Juvéderm, one of the newest of the so-called “injectable fillers,” is used by cosmetic, dermatological and plastic surgeons to soften deep folds and reduce wrinkles in the faces of patients. The substance is chemically closely related to the facial filler Restylane; both are largely comprised of hyaluronic acid, a substance normally found in the skin, muscles, and tendons of mammals. Approved in June 2006 by the U.S.
