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.
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.
Phenyl Trimethicone
What-it-does: emollient
A silicone fluid that gives anonoily, easy to spread emolliencyto the formulas. It is also used as a water repellent additive and to reduce the tackiness and stickiness of otheringredients. It also imparts gloss, softness and better manageability to hair.
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.
Caprylic/Capric Triglyceride
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 andeasy to formulate with. No wonder it’s popular.
Hydrogenated Poly(C6-14 Olefin)
What-it-does: emollient, viscosity controlling
We don't have description for this ingredient yet.
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.
Polyglycerin-3
What-it-does: moisturizer/humectant
Three glycerin molecules attached together. It is a humectant and moisturizer ingredient just like glycerin, but the largermolecular structure penetrates slower into the skin and gives milder, longer lasting moisture.
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

Panax Ginseng Root Extract - goodie
Also-called: True Ginseng, Ginseng, Korean Ginseng | What-it-does: antioxidant, emollient
Atraditional Korean medicine used for more than2000 years. Regarding skin care, its main thing seems to be enhancing skin nutrition and metabolism as a result of improvingblood circulation.
It also contains biologically active components referred to as ginseng saponins (ginsenosides) that have potent antioxidant properties.
Hydrogenated Lecithin - goodie
What-it-does: emollient, emulsifying
It's the chemically chopped up version of normal lecithin. Most often it's used to create liposomes and to coat and stabilizeother ingredients.
Lactobacillus Ferment - goodie
What-it-does: soothing, preservative
Lactobacillus ferment is an interesting probiotic ingredient with some promising properties.
First, according to a 2009 Estee Lauder patent, it’s a DNA repair enzyme and it can help to protect the skin against environmental aggressors.
Second, still according to Estee Lauder research but now from 2012 the ingredient has anti-microbial and anti-inflammatory properties and holds promise in the treatment of acne and rosacea. For the former one 5% was needed to show effectiveness, but for reducing skin sensitivity already 1% showed results.
The anti-acne effect is confirmed also by US manufacturer, Barnet, that says that Lactobacillus ferment is helpful in killing harmful bacteria and creating a healthy balanced microflora. Compared to well-known anti-acne and anti-inflammatory salicylic acid the probiotic worked faster at reducing the size and redness of acne lesions.
It also goes by the trade nameLeucidalLiquid SF and can serve in the formula as a natural preservative.
Bottom line: It’s not the most proven ingredient (yet) but definitely a very promising one especially if you have sensitive skin, acne or rosacea.
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.
Sodium Hyaluronate - goodie
What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0
It’s the - sodium form - cousin of the famous NMF,hyaluronic 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 kindofstephenwrites on reddit "sodium hyaluronate disassociates into hyaluronic acid molecule and a sodium atom in solution".
In spite of this, if you search for "hyaluronic acid vs sodium hyaluronate" you will find on multiple places that sodium hyaluronate is smaller and can penetrate the skin better. Chemically, this is definitely not true, as the two forms are almost the same, both are polymers and the subunits can be repeated in both forms as much as you like. (We also checkedProspector for sodium hyaluronate versions actually used in cosmetic products and found that the most common molecular weight was 1.5-1.8 million Da that absolutely counts as high molecular weight).
What seems to be a true difference, though, is that the salt form is more stable, easier to formulate andcheaper so it pops up more often on the ingredient lists.
If you wanna become a real HA-and-the-skin expert you can read way more about the topic at hyaluronic acid(including penetration-questions, differences between high and low molecular weight versions and a bunch of references to scientific literature).

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.
Pistacia Lentiscus(Mastic) Gum
Also-called: Mastic Gum, PoreAway | What-it-does: absorbent/mattifier
Mustic gum is an aromatic resin coming from the bark of a tree that grows on the Greek island of Chios. It was traditionally used as achewing gum to clean the teeth and freshen the breath thanks to its anti-microbial properties.
As for modern skincare, it is the active ingredient in a skin care complex trade named PoreAway, that is claimed to tightendilated pores and reduce shine. It works by blocking5α reductase type I, an enzyme that has an important role in the sebum-producing process (by converting testosterone to dihydrotestosterone, aka DHT, that is the main sebum producing hormonein the skin).
Do not expect miracles though: according to the in-vivo test conducted by the manufacturer, 2% PoreAway refined pores only by 8% after 14 days and 15% after 28 days. We are not sure if this is a change that you can really feel and see on your skin, or if it's just a "statistically significant change" that can be measured in the lab.
Poncirus Trifoliata Fruit Extract
We don't have description for this ingredient yet.
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.
Lactobacillus Ferment Lysate
We don't have description for this ingredient yet.
Bifida Ferment Lysate - goodie
Bifida Ferment Lysate is a probiotic ingredient that’s used in one of the most iconic serums in the world, the Estee Lauder Advanced Night Repair.Based on manufacturer info it potently protects against UV-induced damage in the skin and helps with DNA repair. An Estee Lauder patent from 2009 also talks about DNA repair activity.
As far as published research goes we could find one promising one. It showed that applying 10% bacterial extract to sensitive, reactive skin helped with better barrier function and decreased skin sensitivity.
Overall, it is definitely a promising ingredient, even for sensitive skin types but not the most proven one (yet).
Vitex Agnus Castus Extract
What-it-does: astringent

