What happens after you stop using Sculptra after several years?

Treatment with Sculptra can produce results that last 2-4 years.  If further treatments are not done to maintain the result, the effect will gradually fade and the fullness produced will be lost.  Your face should return to more or less what it looked like before the Sculptra.  

Sculptra produces collagen which will last for 2 to 3 years and then you are back to your baseline. It is a very good option to maintain your facial volume. RegardsDr. J

Thank you for your question.  Sculptra is a great option for subtly adding volume to the face - I have used it for a number of my patients after face lift procedures with excellent results.  Sculptra is different from most other dermal fillers, in that it works by gradually stimulating your body to produce more collagen over the course of several months.  The results can last for up to 2-4 years.  That said, all of our faces naturally start to lose a little bit of fat and collagen every year after the age of about 30 - this process is accelerated by other factors, such as sun exposure and smoking.  
The collagen stimulated by Sculptra is no different - without maintenance treatments, the effects of Sculptra will gradually wear off with time.  Sculptra will not accelerate the aging process or cause more volume loss in any way - your face will just gradually start to look the way it would without fillers.  This is why I generally recommend that my Sculptra patients return for maintenance treatments every year or so to maintain their results.  Best of luck!
