What Are Sculptra & Radiesse?
Sculptra and Radiesse are injectable biostimulators. Sculptra is poly-L-lactic acid, which is reconstituted in advance so it is ready at the appointment. Radiesse is calcium hydroxylapatite, diluted far beyond the concentration used as a filler so it disperses through the tissue. Neither one adds volume on the day the way hyaluronic acid filler does. Both prompt the skin to make its own collagen where support has gone, and that collagen is what produces the change, which is why the difference appears over months. Firmness builds in the dermis for weeks before it shows in a photograph. In Galderma's trials, Sculptra Aesthetic patients were followed for two full years once their series was complete.
