For treatment of moderate to severe wrinkles around the nose and mouth, Juvéderm® XC is an injectable hyaluronic acid dermal filler gel which adds volume and smooths skin. Hyaluronic acid is a naturally occurring substance found in the human body, functioning to bind water and hydrate tissue. This substance becomes less abundant during the aging process. Juvéderm® XC can help to replace lost volume and wrinkles resulting from aging. The product contains lidocaine, an anesthetic agent, to improve comfort during treatment. Results are visible immediately and last approximately six months.
