Hi 1) Is Sculptra safe? I read some horror stories about sculptra and how it developed smaller and bigger lumps and those had to be surgically removed. 2. In terms of getting the treatment, is it important to get it done only from a board certified plastic surgeon? or a Nurse Practitioner who is also a National Injectible Trainer would be equally good? What should be the criteria? What should be the minimum qualification of the person who gets to inject those filler in your face? Thanks
