Hydroxyapatite Calcium Application

Calcium hydroxyapatite (CaHA) is a well-established collagen stimulator. In recent years, it has been increasingly used in hyperdiluted form as a bio stimulatory agent rather than a volumizing filler to improve skin quality and firmness in both facial and corporal areas.

Following the successful expansion of noninvasive rejuvenation procedures for the face, a demand for nonsurgical rejuvenation options for non-facial areas is also growing. Radiesse (Merz North America, Raleigh, N.C.) is a biocompatible and biodegradable bio stimulatory filler containing calcium hydroxyapatite (CaHA) microspheres that can stimulate the endogenous production of collagen. It is a unique product that provides both volume replacement and collagen biostimulation as a primary mechanism of action.
