Pinkberry Purify + Brightening Super Clay Mask

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.

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.

A clear, colorless emollient ester (oily liquid from isopropyl alcohol + palmitic acid) that makes the skin nice and smooth. It has very good spreading properties and gives a silky touch to the products.

• It’s the second most researched AHA after glycolic acid
• It gently lifts off dead skin cells to reveal newer, fresher, smoother skin
• It also has amazing skin hydrating properties
• In higher concentration (10% and up) it improves skin firmness, thickness and wrinkles
• Choose a product where you know the concentration and pH value because these two greatly influence effectiveness
• Don’t forget to use your sunscreen (in any case but especially so next to an AHA product)

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, without being heavy or greasy.

Aloe Vera is one of today’s magic plants. It does have some very nice properties indeed, though famous dermatologist Leslie Baumann warns us in her book that most of the evidence is anecdotal and the plant might be a bit overhyped.

What research does confirm about Aloe is that it’s a great moisturizer and has several anti-inflammatory (among others contains salicylates, polysaccharides, magnesium lactate and C-glucosyl chromone) as well as some antibacterial components. It also helps wound healing and skin regeneration in general. All in all definitely a goodie.

The distillate created from different parts of the hazelnut-bush-like magic tree, commonly called Witch Hazel. Hamamelis Virginiana Water is a bit of a sloppy ingredient name as the leaves, the twigs and the bark can be used to create extracts or distillates and the different parts contain different amounts of biologically active components. But what you are getting is probably a nice water with astringent, soothing, antioxidant and antibacterial magic properties.  

We went into great detail about Witch Hazel in cosmetics here, detailing the main biologically active components and how they are different in different parts of the plant. Click here and read more >>

An extremely common multitasker ingredient that gives your skin a nice soft feel (emollient) and gives body to creams and lotions. It also helps to stabilize oil-water mixes (emulsions), though it does not function as an emulsifier in itself. Its typical use level in most cream type formulas is 2-3%.  

It’s a so-called fatty alcohol, a mix of cetyl and stearyl alcohol, other two emollient fatty alcohols.  Though chemically speaking, it is alcohol (as in, it has an -OH group in its molecule), its properties are totally different from the properties of low molecular weight or drying alcohols such as denat. alcohol. Fatty alcohols have a long oil-soluble (and thus emollient) tail part that makes them absolutely non-drying and non-irritating and are totally ok for the skin.

A handy multi-tasker, white to light yellowish oil-loving wax that works very well in oil-in-water emulsions.  It makes your skin feel nice and smooth (emollient),  stabilizes oil-water mixes and gives body to them.

Oh, and one more thing: it's a so-called fatty alcohol - the good, emollient type of alcohol that is non-drying and non-irritating. It is often mixed with fellow fatty alcohol, Cetyl Alcohol, and the mixture is called Cetearyl Alcohol in the ingredient list. 

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.

The fragrant essential oil coming from the flowers of Rose Geranium. Like most essential oils, it contains antioxidant and antimicrobial components, but the main ones are fragrant constituents (like citronellol and geraniol). Be careful with it, if your skin is sensitive. 

The sodium salt form of skincare superstar, vitamin C. If you do not know what the big fuss about vitamin C is, you are missing out and you have to click here and read all the geeky details about it.

Pure vitamin C (aka ascorbic acid, AA) is great and all, but its lack of stability is a big challenge for the cosmetics industry. One solution is to create stable derivatives that can be absorbed into the skin, convert there to AA and do all the magic AA is proven to do (which is being an antioxidant, a collagen booster, and a skin brightener).

A sugar based emulsifier that's especially great for low viscosity lotions or even sprays. It's effective in small amounts, only 1-1.5% is needed to form an emulsion. The resulting cream or lotion has great cosmetic properties with good spreadability and an enhanced soft skin feel. 

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.

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). 

If you have spotted ethylhexylglycerin on the ingredient list, most probably you will see there also the current IT-preservative, phenoxyethanol. They are good friends because ethylhexylglycerin can 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 spreading emollient. 

It's one of those things that help your cosmetics not to go wrong too soon, aka a preservative. It’s not a strong one and doesn’t really work against bacteria, but more against mold and yeast. To do that it has to break down to its active form, sorbic acid. For that to happen, there has to be water in the product and the right pH value (pH 3-4). 

But even if everything is right, it’s not enough on its own. If you see potassium sorbate you should see some other preservative next to it too.

A helper ingredient that helps to make the products stay nice longer, aka preservative. It works mainly against fungi. 

It’s pH dependent and works best at acidic pH levels (3-5). It’s not strong enough to be used in itself so it’s always combined with something else, often with potassium sorbate.

• 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

• 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)

Though it says fruit oil in its name, the rosehip fruit contains the seeds that contain the oil. So this one is the same as Rosa Canina Seed Oil,  or Rosehip Oil, known for its high omega fatty acid content (linoleic acid - 51%, linolenic acid - 19% and oleic acid - 20%) and skin-regenerative properties. 

There is a common misconception that rosehip oil contains vitamin C as the fruit itself does, but vitamin C is a water-soluble vitamin hence it is not contained in the oil. The antioxidant and regenerative properties of the oil probably come from the oil-soluble tocopherols (vitamin E) and carotenoids (pro-vitamin A). Read more here.

Acetyl Hexapeptide-1 is a bit of a special snowflake among peptides as it's not a wrinkle-smoothing, anti-aging active like most of the other ones but it can stimulate pigmentation and melanin production (by interacting with a skin cell receptor called MC1R).

