Juvéderm is a safe, FDA-approved formula that lasts up to one year. It contains lidocaine, a local anesthetic, to minimize the mild discomfort that is sometimes associated with receiving an injection. The injection of hyaluronic acid-a naturally occurring substance in the skin that adds volume and hydration-is administered directly to targeted areas to reduce the appearance of wrinkles and folds while also smoothing the skin. It is an effective technique for restoring a youthful plumpness to the skin.
