This is a bit of a touchy subject, as you will find injectors ranging from fellowship trained surgeons, non-core cosmetic physicians, general medicine doctors, dentists, physician assistants, nurse practitioners, and registered nurses. In some states, like our neighboring Idaho, even an arsthetician can inject, although most reputable practices don't let that happen. Some nurses are truly great injectors, but there will always be limitations to an injectors knowledge base, based on what their underlying training is. My advice would be, choose your injector based on their reputation, before and after pictures, and expertise. Do not choose an injector because they are less expensive or you are going to get a deal. You are always going to get what you pay for. To ensure you are receiving the highest level of care, seek out a modernly trained, new-school dermatologic surgeon, oculoplastic surgeon, facial plastic surgeon or plastic surgeon who is board certified and fellowship trained in one of these "core four" cosmetic specialties. Membership in organizations like the American Academy of Facial Plastic and Reconstructive Surgery help to identify a highly trained surgeon. Cameron Chesnut #realself500 Physician
