Does one need to be board certified if injecting fillers, Kybella? Or can a doctor's assistant perform these procedures?

Thank you for your question. It is very important to seek treatment from a board-certified dermatologist. Dermatologists have the thorough knowledge of the anatomy required for injectables and fillers. 

Thank you for your question.  Laws vary from state to state, but in most of the US non-physicians are legally allowed to inject Botox, fillers, and Kybella.  These injectors vary in their qualifications, skills, and the degree of physician supervision under which they practice.  That said, all of these treatments have potentially serious risks and side effects, so it's important to ensure that your injector has knowledge of facial anatomy, extensive experience with cosmetic injections, and understands how to manage any complications in the unfortunate event that they occur.  For this reason, I only recommend seeing board-certified dermatologists, plastic surgeons, facial plastic surgeons, or oculoplastic surgeons for cosmetic injections.  Best of luck!
