How does the Radiesse dermal filler work?


Quick Answer

Radiesse works in two ways, according to Merz North America. After injection, it immediately provides volume under the skin that fills in creases and lines. Over time, the components of Radiesse stimulate the surrounding tissues to produce more collagen, which provides natural volume to the area and also causes the skin to become thicker and more elastic, smoothing out wrinkles and producing a more youthful look.

Radiesse is composed of calcium hydroxylapatite microspheres suspended in a hyaluronic acid gel, explains Merz North America. The calcium hydroxylapatite microspheres form a scaffold under the skin, says the American Society of Plastic Surgeons. The body uses that scaffold to support the growth of new collagen, forming natural filler in the area. The microspheres are heavy enough that they do not migrate after injection, allowing for precise filling of creases and lines. Over time, the spheres break down into calcium and phosphate, natural components of human bone.

Most dermal fillers in use today are simply composed of hyaluronic acid, notes WebMD. Injections of hyaluronic acid provide volume under the skin, filling in creases and lines and smoothing out the skin. Hyaluronic acid by itself stimulates the skin to produce more collagen but not to the extent that hydroxylapatite microspheres do.

Hyaluronic acid is a glycosaminoglycan that is naturally produced by the human body, says Wikipedia. It is a major component of the extracellular matrix found throughout the body.
