Also known as: Tretinoin
Tretinoin is used to treat acne or other skin diseases as determined by your doctor. It works partly by keeping skin pores clear.
One of the tretinoin creams is used to treat fine wrinkles, dark spots, or rough skin on the face caused by the damaging rays of the sun. It works by lightening the skin, replacing older skin with newer skin, and slowing down the way the body removes skin cells that may have been harmed by the sun. Tretinoin works best when used within a skin care program that includes protecting the treated skin from the sun. However, it does not completely or permanently erase these skin problems or greatly improve more obvious changes in the skin, such as deep wrinkles caused by the sun or the natural aging process.
This medicine is available only with your doctor's prescription.
This section provides information on the proper use of a number of products that contain tretinoin. It may not be specific to Retin-A Micro. Please read with care.

Before applying tretinoin, wash the skin with a mild soap or cleanser and warm water by using the tips of your fingers. Then gently pat dry. Do not scrub your face with a sponge or washcloth.