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.
Phytosphingosine - goodie
What-it-does: skin-identical ingredient, cell-communicating ingredient, anti-acne, antimicrobial/antibacterial
It's a type of lipid, a so-calledsphingoid base that can be found naturally in the upper layer of the skin. It's found both in "free-form" and as part of famous skin lipids, ceramides.
There is emerging research about Phytosphingosine that shows that it has antimicrobial and cell-communicating properties and is considered part of the skin's natural defense system.
A 2007 study showed thatPhytosphingosine even works againstevil acne-causing bacteria,Propionibacterium acnes and shows promise as a complementing active ingredient in treating acne-prone skin thanks to its anti-inflammatory and antimicrobial activities.
A nice one to spot in the ingredient list. :)
Portulaca Oleracea Extract - goodie
Also-called: Purslane Extract | What-it-does: soothing, antioxidant
Portulaca Oleracea is anice succulent with bright yellow flowers and edible nutritious vegetables. It's a famousplant in Korean traditional medicine to treat infection andirritated skin.
Modern research confirms that it's loaded with skin-goodies: it's the richest green plant source of omega-3 fatty acids (α-linolenic acid), contains NMFs (polysaccharides and amino acids), vitamins (β-carotene), minerals, and antioxidants (yellow betaxanthins and reddish betacyanins). Thanks to all its beneficial components, Purslane Extracthas several magic properties: it's a great anti-inflammatory and antioxidant agent and also has wound healing abilities.
Cetyl Ethylhexanoate
What-it-does: emollient
An odorless and colorless emollient ester (cetylalcohol + ethylhexanoicacid) that gives a velvety and silky feel to the skin. It has great spreadability and a non-oily feel. It's a popular ingredient in makeup removers.
Pentaerythrityl Tetraisostearate
What-it-does: emollient, emulsifying, surfactant/cleansing | Irritancy: 0 | Comedogenicity: 2
A liquid emollient derived from isostearic acidthat gives arich, cushiony skin-feel andunusually high levels of gloss. It also has film-forming abilities but without leaving a sticky residue and it aids long-lasting and water-resistant properties. All this makesPentaerythrityl Tetraisostearate an ideal emollient forlong-lasting protective emulsions, like lip balms.
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.
Glyceryl Stearate
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 calledstearic acid. It can be produced from most vegetable oils (in oils three fattyacidmolecules 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 chemistColins writes it, "its safety really is beyond any doubt".
Acrylates/C10-30 Alkyl Acrylate Crosspolymer
What-it-does: viscosity controlling, emulsion stabilising
Though its long name does not reveal it, this polymer molecule (big molecule from repeated subunits or monomers) is a relative to the super common, water-loving thickener, Carbomer. Both of them are big molecules that contain acrylic acid units, butAcrylates/C10-30 Alkyl Acrylate Crosspolymer also contains some other monomers that are hydrophobic, i.e. water-hating.
This means that our molecule is part water- and part oil-loving, so it not only works as a thickener but also as an emulsion stabilizer. It is very common in gel-type formulas that also contain an oil-phase as well as in cleansers as it also works with most cleansing agents (unlike a lot of other thickeners).
Carbomer
What-it-does: viscosity controlling, emulsion stabilising | Irritancy: 0 | Comedogenicity: 1
A big molecule created from repeated subunits (a polymer of acrylic acid) that magically converts a liquidinto a nice gel formula. It usually has to be neutralized with a base (such as sodium hydroxide) for the thickening to occur and it creates viscous, clear gels that also feel nice and non-tacky on the skin. No wonder, it is a very popular and common ingredient. Typically used at 1% or less in most formulations.
Adenosine - goodie
What-it-does: cell-communicating ingredient
Adenosine is an important little compound in our body that has a vital cell-signalling role. Research on smearing it on our face is also promising and shows so far a couple of things:
- It can help with wound healing
- It’s a good anti-inflammatory agent
- It might even help with skin’s own collagen production and improve skin firmness and elasticity
- It helps with barrier repair and protection
- It might be even useful for the hair helping with hair thickness and hair growth
Tromethamine
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 neutralizeacidic ingredients.
Sodium Stearoyl Glutamate
What-it-does: emulsifying, surfactant/cleansing
An amino acid-based emulsifier that helps water and oil to mix and stay that way. It is considered as natural, environmentally friendly, and hypoallergenic.
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

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.
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!).
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.
