retinoic acid

an oxidized derivative of retinol, believed to be the form of vitamin A that plays a role in the development and growth of bone and in the maintenance of normal epithelial structures. The all-trans isomer is called tretinoin and used as a keratolytic and antineoplastic agent. The 13-cis isomer is called isotretinoin and used as a treatment for acne.
