Retinol
Retinol is the classic form of vitamin A. When retinol is applied to the skin, it is converted to retinaldehyde and then to the active form, retinoic acid, the form that all types of vitamin A must convert to before becoming effective on the skin. Once active, retinol can deliver all of the youthful benefits we associate with vitamin A.
