A good rule of thumb is that you will need one vial for each decade of life.So, a woman in her forties will need four vials; a woman in her sixties will need six vials.Sculptra is typically performed over several sessions. In a typical session, two vials are injected. However, if a patient is very volume depleted, I may choose to do three vials; if a patient doesn't need as much, I may only do 1 vial.This is a rough guide. And some percentage of patients will require more total vials to get the desired effect and others less. In our practice, Sculptra is ~$800/vial, and a typical session is ~$1600. So, a series of three sessions will run about $4800. This is a big investment, but Sculptra does provide the most "bang for the bunk," in terms of the amount of volume that it provides and the length of time the volume lasts. Their initial study showed that patients were just as satisfied at 2 years with their wrinkle reduction. I do recommend maintenance of 1-2 vials annually or bi-annually.
