natural compound in sebum, precursor to cholesterol
Squalene is a natural organic compound that is a precursor to cholesterol and other steroids. It is found in high concentrations in shark liver oil, but also occurs in olive oil, wheat germ oil, and the human sebum. Squalene is valued for its moisturizing properties and is often used in skincare products to help maintain skin hydration and barrier function.
