Injectable Fillers
Juvederm® is a biodegradable, but long-lasting injectable filler composed mostly of hyaluronic acid, a material found in the skin, muscles, and tendons in the body. The natural form of hyaluronic acid is liquid, a substance that the body metabolizes quickly. In order to make Juvéderm, the liquid form of hyaluronic acid is cross-linked so that the individual chains of the acid bind together, transforming the substance into a gel.
As an injectable gel, hyaluronic acid adds structure and volume to the lips, facial wrinkles and folds. Similarly, Radiesse is a long-lasting injectable that is used for the treatment of facial wrinkles and folds. Its composition, however, is quite different. Radiesse is made of substance called calcium hydroxylapatite or CaHA, a gel that contains small calcium microspheres.
