Radiesse is a dermal filler/collagen stimulator consisting of Calcium hydroxylapatite microspheres suspended in a gel carrier mainly composed of water and glycerine. RadiesseTM is highly biocompatible. Calcium hydroxylapatite is the main mineral component of bone and teeth, which consists of calcium and phosphate ions that occur naturally in the body. FDA approved in 2006.
Radiesse is injected into the skin. The gel carrier acts as an instant filler, providing immediate correction. As the gel carrier is absorbed (within 8-12 weeks), the calcium hydroxylapatite microspheres act as a scaffold and stimulate the production of new collagen in and around them.
Eventually, the microspheres degrade into calcium and phosphate ions and are removed from the body in a natural process of elimination.
It is expected to last 9-24 months; sometimes, the duration may be shorter or longer than expected. It will always degrade over time, and you will return to your pre-treatment state without further treatment.
