Cholesterol
Cholesterol (CAS 57-88-5) is a lipid naturally found in the outer layer of the skin, where it makes up approximately 25% of the intercellular matrix. Together with ceramides and fatty acids, it plays a vital role in maintaining a healthy skin barrier. In cosmetics it functions as an emollient, emulsifier, skin conditioner, stabilizer, and viscosity controller.
