Radiesse is now widely used for the cosmetic treatment of deep facial lines and folds, acne scarring, deep furrows between the brows, other areas of facial depressions, and issues affecting the size and shape of the lips. When injected beneath the skin, the CaHA microspheres are encapsulated or trapped by the body’s collagen fiber, gently lifting and supporting the skin. Radiesse does not require allergy or sensitization testing.
