Ingredients explained

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. 

Expand to read more

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. 

Gluconolactone - superstar
What-it-does: exfoliant, chelating
  • It’s a polyhydroxy acid (PHA), that is often referred to as next generation AHA
  • It gently lifts off dead skin cells form the skin surface making skin smooth and even
  • In the long term it provides anti-aging benefits, like increased skin thickness and decreased wrinkles (though a tad less than even more proven superstar AHAs)
  • It’s a great moisturizer and even helps to repair impaired skin barrier
  • It’s antioxidant, and does not make your skin more sensitive to the sun
  • It can be used even if your skin is very sensitive, rosacea prone or if you are post cosmetic procedure

Glycerin - goodie
Also-called: Glycerol | What-it-does: skin-identical ingredient, moisturizer/humectant | Irritancy: 0 | Comedogenicity: 0
  • A natural moisturizer that’s also in our skin
  • Super common, used for more than 50 years
  • Not only a simple moisturizer but plays an important role in keeping the stuff between our skin cells healthy
  • High-glycerin moisturizers are awesome for treating severely dry skin

Niacinamide - superstar
Also-called: vitamin B3, nicotinamide | What-it-does: cell-communicating ingredient, skin brightening, anti-acne, moisturizer/humectant
  • A multi-functional skincare superstar with several proven benefits for the skin
  • Great anti-aging, wrinkle smoothing ingredient used at 4-5% concentration
  • Fades brown spots alone or in combination with amino sugar, acetyl glucosamine
  • Increases ceramide synthesis that results in a stronger, healthier skin barrier and better skin hydration
  • Can help to improve several skin conditions including acne, rosacea, and atopic dermatitis
Read all the geeky details about Niacinamide here >>

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)

Lactic Acid - superstar
  • 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)
Read all the geeky details about Lactic Acid here >>

What-it-does: solvent

A nice odorless liquid used mainly as a superior solubilizer and efficacy booster for cosmetic active ingredients such as skincare bigshot vitamin C, self-tanning active DHA or the anti-acne gold standard, benzoyl peroxide

Other than that it can also be used in hair care products where it gives a longer-lasting and more uniform coloring. According to a manufacturer, it might even prevent the formation of split ends.

What-it-does: viscosity controlling

A kind of salt that's used as a thickener in cosmetic products. 

Malic Acid - goodie
What-it-does: exfoliant, buffering

Malic acid comes from apple 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 malic 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.

Expand to read more

There is not much research out there about malic acid itself. We could find one comparative study, that compared the effectiveness of glycolic acid, lactic acid, citric acid and malic acid. The first two ones were the winners while malic and citric acid were less effective.

Also-called: Acetum

The thing that you put on your salad with some olive oil. But in a more scientific sense vinegar is usually a 5% solution of acetic acid. It's used in cosmetic products to adjust pH. Larg amounts of vinegar on the skin could be irritating and drying.

What-it-does: chelating

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.

Citric Acid - goodie
What-it-does: exfoliant, 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. 

Expand to read more

There is also some research showing that citric acid with regular use (think three months and 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. 

We don't have description for this ingredient yet.

Also-called: Horseradish Root

Horseradish seems to be a rarely used plant extract with little info about what it's doing in a cosmetic product. Some sources say that it's purifying and stimulating, while others say that it's antibacterial and anti-inflammatory. Paula Begoun thinks that horseradish is an irritant, but she does not cite any sources.

Also-called: Burdock Root | What-it-does: antioxidant, soothing

Burdock root is a goodie plant extract that has anti-inflammatory and antioxidant properties. Also, it has some anti-fungal and seborrhea regulation magic powers that make the ingredient especially useful for greasy and flaky skin and scalp. 

