Radiesse is a filler that is injected deeper than HA products. It contains calcium hydroxylapatite (CaHA) that is naturally found in human connective tissue. CaHA is suspended in a carboxymethylcellulose gel that is absorbed over time – 30% CaHA and 70% gel. Meanwhile, fibroblasts and collagen form around the CaHA particles – a process known as neocollagenesis. Because of its white color, it cannot be injected superficially as it would be visible. As deep volume filler, it provides some advantages over HA products.
The most common areas treated are cheeks, areas under the eyes (but not as close to thin lid skin as HA products), nasolabial folds, jowls, corners of mouth, temples, and even hands. Radiesse provides deep subdermal augmentation but cannot be used superficially for individual wrinkle treatment as HA products. It lasts between 9 and 18 months resulting in high patient satisfaction.
Treatment is performed as a brief office procedure. After anesthetizing the area with local anesthetic, a tiny canula is used to inject Radiesse under the skin. Our office premixes Radiesse with a local anesthetic adding to better tolerance of injections. Mild discomfort may be experienced, but many patients describe this procedure as painless.
Side effects are swelling and bruising which are usually minimal. If bruising occurs, special cover-up makeup can be used. The areas of injection are tender for 2 – 3 days.
