butter in skincare today.It comes from the seeds of African Shea or KariteTreesand used as a magic moisturizer and emollient.
But it's not only a simple emollient, it regenerates and soothes the skin,protects it from external factors (such as UV rays or wind) and is also rich in antioxidants (among others vitamin A, E, F, quercetin and epigallocatechin gallate). If you are looking for rich emollient benefits + more, shea is hard to beat.
Ceramide NP - goodie
Also-called: Ceramide 3 | What-it-does: skin-identical ingredient
One of the many types of ceramides that can be found naturally in the upper layer of the skin. Ceramides make upabout 50% of the goopy stuff that's between our skin cells and play a super important role in having a healthy skin barrier and keeping the skin hydrated. It works even better when combined with its pal, Ceramide1.
We wrote way more about ceramides at ceramide 1, so click here to know more.
Camellia Sinensis Leaf Water
We don't have description for this ingredient yet.
Helianthus Annuus (Sunflower) Seed Oil - goodie
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, beautifulyellow flower during the summer - or you do all of these and probably even more. And by even more we mean putting it all overyour 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 evidencethat 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.
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 withfatty 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.
Glycine Soja (Soybean) Oil - goodie
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.

Rubus Idaeus (Raspberry) Fruit Extract - goodie
Also-called: Raspberry Extract | What-it-does: antioxidant, soothing, astringent
Raspberry is one of the colorful berries that’s not only delicious but contains many biologically active, healthy compounds. It has polyphenols including anthocyanins and ellagitannins that have antioxidant and anti-inflammatory properties.
According to skin care expert Paula Begoun, it’s antibacterial as well but due to its tannin content it can cause also irritation to the very sensitive skinned.
Chamomilla Recutita (Matricaria) Flower Extract - goodie
Also-called: German Chamomile Flower Extract | What-it-does: soothing, antioxidant | Irritancy: 0 | Comedogenicity: 0
Chamomileprobably needs no introduction as it's one of the most widely used medicinal herbs. You probably drink it regularly as a nice, calming cup of tea and it's also a regular on skincare ingredient lists.
Cosmetic companies use it mainly for its anti-inflammatory properties. It contains the terpenoids chamazulene and bisabolol both of which show great anti-inflammatory action in animal studies. On top of that chamomile also has some antioxidant activity (thanks to some other active ingredients called matricine, apigenin and luteolin).
Though chamomile is usually a goodie for the skin, it's also not uncommon to have anallergic reaction to it.
Camellia Sinensis Seed Oil
Also-called: Green Tea Seed Oil | What-it-does: moisturizer/humectant
We don't have description for this ingredient yet.
Sodium Chloride
Also-called: Salt | What-it-does: viscosity controlling
Sodium chloride is the fancy name of salt. Normal, everyday table salt.
If (similar to us) you are in the weird habit of reading the label on your shower gel while taking a shower, you might have noticed that sodium chloride is almost always on the ingredient list. The reason for this is that salt acts as a fantastic thickener in cleansing formulas created with ionic cleansing agents(aka surfactants) such as Sodium Laureth Sulfate. A couple of percents (typically 1-3%) turns a runny surfactant solution into a nice gel texture.
If you are into chemistry (if not, we understand, just skip this paragraph), the reason is that electrolytes (you know, the Na+ and Cl- ions) screen the electrostatic repulsion between the head groups of ionic surfactants and thus support the formation of long shaped micelles (instead of spherical ones) that entangle like spaghetti, and viola, a gel is formed. However, too much of it causes the phenomenon called "salting out", and the surfactant solution goes runny again.
Other than that, salt also works as an emulsion stabilizer inwater-in-oil emulsions, that is when water droplets are dispersed in the outer oil (or silicone) phase. And last but not least, when salt is right at the first spot of the ingredient list (and is not dissolved), the product is usually a body scrub where salt is thephysical exfoliating agent.
Sodium Citrate
What-it-does: chelating, buffering
A little helper ingredient that is used to adjustthe pH of the product. It also helps to keep products stay nice longer by neutralizingthe metal ionsin the formula (they usually come from water).
Caprylyl/Capryl Glucoside
What-it-does: surfactant/cleansing

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.
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

Caprylyl Glycol
What-it-does: moisturizer/humectant, emollient, deodorant
It’s a handy multi-tasking ingredient that gives the skin a nice, soft feel. At the same time, it also boosts the effectiveness of other preservatives, such as the nowadays super commonly used phenoxyethanol.
The blend of these two (caprylyl glycol + phenoxyethanol) is called Optiphen, which not only helps to keep your cosmetics free from nasty things for a long time but also gives a good feel to the finished product. It's a popular duo.
Disodium EDTA
What-it-does: chelating
Super common little helper ingredient thathelps 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.
It is typically used in tiny amounts, around 0.1% or less.
Phenoxyethanol
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.
Citric Acid
What-it-does: 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 monthsand 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.
Tocopheryl Acetate
Also-called: Vitamin E Acetate | What-it-does: antioxidant | Irritancy: 0 | Comedogenicity: 0
It’s the most commonly used version of pure vitamin E in cosmetics. You can read all about the pure form here. This one is the so-called esterified version.
According to famous dermatologist, Leslie Baumann while tocopheryl acetate is more stable and has a longer shelf life, it’s also more poorly absorbed by the skin and may not have the same awesome photoprotective effects as pure Vit E.
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.
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.
