Another newer injectable is Sculptra, a polymerized form of lactic acid (a product of sugarcane). Lactic acid polymers have been used for many years to produce absorbable surgical sutures (stitches), which gradually dissolve.
What is Sculptra?
Sculptra is a suspension of small particles of the material; when injected just beneath the skin, Sculptra stimulates production of collagen as it dissolves, adding extra volume to the cheek. Sculptra is usually given in a series of two or three treatments, each spaced several weeks apart. The volume augmentation can take two or more months to be fully evident. The treatment effects are more than additive in that the second and especially the third treatment sessions result in more volume augmentation than the first.
