Retin-A Micro is the trademark for a topical form of natural vitamin A that contains the active ingredient tretinoin. It's sold in the U.S. under various brand names, including Altinac, Atralin, Avita, Renova, Retin-A Micro Gel, Retin-A and Tretin-X, according to Drugs.com. Some forms of Retin-A Micro are used to treat acne, while others are prescribed to improve the appearance of fine wrinkles, rough skin or skin discoloration.
History
Retin-A has been used as an anti-acne treatment for more than 30 years, according to Linda Nelson, national technical director for Skin Authority. When people who used Retin-A products noticed marked improvements in their overall facial appearance, the U.S. Food and Drug Administration approved the product for cosmetic use as well.
Effects
The acne cycle begins when your body secretes excess oil that accumulates to clog skin pores, according to the American Academy of Dermatology. Bacteria infect the oil plugs, causing inflammation in the form of blackheads, whiteheads, pimples and pus-filled cysts. When you apply a Retin-A product such as Retin-A Micro Gel to acne lesions, it loosens clogged pores and prevents future flare-ups, according to manufacturer Ortho Dermatologics. Linda Nelson says Retin-A also causes thinning of the outermost skin layer, thickening of the underneath layer of skin and increased collagen production. Those changes make wrinkles less noticeable and can even out your skin color and texture.
Benefits
Retin-A products gradually improve your skin appearance, and you can expect to see full benefit after seven weeks of treatment, says Linda Nelson, national technical director for Skin Authority. It's important to continue using Retin-A Micro to prevent further acne blemishes and maintain healthy-looking skin.
Side Effects
Retin-A Micro, like other tretinoin products, also works through a process known as the retinoid effect that creates undesirable side effects. Nelson says your skin may break out more during the first two weeks of use. You might notice reddening similar to a light sunburn, and your skin may peel. However, Retin-A Micro can also cause serious complications, such as excessive redness, dryness, swelling or blistering of the skin where it's applied. Notify your doctor if you have any of these serious side effects or if the temporary mild side effects don't go away.
Tips
It's important to use Retin-A Micro as directed by your health-care provider, according to Ortho Dermatologics. Continue using the product after your skin clears up to stop the development of further acne blemishes and improve facial appearance.
