Are Sculptra Injections Permanent?

How Long Does Sculptra Last?
Sculptra is in a class of its own in terms of facial injectables. The product induces a proliferative response and stimulates collagen production. After a short period, the injected sculptra is gone, only to be left behind by your own collagen.
How long your own collagen will last is dependent on your specific profile. If you continue to damage your skin with poor diet, sun bathing, and stress, the collagen will break down and degenerate at a more advanced rate than someone who adheres to a more skin-healthy lifestyle.
This is not to say that if you are displeased with Sculptra you should damage your skin. It is just a reminder that collagen synthesis and degradation is a byproduct of your own genetics and environment.

The short answer is no, Sculptra injections are not permanent. The results will tend to last approximately 2 years in most patients, although some patients will see benefits for longer. There will be a gradual loss of volume over time as the effects of the product dissipate. 

No, although this product lasts around 2 years, it is not permanent. After being injected, it stimulates the fibroblasts in the dermis to produce your own collagen. This result is natural-looking and gradual, but must be repeated every 1-2 years to maintain the result. After 2 years, the collagen will dissipate and the area will go back to baseline
