Tretinoin is a medication used to treat acne and sun-damaged skin. It can’t erase deep wrinkles, but it can help improve the appearance of surface wrinkles, fine lines, and darks spots.
Tretinoin is also known as retinoic acid. It’s the generic name for synthetic vitamin A. It’s sold under many different brand names. Retin-A is one of those brand names, which shouldn’t be confused with retinol.
