Sculptra works differently than other injectables. It doesn't affect muscle movement like neuromodulators. It doesn't plump tissue by tethering to water molecules. Sculptra is in a league of its own as a collagen-stimulating injectable. To achieve the best results from this treatment, you may need three to four sessions. Scheduled 6-8 weeks apart, each Sculptra session prompts an increase in collagen production that continues to boost tissue regeneration over a period of months.
