Overview

Despite the big fuss being made about cholesterol in our diets and bloodstream, the cholesterol in our skincare plays an indisputably beneficial role in barrier repair (together with ceramides and fatty acids). Around 25% of the skin’s lipid layer is made up of cholesterol, and you can find it in the membrane of every single cell in our body.

Purified cholesterol is obtained mainly from animal sources and takes on the form of a white powder or white, solid flakes. It is very oily and emollient. Cholesterol also serves as a stabilizer, thickener, and emulsifier in skincare products.
