Sculptra requires a series of treatments to achieve adequate results for most skin defects.The number of treatments required varies from 2-6 treatments at 4-6 week intervals depending on skin health and goals in order to achieve the best result. Deep defects may require 4-6 treatment sessions; persons with lesser skin defects can often be treated with as few as 2 sessions. The volume of Sculptra injected at each session is dependent upon the size of the defect being corrected. Single treatments every 1-3 years are recommended to maintain results due to the natural loss of tissue volume due to aging. The effect of Sculptra is slow and gradual, as your skin forms collagen around the product crystals. The best results are seen about three months after the final treatment.
