What is hyaluronic acid? What is hyaluronic acid used for?
Restylane is a gel of hyaluronic acid produced by bacteria and used for treating facial wrinkles and folds. It is classified as a medical device. Hyaluronic acid is a substance that is normally produced by the body; it is what gives skin its volume and fullness. The hyaluronic acid in Restylane is called non-animal stabilized hyaluronic acid (NASHA) because it is not derived from animal sources. When Restylane is injected into wrinkled skin it adds fullness and reduces the prominence of the wrinkles in the previously wrinkled area. Hyaluronic acid also attracts and binds water, and this also helps maintain fullness in the area of injection. The benefit of hyaluronic acid may last for six months or longer. Restylane was approved by the FDA in December 2003.

Smoking, light skin type, hairstyle, the way you dress, your occupational and recreational habits, and heredity are all factors that promote wrinkling. Medical treatments for wrinkles include antioxidants, moisturizers, alpha-hydroxy acids, and vitamin A acid. Cosmetic procedures that treat wrinkles include dermabrasion, microdermabrasion, glycolic acid peels, laser resurfacing, Botox, and fillers.
