JuvedermTM is a non-animal based injectable filler made in the laboratory. It is made of hyaluronic acid - a material that is in the joints and bodies of all living things. Hyaluronic acid is also the main ingredient of Restylane. It is a complex sugar that maintains its three dimensional shape in the body by attracting and holding large numbers of water molecules. Among its many natural functions, hyaluronic acid maintains the volume of the skin, keeps skin hydrated and maintains shape. As we age, we lose hyaluronic acid from the skin and it loses its volume and structure. Injecting JuvedermTM into skin folds and wrinkles replaces that structure and volume.
