Although I love Sculptra as a facial volumizer, it requires a different mindset than the average filler in terms of expectations. One of the most critical aspects about this product (L-poly Lactic Acid) is patient education and understanding the product. Most patient require 2-3 treatment sessions spaced by 4 weeks, which generally correlates with 4-6 vials. In circumstances of severe volume loss, this may require additional treatment sessions. The degree of correction after the 1st treatment session will disappoint the uneducated patient. Most patients see appreciable results 4-6 weeks after the 2nd or 3rd treatment. Sculptra requires more finesse and knowledge of facial anatomy than standard fillers, so choose your injector wisely.
