retinoic acid

Retinoic acid is a form of vitamin A that plays a crucial role in regulating cell growth, differentiation, and repair in the body. It is naturally produced in the skin and body from vitamin A and is essential for maintaining healthy skin, vision, and immune function. In dermatology, retinoic acid is often used in medications to treat acne and other skin conditions because it helps promote skin cell turnover and prevent clogged pores. It works by signaling cells to mature and behave properly, supporting overall skin health and renewal.
