JUVÉDERM® is a gel injected into areas of facial tissue where moderate to severe facial wrinkles, folds or volume loss occur. It temporarily adds volume to the skin and subcutaneous tissues which may give the appearance of a smoother skin surface and help smooth moderate to severe facial wrinkles and folds. Correction is temporary and touch-up injections are usually needed to maintain optimal correction. Less material may be needed for repeat injections given prior to complete metabolism of previously injected gel. Most patients need one or possibly two treatments to achieve optimal wrinkle smoothing. The results may last as long as nine months to one year with JUVÉDERM®, and up to two years in the cheek area with JUVÉDERM® VOLUMA.
