Prevelle is a single cross-linked product made from hyaluronic acid and is designed for a superficial injection level. Prevelle contains lidocaine which reduces discomfort during the procedure. The procedure begins with the cleansing of the marked injection sites with an antibacterial agent. The number of injections given depends on the area being treated and the depth of the wrinkle. Prevelle adds volume to the skin and minimizes the appearance of wrinkles. The procedure typically lasts 30 minutes to one hour.
