Ingredients explained

Water
Est. %60
Function
Origin
WaterThe most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Dimethicone
Est. %9
Function
Origin
DimethiconeThe most common silicone in skincare. It forms a silky, smooth film on the skin’s surface and can help to prevent water loss. It also aids in wound healing and can treat and soften scars. Dimethicone is considered to be very safe for use.
Homosalate
Est. %5
Function
Origin
HomosalateA synthetic chemical UV filter that protects against harmful UVB radiation.
Octocrylene
Est. %4.1
Function
Origin
OctocryleneA synthetic compound that protects skin against harmful ultraviolet light.
Avobenzone
Est. %3
Function
Origin
AvobenzoneA popular sunscreen that protects against UVA rays, which cause premature aging and skin cancer. Avobenzone degrades after about 30 minutes of sun exposure and becomes ineffective. It is therefore often paired with UV-filter stabilizers such as octocrylene.
Butylene Glycol
Est. %2.5
Function
Origin
Butylene GlycolA clear, colorless liquid humectant that draws moisture to the skin. The humectancy of butylene glycol, owed to its two hydroxyl groups, is quite considerable, although not as powerful as glycerin, which contains three hydroxyl groups.
Propanediol
Est. %2
Function
Origin
PropanediolAn excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.
Glycerin
Est. %1.5
Function
Origin
Glycerin

The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective.

Methyl Methacrylate Crosspolymer
Est. %1.3
Function
Origin
Methyl Methacrylate CrosspolymerA synthetic ingredient that is used for bulking, film-forming, and controlling viscosity. It can absorb large amounts of water and oil and creates a network for other ingredients to live in.
Cyclopentasiloxane
Est. %1
Function
Origin
CyclopentasiloxaneA lightweight, fast-spreading emollient that leaves a very soft and silky after-feel on the skin. Supplied as a clear and colorless liquid, cyclopentasiloxane is often used as a solvent to dissolve other silicones in.
Polymethylsilsesquioxane
Est. %0.3
Function
Origin
PolymethylsilsesquioxaneA type of spherical powder that functions on a ball-bearing effect in which the tiny microspheres roll around on the skin and create lubricity. Polymethylsilsesquioxane offers extra slip to skincare products and makes the skin feel soft and smooth.
Lauryl PEG-9 Polydimethylsiloxyethyl Dimethicone
Est. %0.3
Function
Origin
Lauryl PEG-9 Polydimethylsiloxyethyl DimethiconeA powerful emulsifier with the unique trait of being able to work in both oil- and silicone-based formulas. It can also function as a thickener in low concentrations.
PEG-10 Dimethicone
Est. %0.3
Function
Origin
PEG-10 DimethiconeA polyethylene-based emulsifying ingredient. It has a water-loving portion and an oil-loving portion that help to keep the water and oil phases connected to form an emulsion.
Brassica Campestris/Aleurites Fordi Oil Copolymer
Est. %0.3
Function
Origin
Brassica Campestris/Aleurites Fordi Oil Copolymer
Diethylhexyl Succinate
Est. %0.3
Function
Origin
Diethylhexyl Succinate
Stearic Acid
Est. %0.3
Function
Origin
Stearic AcidA saturated fatty acid found in vegetable butter and animal fats. It is an occlusive moisturizing and emollient ingredient and also helps to maintain the barrier function of the skin.
Silica Dimethyl Silylate
Est. %0.3
Function
Origin
Silica Dimethyl SilylateA synthetic 'filler' powder primarily used as a formula helper. It is added in skincare products to adjust their consistency and thickness.
Calcium Aluminum Borosilicate
Est. %0.3
Function
Origin
Calcium Aluminum BorosilicateA naturally-derived ingredient common in color cosmetics such as powder eyshadows and blush. It provides a light shine and can have colors coated onto it.
Sodium Chloride
Est. %0.3
Function
Origin
Sodium Chloride

You’re definitely familiar with sodium chloride, even if you don’t think you are. It’s table salt! Salt works well with some cleansing ingredients (surfactants) to thicken them into gels. It also acts as a stabilizer for water-in-oil emulsions.

