Retin-A is a prescription medication used to treat mild to moderately severe acne. It belongs to a group of medications called topical retinoids. These are medications derived from vitamin A. The treatment begins with the cleansing of the surface of the skin before it is applied topically as a cream or gel. A moisturizer is also applied to soothe the skin and prevent dryness. Retin-A normalizes skin cell behavior while also producing faster growth and regeneration. The treatment renews the skin and reduces the look of wrinkles and skin discoloration.
