Ingredients explained

Water
Est. %65
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.
C14-22 Alkane
Est. %9
Function
Origin
C14-22 Alkane
Dicaprylyl Ether
Est. %6
Function
Origin
Dicaprylyl EtherA fast-spreading and very lightweight emollient. It is used to reduce the tack and oiliness of oil-based formulas and gives the skin a dry, silky after-feel. It is also a great solvent.
Butylene Glycol
Est. %4
Function
Origin
Butylene Glycol

A 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.

Coconut Alkanes
Est. %3
Function
Origin
Coconut AlkanesAn occlusive moisturizing and emollient mixture that is similar to paraffin. It is produced from coconut oil and can allegedly form a soft, non-greasy film on the skin’s surface. It can be used as an alternative to silicones.
Polysilicone-11
Est. %2.5
Function
Origin
Polysilicone-11A synthetic rubber-like substance of the silicone family that has no color or distinct scent. These are large molecules that cannot penetrate the skin but instead create a thin silky film on the skin's surface.
Polyglyceryl-10 Mono/Dioleate
Est. %2
Function
Origin
Polyglyceryl-10 Mono/Dioleate
Polyglyceryl-3 Oleate
Est. %1.5
Function
Origin
Polyglyceryl-3 Oleate
Dimethicone/Vinyl Dimethicone Crosspolymer
Est. %1.3
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.
Glycerin
Est. %1
Function
Origin
Glycerin

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

Cyclopentasiloxane
Est. %0.3
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.
Cocos Nucifera Water
Est. %0.3
Function
Origin
Cocos Nucifera WaterCoconut water from fresh coconuts. It mainly contains water, a bit of coconut oil, sugars, and small amounts of antioxidants.
Glyceryl Caprylate
Est. %0.3
Function
Origin
Glyceryl CaprylateA waxy solid derived from vegetable oils that has emollient and emulsifying properties. It is also known to boost the efficacy of organic acid preservatives by destabilizing the microbe's cell membrane.
Dimethicone
Est. %0.3
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.
Squalane
Est. %0.3
Function
Origin
SqualaneAn occlusive moisturizing and emollient compound that forms part of the skin’s sebum. The main source of squalane had always been shark liver. Now, however, it is manufactured synthetically or derived from plant oils, such as olive and peanut oil.
Glycine Soja (Soybean) Sterols
Est. %0.3
Function
Origin
Glycine Soja (Soybean) SterolsA mixture of phytosterols isolated from soybean oil. Phytosterols, when used in skincare products, have emollient properties and can make the skin feel softer and smoother.
Cetyl Hydroxyethylcellulose
Est. %0.3
Function
Origin
Cetyl HydroxyethylcelluloseA naturally-derived polymer that helps products feel buttery and bouncy and can reduce stringiness in a formula.
Glyceryl Undecylenate
Est. %0.3
Function
Origin
Glyceryl UndecylenateA natural ingredient with a lightweight sensorial profile and the ability to support oil-in-water emulsions.
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.

Function
Origin
Laureth-12
Gellan Gum
Est. %0.3
Function
