Sculptra stimulates collagen production to deliver natural looking results gradually. Collagen is what gives the face a youthful looking appearance. As we age collagen levels deplete, about 1% is lost per year. Deep within the skin Sculptra works to help restore lost collagen. It is the only FDA-approved biodegradable injectable. It is PLLA-(poly-L-lactic acid) a collagen biostimulator that works deep in the skin to improve its inner structure to smooth facial wrinkles, such as smile lines and nasal labial folds. Patients who have had treatment done agreed that the treatment results still looked natural 2 years after their last treatment with a 94% approval rating.
