Radiesse (Calcium Hydroxyl apatite) is a "biodynamic" filler, meaning that its presence in the skin induces a reaction on the part of the skin to make new collagen. This new collagen has been demonstrated by both biopsies and MRI examination. In general it replaces the gel which dissolves soon after injection and then the implant remains fairly constant for 6-9 months, then slowly fades by 12-14 months in most patients