As melanin not only gives the skin its nice tanned color but also works as a natural protection factor, Acetyl Hexapeptide-1, aka Melitane does the same.  It not only boosts a natural or an artificial tan but gives extra protection against UV-induced DNA and free radical damage and protects the skin against UV-caused redness. 

• Works best between a concentration of 5-20%
• Boosts the skin’s own collagen production
• Fades pigmentation and brown spots
• If used under sunscreen it boosts its UV protection
• Extremely unstable and oxidizes very easily in presence of light or air
• Stable in solutions with water only if pH is less than 3.5 or in waterless formulations
• Vit E + C work in synergy and provide superb photoprotection
• Ferulic acid doubles the photoprotection effect of Vit C+E and helps to stabilize Vit C
• Potent Vit. C serums might cause a slight tingling on sensitive skin

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.

We have to start by writing that there are about 900 citrus species in the world, and plenty of them are used to make different kinds of extracts used in cosmetics. This particular one, Citrus Aurantium Dulcis Fruit Extract is a very common ingredient, however, the species "Citrus Aurantium Dulcis" seem to exist only on ingredient lists and the real world calls this guy Citrus Sinensis or, you know, orange. 

To complicate matters further, there are lots of varieties and lots of extraction methods, so it is a bit hard to know what you are getting with this one, but we will try our best to summarize the possibilities.

This awfully long named ingredient is, in fact, a pretty small molecule. It's a tripeptide (a three amino acid peptide)  with molecular weight less than 500 Da, meaning that it's small enough to penetrate nicely and easily into the skin.

It belongs to the "Botox in a jar" type of peptides (similar to Argireline or Leuphasyl) targeting wrinkles caused by facial movements, like laughter lines or crow’s feet. According to the manufacturer's in-vivo (made on real people) studies, 4% Syn-Ake used for 28 days resulted in 21% smoother and 15-20% less wrinkled skin with max values up to 52%. The smoothing effect was measurable on 80% of the volunteers, while the wrinkle reduction effect was evident on 73%.

A very common ingredient that can be found in all 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.

Lonicera Japonica, or Japanese Honeysuckle as normal people call it, is a white-flowered honeysuckle known for being a traditional Chinese medicine. Modern research confirms that the plant has a super complex chemical composition with more than 140 compounds identified with possible anti-inflammatory, antibacterial, antiviral, antioxidative and hepatoprotective activities.

As for Lonicera Japonica Flower Extract in skin care, it can have two main roles. The first one is being an anti-inflammatory and soothing ingredient, probably due to chlorogenic acid, a polyphenol thought to be the main bioactive component of the flower.

Though its name says acid, it's not really an exfoliant. It's a plant extract with some antioxidant properties. Its main thing in cosmetic products is to neutralize the metal ions in the formula (that usually get into there from water) that would otherwise cause some not so nice changes.  It's a natural alternative to sometimes bad-mouthed chelating agents, EDTAs.

If you ever wondered what those little Listerine breath strips were made of, you found your answer! Pullulan is a polysaccharide polymer, which basically means that it’s a big molecule made up of smaller sugar molecule units.

It dissolves in water and can make a thin, elastic, and moisture-absorbing film when spread on the skin that can cause an instant tightening effect. It can also be used as a thickener to get a silicone-like feel and can be used in peel-off masks. Btw, it's made from fungus via fermentation. 

Apple needs no introduction as one of the most common fruits on planet Earth. It's not only a healthy fruit snack, it's also a goodie if you put in all over your face. 

It's loaded with proteins, starch, sugars, acids, vitamins and salts. The sugars (mainly fructose, glucose, sucrose) give apple fruit extract nice moisturizing and smoothing properties, while the acids (mainly malic  and gallic acid) give it mild exfoliant, skin brightening and antibacterial properties. 

Also known as Sugarcane, Saccharum Officinarum is a handy moisturizing ingredient mostly used as a humectant. This means that it can help the skin to attract water and then to hold onto it. 
 
It bears a close relationship to AHA superstar, Glycolic Acid that can be derived from it, so it's often claimed that Sugarcane Extract itself also exfoliates and brightens the skin. We could not find any research studies to back this up, but Saccharum Officinarum very often comes to the formula combined with other acid containing plant extracts trade named ACB Fruit Mix. According to manufacturer data, 5% of the fruit mix increases cellular renewal by 24%, while 4% pure Glycolic did the same by 33%. So maybe, a tiny bit of exfoliation, but if you want proven efficacy, stick to pure acids. 

A big sugar molecule (polysaccharide) that is used as a natural thickening and gelling agent. It is similar to more commonly used Xanthan Gum, and the two are also often combined to create gel formulas or to stabilize emulsions. 

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. 

Thanks to Nivea, Q10 is a pretty well-known ingredient and the fame and Beiersdorf's (the parent company of Nivea) obsession with it are not for no reason. It's an antioxidant found naturally in human cells where it plays a big role in energy production.

In fact, it's so important for energy production that if taken as an oral supplement it has a caffeine-like effect and if taken at night you will probably not sleep very well (so you should take it in the morning). Q10 supplementation is not a bad idea: it not only gives you energy but research also shows that oral Q10 increases the Q10 level of the skin (of course, it decreases with age like pretty much every good thing in the skin) and may help to reduce wrinkles. If you are not for supplements, dietary sources include fish, spinach, and nuts.
