I had 4 vials of Sculptra . I see no difference. Do you think its going to work or not?

Because Sculptra is a stimulating agent, it normally does take a series of treatments to obtain the best result.  Without seeing you or pictures of you before your treatments, it is difficult to know if you might have been a good candidate for Sculptra or not.  For patients that do not need drastic improvement, it can still take 2-4 treatments to get the desired result.  If a patient's starting point is more severe, it could take 3-6 sessions to get to the final result.  It also will take 1-2 months after a Sculptra treatment to see the effect of that particular treatment session.  I would encourage you to discuss your concerns with the physician who treated you.  

Sculptra works by stimulating collagen production around the areas of injection.  This buildup causes an increase in volume in the area which then helps lift the skin and minimize wrinkles.  This buildup takes time however and it is gradual.  You should see full results by 3 months after the injection.  My best advice to you would be to look at your presculptra photos and compare them to the way you look today.  Oftentimes, becuase the results are gradual over a lond period of time, it is difficult to see the results without the comparison.  If you still don't see any difference, discuss your results with your physician.
