Radiesse (CaHA)
Radiesse is an injectable made of calcium hydroxylapatite (CaHA) microspheres in a gel. It provides immediate support and stimulates collagen over time, improving firmness, fine lines and skin quality. It can be used undiluted for volume or diluted as a skin booster. Treatment takes about 20 minutes with numbing cream and no downtime.
