- License sets scope. A training certificate does not expand it.
- RNs carry out orders; they do not write them. Injections are a delegated act after a prescriber’s exam.
- NPs have full practice authority in Arizona, within certification, training and competence.
- PAs work under a physician arrangement set by the PA board and the practice agreement.
- Always confirm with the board. Rules and interpretations change.
Start with the license, not the certificate
Arizona has no injector license, and a training certificate does not expand your scope. What you may do in aesthetics depends on the license you hold, the orders and protocols you work under, and your own training and competence. This guide lays the four main license types side by side.
It is a plain-language overview of general principles, not a ruling on any specific situation. Boards interpret their rules, and rules change, so confirm with the relevant board.
The matrix
| Question | RN | NP | PA | MD / DO |
|---|---|---|---|---|
| Can perform neuromodulator and filler injections | Yes, as a delegated act under a prescriber’s order, if trained and competent | Yes, within scope and competence | Yes, within the scope set by the practice arrangement | Yes, within competence |
| Can write the treatment order | No. Carries out a prescriber’s order | Yes, within scope and certification | Yes, as the PA board’s rules and the practice arrangement allow | Yes |
| Performs the good-faith exam | No. A prescriber does it | Yes | Generally yes, per the practice arrangement | Yes |
| Needs another clinician’s oversight in practice | Yes: a prescriber’s order and protocols | Arizona is a full practice state for NPs; the practice may still use a medical director | Yes: an arrangement with a physician under PA board rules | Not required for their own practice; remains responsible for the care they delegate or order |
| What a certificate changes | Nothing about scope. It shows training. Your license and the orders in place set what you may do. | |||
Where a cell says “as the arrangement allows,” the answer depends on board rules and the specific agreement. Check the current rules for your license before you rely on it.
RNs
An RN does not prescribe. Aesthetic injections are performed as a delegated medical act under a prescriber’s written order, after the prescriber’s good-faith exam. The Board of Nursing publishes advisory opinions on related practice. See the ASBN advisory opinion definition and Level II vs. Level III. Our RN vs. NP earnings guide covers the income difference.
NPs
Arizona is listed by AANP as a full practice authority state, so NPs may evaluate, diagnose and prescribe within their certification and scope. A.R.S. § 32-1601 defines the registered nurse practitioner. Full practice authority does not mean unlimited scope: you must act within your population focus, your training and your competence. See full practice authority, prescriptive authority and FNP-BC vs. FNP-C.
PAs
PAs practice under the Arizona Regulatory Board of Physician Assistants and an arrangement with a physician. What that arrangement requires, and how it applies to aesthetic procedures, is set by the board’s current rules and by the practice’s own agreement. Confirm it with the board and your employer before you add services.
MD and DO
Physicians have the broadest scope, and still carry the standard of care for what they delegate or order. A physician who serves as medical director takes on oversight duties; see the medical director definition and MD vs. DO vs. NP as medical director.
What about dentists, estheticians and medical assistants?
Dental scope for injectables is set by the Arizona State Board of Dental Examiners, so confirm current rules there. Estheticians and medical assistants do not hold a license that permits injection by itself; see our guides on estheticians and the injector pathway.
- Assuming a certificate changes what your license allows.
- Treating “full practice authority” as meaning no limits.
- Working from a standing order that does not name your license type.
- Skipping the good-faith exam because the patient is a repeat.