Also-called: Cayenne Pepper Fruit Extract

The extract of cayenne pepper that contains capsaicin. According to manufacturer info it can stimulate the skin blood circulation that can be useful for anti-cellulite or massage products. Be careful with it if your skin is sensitive because it's also a skin irritant

Also-called: Mountain Arnica Extract

A nice yellow flower living in the mountains. It has been used as a herbal medicine for centuries, though its effect on skin is rather questionable. It's most famously used to treat bruisings, but there are some studies that show that it's not better than placebo (source: wikipedia).  Also, some consider it to be anti-inflammatory, while other research shows that it can cause skin irritation. 

Sulfur - goodie

A yellowish element that smells of rotten eggs and it might be familiar to you from the periodic table (has the symbol S in there).  It has a long history of medicinal use thanks to its antifungal, antibacterial and keratolytic activity.   It used to be a very common ingredient in the treatment of inflammation-related skin diseases such as acne, rosacea and seborrheic dermatitis, however, due to its malodorousness, it is less popular nowadays. 

Sulfur's precise mechanism of action is not known, but we do know that its effectiveness depends on its direct interaction with the skin surface, meaning the smaller the particle size, the better the effect. The United States Pharmacopeia lists two types of sulfur, sublimed and precipitated. The latter one has a smaller particle size and counts as a superior version. 

Expand to read more

Sulfur is also a team-player and works well when combined with other anti-acne agents, such as salicylic acid or sodium sulfacetamide. In fact, the combination of 10% sodium sulfacetamide and 5% sulfur is the active ingredient duo of several Rx-only anti-acne products. 

As for the disadvantages, there is the rotten egg smell.  Also in higher concentrations, it might cause a mild burning sensation and dry skin.  If you are new to sulfur, patch testing it first is a good idea. 

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.

What-it-does: preservative

The sodium salt of salicylic acid. CosIng (the official EU cosmetic ingredient database) says that it's a preservative and helps to make the product taste bad (called denaturant), while some manufacturer claims that it has exfoliating properties and is antimicrobial. It's good to know, that the salt of an exfoliant is kind of a neutralised form, so if you want to go for exfoliation stick to the pure acid. 

Serine - goodie

Serine is an amino acid that most often comes to the formula as part of a moisturizing complex. It's a non-essential amino acid (meaning that our body can synthesize it) and serves as a water-binding ingredient.

In general, amino acids are great skincare ingredients that play an important role in proper skin hydration but there is not much info out there about what specifically serine can do for the skin.

Urea - goodie
Also-called: Carbamide | What-it-does: skin-identical ingredient, moisturizer/humectant

Yes, it's the thing that can be found naturally in pee. And in the skin. It is an awesome natural moisturizing factor, aka NMF.  NMFs are important components that help the skin to hold onto water and keep it plump, elastic and hydrated. Urea makes up about 7% of NMFs next to other things such as amino acids (40%), PCA (12%) or Lactate (12%).

What makes urea special, is that it is not only a simple moisturizer, but it is thought to be a "small-molecule regulator of epidermal structure and function" meaning that it has a bunch of extra biological activities. It acts as a mild keratolytic agent (some of its moisturizing action is thought to come from urea's ability to break down bonds in the protein called filaggrin and thus freeing up amino acids in the skin), enhances antimicrobial peptide expression and improves skin barrier function

Expand to read more

Being a mild keratolytic agent and strong moisturizer means that high-percentage (10-40%) urea treatments are found effective in a bunch of skin disorders connected to excessive dryness and malfunctioning skin barrier such as ichthyosis, xerosis, psoriasis, eczema and seborrheic dermatitis.  

Overall, just like glycerin, urea is a real oldie but a goodie, a nice ingredient in any moisturizer.

What-it-does: moisturizer/humectant

It's a sweet tasting sugar substitute that helps your skin to hold onto water when used in cosmetic products. It also helps to thicken up products and give them a bit more slip. 

What-it-does: moisturizer/humectant

The salt form of lactic acid. It works as a moisturizer in skin care products.

Sodium Lactate - goodie

The sodium salt of lactic acid. It's a great skin moisturizer and also used to regulate the pH value of the cosmetic formula. It's a natural ingredient approved by both ECOCERT and COSMOS.

What-it-does: preservative

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.