Dimethicone/PEG-10/15 Crosspolymer
Est. %0.3
Function
Origin
Dimethicone/PEG-10/15 CrosspolymerA self-emulsifying surfactant, which means that it can help facilitate the formation of water-in-silicone emulsions. This results in lightweight formulas with a soft finish. It can also act as a film-former and thickener.
Ethyl Ferulate
Est. %0.3
Function
Origin
Ethyl Ferulate
Phenoxyethanol
Est. %0.3
Function
Origin
PhenoxyethanolThe most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
Caprylyl Glycol
Est. %0.3
Function
Origin
Caprylyl GlycolAn emollient that improves product spreadability and offers a silky feel on the skin. It also acts as a preservative booster that improves the efficacy of other preservatives. According to the manufacturer, it is also a humectant moisturizer.
Fragrance
Est. %0.3
Function
Origin
FragranceUnder trade secret law, manufacturers have the right not to disclose what exactly went into the fragrance and use the unspecific word Fragrance or Parfum instead. Many fragrances are highly allergenic.
Ethylhexylglycerin
Est. %0.3
Function
Origin
EthylhexylglycerinA preservative booster derived from glycerin. It is commonly paired with other preservatives to improve their efficacy. Ethylhexylglycerin is also a humectant due to its chemical base of glycerin.
Hexylene Glycol
Est. %0.3
Function
Origin
Hexylene GlycolA multifunctional ingredient that is best known for its use as a solvent. It can dissolve both water-based ingredients and oils. For this reason, it can also function as an emulsifier, allowing oil and water ingredients to mix and remain stable.
Citric Acid
Est. %0.3
Function
Origin
Citric AcidA gently exfoliating AHA that helps to remove the top layer of dead skin cells. In comparison to other AHAs, citric acid has been shown to be one of the least effective. It is also very commonly used as a stabilizing and pH-controlling agent.
EDTA
Est. %0.3
Function
Origin
EDTAA synthetically produced ingredient that binds certain metal ions. It can help prevent product discoloration or poor performance in rinse-off products used in 'hard' water.
PEG/PPG-18/18 Dimethicone
Est. %0.3
Function
Origin
PEG/PPG-18/18 DimethiconeA silicone-based emulsifier that has the ability to create non-sticky and non-greasy formulas.
Dimethicone/Vinyl Dimethicone Crosspolymer
Est. %0.3
Function
Origin
Dimethicone/Vinyl Dimethicone CrosspolymerThis ingredient can refer to several kinds of dimethicone crosspolymers. Like other silicones, it makes products feel slippery and non-greasy but can also increase the thickness or improve the water-resistance of a formula.
Triethoxycaprylylsilane
Est. %0.3
Function
Origin
TriethoxycaprylylsilaneA binding and coating ingredient that allows pigments like iron oxides and mica to disperse better in oily environments. This leads to more vibrant colors.

Simply another name for vitamin E. Tocopherol is a fantastic ingredient and especially beneficial for dry and inflamed skin. It has occlusive moisturizing, emollient, antioxidant, and photoprotective properties.

Sodium Citrate
Est. %0.3
Function
Origin
Sodium CitrateA salt of citric acid that has a salty and tart flavor and is used as a fragrance. It is mildly basic, meaning that its addition to a skincare product can adjust the pH upward.
Lecithin
Est. %0.3
Function
Origin
LecithinA humectant, emollient, and emulsifier best suited for water-in-oil emulsions. Lecithin can come from sunflowers, soy, and eggs. The downside to lecithin is that it causes an extra burden on the formula’s preservative because it is nutritious.
Plankton Extract
Est. %0.3
Function
Origin
Plankton ExtractAn extract from a mixture of various tiny marine animals, algae, seaweeds, and microscopic organisms jointly called plankton. One patent refers to it as a moisturizing humectant ingredient.
