Dermal Fillers used in our practice includes Restylane, Juvederm and Radiesse. These substances are not actually injected into the dermis, but rather, just beneath it. The dermis is the deep layer of the skin that lies just beneath the epidermis. These “fillers” are used for certain depressed scars, wrinkles, folds and contour irregularities. There are subtle differences between certain fillers based on volume, firmness, palpability, longevity and ease of injection. Certain fillers may be injected throughout the face, while others should only be placed in specific areas.
Chemically, Restylane and Juvederm are nearly identical and are Hyaluronic Acid Gels. Hyaluronic acid is a normal constituent of human dermis and connective tissues. It is typically well-tolerated and there is no possibility for allergic reaction. These products are well tolerated when injected into the vermillion of the lip, at the vermillion border and into fine lines. Radiesse is Calcium Hydroxylapatite and is typically injected into deeper folds such as the nasolabial folds. It is somewhat firmer than hyaluronic acid gels and lasts longer. It is not typically injected into smaller lines or wrinkles.
