Who Can Give Juvederm Injections? What Licensure is Needed?

In New York, an injection such as a filler must be done by a physician, registered nurse or physician's assistant provided that the latter by supervised by a physician.
These laws vary by state.

The laws vary from state to state, but most states allow nurses to inject under the supervision of a doctor.
Here in Washington state, the medical board is in the process of spelling out exactly what this supervisory relationship needs to be. In general, injections should be in a medical facility where the name of the supervising physician is clear.
In my view, training and experience are the most important things. Some nurse injectors are actually trainers for physicians who are just starting, and some doctors sort of dabble in it while a nurse may do it all day.

In California, those with a medical license such as physician, nurse practitioner, physician assistant, and registered nurse are permitted to perform cosmetic injections with Botox and cosmetic dermal fillers. Complying with what is referred to as a "good faith exam" is fulfilling current regulations. Although these practitioners are within their scope of practice to do so, this does not imply that they are well-trained and experienced with current techniques. As seen by the many consumer questions and feedback on this website, going to a physician of any specialty does not necessarily guarantee an experienced, skilled injector. When choosing an injector, be certain that they involve you in the treatent plan, the learning process, show photos of actual patients, and stay current with their knowledge base and skills.
