Radiesse is dermal filler made of synthetic calcium hydroxylapatite. The procedure begins with marking the injection sites and cleaning them with an antibacterial agent. The filler is injected carefully using ultra-fine needles and then the injection sites are massaged and the results are evaluated. The filler immediately adds volume to the treated areas and, as the gel is absorbed by the body, it leaves behind microspheres of CaHA. This acts as a scaffold to support the skin’s weakened structure and promote the growth of new collagen.
