What is Retinol?

Retinol is the ‘active’ form of fat-soluble Vitamin A. It is a type of retinoid, which is a class of compounds that includes retinol, retinoic acid, retinaldehyde, and retinyl esters. Vitamin A is required for a number of biological processes including embryo development, for night vision, and low light vision as well as cell differentiation. Vitamin A is primarily stored in the body (especially in the liver) as retinol or retinyl esters.
