In Arizona can a Cosmotologist train to inject Fillers and/or Botox?

i believe you may be a nurse practitioner considering hiring a cosmetologist to work with you? If so, please don't.  An intimate knowledge of facial anatomy and functional dynamics, as well as pharmacology and disease states of muscle, vessels and nerves is required not only for good results but to prevent blindness and strokes.  This is not an area of medicine that can be learned without years of education and training, as well as extensive experience.  This should be obvious to you if for no other reason than the many unnecessary complications you read about on this website.

Far more important than the technique is the skill and experience of your plastic surgeon. Choose your surgeon rather than the technique and let them explain why one technique may be better than another.  See the below link on some suggestions on finding the most qualified Plastic Surgeon for you.  Always insist on a board certified plastic surgeon.

I am not a lawyer but here is  my understanding:  The scope of practice for an RN, NP or PA would allow them to inject fillers and Botox.  RN's and PA's need to be under the direction of a physician and licensed by the state medical or nursing board. NPs in AZ do not need supervision but do need a license from the nursing board.  Any other configuration constitutes the practice of medicine without a license.  To allow or supervise a cosmetologist (or any non licensed/non medical person) would constitute aiding and abetting the practice of medicine without a license. This has consequences for the injector and the supervisor. Check with the medical board if there is any doubt on who is qualified to legally perform the procedures that you contemplate.
