How to Find the Best Sculptra Injector in Ottawa?

I tried Sculptra and was very, very pleased, however, I do not like the bumps it has left on my chin. I have been told by the dermatologist who did the original Sculptra procedure that the bump risk is no longer a concern as the Sculptra will be diluted more or something like that--cannot remember exactly what she said. However, Sculptra is very unpredictable. How do I find the best doctor who specializes in my city (Ottawa, Ontario, Canada)?
