what is tretinoin

Tretinoin is a medication used to treat acne, sun-damaged skin, fine wrinkles, dark spots, and rough skin on the face caused by the damaging rays of the sun. It is a prescription-strength topical cream or gel that is also known as retinoic acid, which is the generic name for synthetic vitamin A. Tretinoin works by affecting the growth of skin cells, promoting peeling of affected skin areas, and unclogging pores. It can speed up the life cycle of skin cells, making them divide faster and die faster, so newer, healthier cells can take their place. Tretinoin is sold under many different brand names, including Retin-A, Altreno, Atralin, Avita, Refissa, and Renova. It is usually used daily at bedtime, and the directions on the prescription label should be followed carefully. Tretinoin controls acne but does not cure it, and it works best when used within a skin care program that includes protecting the treated skin from the sun.
