Why do you say Sculptra is not permanent? The new created collagen will not go down faster than the existing collagen (Photo)

Results from Sculptra are not permanent.  The Sculptra stimulates tissue thickening and collagen production, but this effect goes away after about 2-4 years.  There are potential treatments that can be done to help with any unwanted Sculptra results, so I would discuss this with the physician who treated you.    

If you are unhappy with your Sculptra treatment; Venus Legacy and 5fu/steroid injections may help reverse the effects. You may also consider other dermal fillers to correct and contour any facial asymmetry. I suggest consulting with a facial contouring expert. Best, Dr. Emer

The results you are showing are solely the injector's poor placement. It was placed too superficially and hence it is noticeable during smiling. Duration of Sculptra has not been studied well. Collagen created can last about 7 years. The 2 year quoted duration is a reference to the FDA trial which was stopped at 25 months. The correction was fairly steady and not falling at that time. I would say that it will last several years at least. 5FU and Kenalog can reduce the effects of the Sculptra. The results aren't permanent but are longer lasting then the oft quoted "2 years".
