Ingredients explained

Water
Est. %60
Function
Origin
The 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.
Cyclopentasiloxane
Est. %9
Function
Origin
A 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.
Isododecane
Est. %6
Function
Origin
An emollient derived from petroleum with high spreadability. It is often used as a replacement for oils and silicones because it leaves no residue behind on the skin. When a product is labeled as “oil-free” it may contain isododecane instead of heavier oils.

Est. %4
Function
Origin
A silicone-based powerful emulsifier that helps to create lightweight and pleasant feeling lotions and creams.
