This question is actually right up my alley since I am a national trainer for Sculptra. What I can tell you is that the company itself will only train core aesthetic physicians (Plastic Surgeons, Facial Plastic Surgeons, and Dermatologists). Once these physicians are trained, they are then allowed to purchase the actual product. From here, however, the physician can choose to perform the injections themselve or delegate them to a physician extender (e.g. nurse or PA) depending upon state laws.
The most important question to ask before you have any type of injection is the training and the experience of the person who will be performing the actual injections. This is critical. I can tell you from personal experience that injector skill varies widely so make sure you are comfortable before moving forward with any facial injectable.
