Looking to restore volume and improve skin texture with natural results? Sculptra works over time to do just this! How much do you need? 1 vial per decade of your age — age 40, that’s 4 vials; age 50, that’s 5 vials, etc. I inject the vials over 3 treatments generally, 1 month apart. FDA approved to last 2 years. I recommend 1 touch up vial per year after initial treatment.
