Radiesse dermal filler is a strong collagen stimulator composed of calcium and gel. The CAHA microspheres naturally degrade to calcium and phosphate ions, which are metabolized by the body’s normal processes.Over time, the gel is absorbed, and fibroblasts appear. The process of neocollagenesis begins, stimulating the gradual growth of the patient’s own collagen. The collagen that forms results in extended correction and increased patient satisfaction. Clinical results have been shown to last a year or more in many patients.
