Also known as: Cholest-5-En-3-Ol

Cholesterol is a critical component of the skin's lipid barrier, comprising approximately 25% of the stratum corneum lipid content alongside ceramides and fatty acids. It is essential for maintaining the lamellar structure of the barrier. Topical cholesterol is used in barrier repair formulations, often combined with ceramides and fatty acids in a 3:1:1 ratio.
