What is calcium hydroxylapatite (CaHA)?
Calcium hydroxylapatite is a mineral compound that occurs naturally in bone and teeth. In Radiesse, tiny CaHA microspheres are suspended in a smooth water-based gel. The gel helps provide volume and lift on the day of treatment, and as it is gradually absorbed, the microspheres act as a scaffold intended to encourage your skin’s own collagen and elastin production. Over time the microspheres are metabolized and cleared by the body, with the goal of leaving the skin looking firmer and more resilient.
