Retin-A, a vitamin-A derivative also known as tretinoin, is a prescription-only medication available as a cream or gel. Originally approved by the Federal Drug Administration to treat acne, Retin-A has several other uses. Retin-A can cause skin irritation and sun sensitivity. If you experience these side effects, discontinue use and consult your doctor.
Acne Treatment
Retin-A helps keep pores from clogging, preventing the development of blackheads and whiteheads, according to the Mayo Clinic. The FDA approved Retin-A to treat acne in 1971. Retin-A causes the skin to regenerate cells more quickly. Cells reproduce rapidly enough that pimples don't have time to form.
Smooths Wrinkles
The same cell-rejuvenation process that makes Retin-A effective against acne also smooths wrinkles and eliminates fine lines. Retin-A also encourages collagen production, which plumps skin and gives it a smoother, softer appearance. Everyday Drugs.com reports most people see wrinkled reduction after six to eight weeks of regular use of Retin-A.
Hyperpigmentation Reduction
Retin-A use can reduce or eliminate areas of uneven pigmentation caused by sun damage or aging. The San Francisco State University Student Health Center reports that 2/3 of people who used Renova, a form of tretinoin, for six months reported a reduction in hyperpigmentation caused by sun damage.
Hair Restoration
Retin-A increases the effectiveness of the hair restorative drug minoxidil. Regular application of Retin-A decreases the thickness of the scalp and allows minoxidil to better penetrate the skin, according to the University of Maryland Medical Center.
Wart Removal
Flat warts, caused by various forms of the human papilloma virus, respond to treatment with Retin-A. Retin-A causes the warts to peel off in layers until they eventually disappear.
