Radiesse is different from other facial fillers in many ways. 1) Radiesse not only replenishes lost volume immediately upon injection, but it also stimulates the growth of new collagen for longer lasting results. 2) The results of a Radiesse injection are clinically proven to last for a year, and possibly longer, in many patients. 3) Studies have shown that patients are significantly more satisfied with Radiesse injections in comparison to other facial fillers. 4) It is FDA approved to mix with lidocaine, a local anesthetic, to reduce any injection related discomfort.
