RADIESSE injectables use CaHA gel which provides immediate results and stimulates production of collagen and elastin for continued long-term benefits. On its own, the gel fills spaces of the face and hands. Then CaHA, a compound that is naturally metabolized by the body, produces collagen and elastin during the breakdown process – ultimately taking the place of the gel. Due to its bio-stimulating properties, RADIESSE treatments are known to last at least a year, with clients often experiencing continued improvements even after the one year mark.
