Retin-A (also known as Renova or Tretinoin) is a topical prescription cream used in the treatment of acne. Retin-A is made from vitamin A, a fat-soluble vitamin that is absorbed through the intestines and stored in the liver. Vitamin A is important to maintaining healthy skin, mucous membranes, the intestinal lining, organs, immune system and the suppression of tumor growth.

Retin-A helps acne by exfoliating the skin's outer layer which helps to loosen the matter in blocked pores, and reduces the formation of blackheads, whiteheads and other acne lesions. It also increases blood vessel development and cell nutrition, decreases clogged pores and makes cells divide faster. It affects the depletion and dispersion of melanin and thickens and strengthens the skin tissues.

Side effects are usually mild, and may include darkening or lightening of the skin, burning, dryness, itching, peeling, redness, and stinging. These symptoms are common with patients with sensitive skin. The symptoms can be controlled by adjusting the frequency of application.

It is very important that you inform your doctor of any medications you are currently taking before using Retin-A. Pregnant or breastfeeding mothers are advised not to use Retin-A. Retin-A should also not be used if the patient is taking other drugs that increase sensitivity to sunlight, including certain antibiotics suchas Cipro, Noroxin, and tetracycline, tranquilizers such as Thorazine and Mellaril, sulfa drugs such as Bactrim and Septra, and Thiazide drugs (water pills) such as Diuril and HydroDIURIL Other skin care regimes should not be combine with Retin-A treatment, as Retin-A can also interfere or have adverse interactions with certain ingredients used in other topical solutions, such as benzoyl peroxide, sulfur, Resorcinol, and Salicylic acid.

RETIN-A MICRO is a topical prescription medicine used in the treatment of acne. It uses a unique Microsponge® system designed to minimize the irritation commonly experienced with the high strength Retin-A. The microspheres are round microscopic particles made of synthetic polymer, suspended in a water-based gel. These particles hold the Retin-A medication in reserve, allowing the skin to absorb small amounts of Retin-A over time. This helps to minimize skin irritation. The microspheres harmlessly remain on top of the skin until washed off; they do not penetrate the skin barrier.

RETIN-A MICRO is currently available in two concentrations, 0.04% and 0.1%. Your doctor or dermatologist can decide which one is right for you.
