Retinoic acid is a metabolite of vitamin A, essential for various biological processes in the body. It plays a crucial role in cell growth, differentiation, and development, particularly in the skin and eyes. Retinoic acid is often used in dermatology to treat acne and reduce signs of aging due to its ability to promote skin cell turnover. In addition to its dermatological uses, retinoic acid is vital for embryonic development and maintaining healthy vision. It works by binding to specific receptors in cells, influencing gene expression and cellular functions. Its importance in both health and medicine makes it a significant compound in biochemistry and pharmacology.
