The single most common compliance failure in medical spas is not a bad outcome from a treatment. It is a provider performing a procedure they are not legally authorized to perform in that state — often with the practice owner's full knowledge and without malpractice coverage that would pay out if something goes wrong.

Scope of practice in aesthetic medicine is not a single rule. It is a stack: federal classification of the treatment, state medical practice act provisions, state nursing and PA practice acts, board of medicine advisory opinions, and facility licensing requirements. Every layer varies by state. An RN who can inject Botox under a standing order in Georgia may not be able to do the same in California without a physician's direct examination of the patient first. An NP who owns and operates independently in Arizona would need a collaborative practice agreement and physician oversight in Florida.

This article maps the major variables that determine who can do what in a med spa, organized so a practice owner can identify which questions to ask — and which state board to ask them of — before staffing a treatment schedule.

The Starting Point: Aesthetic Procedures Are the Practice of Medicine

Virtually every state has concluded that aesthetic procedures involving injectables, energy-based devices, medical-depth chemical peels, and prescription-strength topicals constitute the practice of medicine. This means the procedure must be performed by — or delegated by — a licensed physician (MD or DO), and in some states a nurse practitioner or physician assistant acting within their authorized scope.

The Illinois IDFPR stated this explicitly in its December 2024 memo: physicians licensed to practice medicine "have, within their scope of practice, the ability to operate a medspa, including performing cosmetic procedures which affect the living layers of skin, and to prescribe and administer drugs, including Botox and weight loss medication injections." The memo further confirms that these procedures must be performed under a physician-patient relationship.

Georgia's Composite Medical Board is equally direct: "These procedures are considered the practice of medicine. Botulinum toxin is a dangerous drug and soft tissue fillers are medical device implants approved by the FDA."

New Mexico's Medical Board issued a 2025 policy stating that "any injection or tissue-penetrating procedure (Botox, fillers, microneedling, chemical peels) must be performed by a licensed medical provider" — and that cosmetologists or estheticians may not use their non-medical license to perform these procedures unless operating as medical assistants under direct physician supervision and written protocols.

Nurse Practitioner Practice Authority: The Three Tiers

Nurse practitioner scope of practice falls into three nationally recognized categories, and the tier determines whether an NP can independently own and operate a med spa.

Full practice authority (27 states + DC and territories)

In these states, NPs can evaluate patients, diagnose, order and interpret tests, and initiate treatment including prescribing medications under the exclusive authority of the state board of nursing. No physician collaboration or supervision agreement is required.

States include Alaska, Arizona, Colorado, Connecticut, Delaware, Hawaii, Idaho, Iowa, Kansas, Maine, Maryland, Massachusetts, Minnesota, Montana, Nebraska, Nevada, New Hampshire, New Mexico, New York, North Dakota, Oregon, Rhode Island, South Dakota, Utah, Vermont, Washington, and Wyoming, plus the District of Columbia, Guam, and the Northern Mariana Islands.

Implication for med spa owners: In these states, an NP with full practice authority can typically own and operate a med spa independently, performing injectables, laser treatments, and other aesthetic procedures without a physician on staff — though some states still require a medical director for facility licensing purposes. Several states have expanded NP practice authority in recent years.

Reduced practice authority

In reduced practice states, NPs can perform most of their scope without physician supervision but face at least one limitation — typically around independent practice ownership, prescribing certain medications, or practicing without a collaborative agreement.

States include Alabama, Arkansas, Illinois, Indiana, Kentucky, Louisiana, Mississippi, New Jersey, Ohio, Pennsylvania, West Virginia, and Wisconsin.

Implication for med spa owners: An NP in Illinois, for example, can own a medspa under specific entity structures, and APRNs with full practice authority can serve as medical directors. But the Illinois memo makes clear that the practice must still comply with entity restrictions under the Medical Practice Act. In Pennsylvania, NPs must maintain a collaborative practice agreement with a physician and are subject to regular reviews.

Restricted practice authority

In restricted practice states, NPs must work under physician supervision for their entire scope of practice. Career-long supervision, delegation, or team management by another health provider is required.

States include California, Florida, Georgia, Michigan, Missouri, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, and Virginia.

Implication for med spa owners: NPs in these states cannot independently own or operate a med spa without physician involvement. The MSO/PC structure is common here: the NP operates the business side through an MSO, while a physician owns the professional entity that provides medical services.

