Retin A Micro Treatment
When over-the-counter acne treatments aren't doing a thing to resolve your stubborn blemishes, your dermatologist might recommend something stronger. Retin-A Micro, which is derived from vitamin A, might be one topical treatment that he recommends. While there may be some initial side effects, clinical studies prior to approval by the U.S. Food & Drug Administration indicate that Retin-A Micro treatment yielded excellent results in a substantial number of study participants.

Retinoids: A "Cornerstone" in Acne Treatment
-
According to the American Academy of Dematology, topical retinoids resolve mild to moderately severe acne by unclogging pores in the skin, thereby preventing whiteheads and blackheads from forming and causing inflammation. Tretinoin, of which Retin-A Micro is a member, was the first retinoid developed for topical use to treat acne. Earlier tretinoins proved to be too harsh for some patients' skin, but the newer generations of tretinoins such as Retin-A Micro are less irritating. According to the official website, Retin-A Micro uses a "microsphere" technology that reduces redness and irritation, as well as the appearance of a shiny face.
What Studies Show
-
Retin-A Micro is made in two formulations, containing either 0.1 percent or 0.04 percent tretinoin by weight, and is gel-like in texture. Two studies conducted prior to FDA approval indicate that 14 and 19 percent of participants using the 0.04 percent solution achieved excellent results, respectively, compared to five and nine control group participants. While there have been no studies conducted to compare Retin-A Micro 0.04 percent and Retin-A Micro 0.1 percent, there is currently no evidence to suggest that one works better or is safer to use than the other. Participants noted common side-effects, such as dryness, itching, flaking, and redness, during the first two weeks of the study, but these symptoms largely resolved with continued use.

Using Retin-A Micro
-
Retin-A Micro should be applied to clean skin that's been washed with a gentle, non-medicated cleanser, usually in the evening or according to your dermatologist's instructions. Only a pea-sized amount should be used. Dot Retin-A Micro on your forehead, cheeks and chin and gently rub it into the rest of your face with your fingertips.
Caution
-
Acne won't resolve right away with use of Retin-A Micro; according to the official website, some people note improvement in two weeks, but it takes up to seven weeks to see the true benefits of using Retin-A Micro. You might experience continued acne during the initial weeks of therapy, and note dry, inflamed or itchy skin. When using this topical, your skin will be sensitive, so avoiding sunlight, including tanning beds, is necessary, as is wearing a sunblock with a factor rating of at least 15. Also avoid using skin care products that are harsh and drying, such as those that contain alcohol or other medications.
Extra Benefits
-
According to the AAD, those who use retinoids such as Retin-A Micro might get a little extra benefit--reduction of fine lines and wrinkles. A 1988 double-blind study conducted on Retin-A cream, Retin-A Micro's precursor, indicated that all 30 patients who completed a 16-week course of treatment noticed marked improvement on their sun-damaged skin.
