Also known as: Skin Cholesterol
Cholesterol is a critical component of the skin's lamellar bodies alongside ceramides and fatty acids. The ideal molar ratio for barrier repair is approximately 1:1:1 (ceramides:cholesterol:fatty acids). Topical cholesterol helps restore the lipid matrix of the stratum corneum, reducing transepidermal water loss. Often used in barrier repair formulations targeting eczema and dry skin.
Comedogenicity ratings are based on the rabbit ear assay model. Individual skin responses vary. See our article on comedogenicity ratings for context.