California's evolving landscape

California is a special case. Under Assembly Bill 890, NPs who qualify as "104 NPs" — those who have practiced as a 103 NP in good standing for at least three years (or 4,600 direct-patient-care hours) — may practice independently without standardized procedures beginning in 2026. NPs with a Doctor of Nursing Practice may count doctoral clinical hours toward the 4,600-hour requirement. However, as of 2026, the scope of independent 104 NP practice in medical aesthetics is still being defined by the Board of Registered Nursing, and the settings in which a 104 NP may practice without standardized procedures are limited to specific group practice environments. For med spa purposes, most California NPs still operate under physician supervision requirements.

Physician Assistants

PAs practice under physician supervision in all states, but the nature of that supervision varies:

  • General supervision means the physician is available by phone or electronic communication but need not be on-site.
  • Direct supervision means the physician must be on-site and immediately available.
  • Personal supervision means the physician must be in the room.

In Georgia, PAs can inject toxins and fillers with a board-approved job description and additional duty request. In California, PAs perform aesthetic procedures under physician supervision, and the supervising physician must have examined the patient or be satisfied that a properly delegated prior examination occurred. In most states, PAs cannot independently own a med spa but can be employees or contractors of the physician-owned entity.

Registered Nurses

RNs are the backbone of most med spa injection practices, but their authority to inject is entirely delegated — it comes from the supervising physician's order or protocol, not from their nursing license alone.

Key rules by state:

  • Georgia: RNs can inject with appropriate training and a written order from a physician. The physician does not have to remain on-site while the RN injects pursuant to a written order.
  • California: RNs may administer Botox and fillers under physician supervision. The supervising physician must have examined the patient. Medical assistants may not perform these injections under any circumstances.
  • New Jersey: RNs may administer specific neuromodulator injections or non-ablative laser sessions, but only pursuant to a detailed, physician-signed protocol. Direct supervision is required.
  • Illinois: RNs may perform delegated medical procedures under the supervision of a licensed physician. The IDFPR memo emphasizes that delegation requires proper training and documented physician oversight.
  • Iowa: The medical director or another qualified practitioner must provide direct, in-person, on-site supervision for at least four hours each week and remain within 60 miles when not on-site.
  • New Mexico: RNs can perform aesthetic procedures within their scope, but delegation to unlicensed staff is prohibited except to trained, certified medical assistants under direct physician supervision.

Licensed Practical Nurses

LPNs occupy an ambiguous position in aesthetic medicine. Their scope is narrower than RNs, and most states either prohibit or severely restrict their ability to inject:

  • Georgia prohibits LPNs from injecting toxins and fillers.
  • California prohibits LVNs (the state's equivalent) from performing these procedures.
  • Texas allows LPNs to inject if properly trained and delegated under physician judgment, though this is uncommon.
  • Louisiana is unusual in allowing LPNs to administer Botox for cosmetic purposes when specific conditions are met.
  • Florida generally prohibits LPNs from administering injectables, as their scope does not include invasive procedures.

The safest approach: assume an LPN cannot inject Botox or fillers unless your state nursing board has issued a specific advisory opinion or declaratory statement explicitly permitting it. When in doubt, restrict injection privileges to RNs and above.

Estheticians, Cosmetologists, and Medical Assistants

This is where the most compliance failures occur. In no U.S. state may an esthetician or cosmetologist independently inject Botox, administer dermal fillers, or operate medical-grade lasers under their cosmetology or esthetics license.

However, in some states, these individuals can perform certain medical procedures when functioning as medical assistants under direct physician supervision and written protocols. The key distinction is the capacity in which they are acting:

  • New Mexico's 2025 policy allows trained, certified medical assistants to perform limited non-invasive procedures (including laser/IPL treatments) under direct physician supervision and written protocols — but explicitly prohibits them from injecting, penetrating tissue, placing IVs, or exercising medical judgment. Cosmetologists and estheticians "must not perform medical spa procedures such as lasers, IPL, injectables, or microneedling" unless operating as medical assistants under these conditions.
  • Illinois prohibits individuals from holding themselves out as a cosmetologist or esthetician while performing a service delegated by a licensed physician. The IDFPR memo states that "an individual may not indicate in any manner that he or she is licensed under the Barber, Cosmetology, Esthetics, Hair Braiding and Nail Technology Act while performing delegated medical procedures."
  • Georgia is explicit: "Physicians may not delegate this procedure to medical assistants, and this is defined as Unprofessional Conduct. Injection of botulinum toxin and soft tissue fillers does not fall within the scope of practice for estheticians."
  • Arizona revised its advisory opinion in January 2025, permitting licensed aestheticians and cosmetologists to perform certain medical aesthetics procedures under the supervision of a licensed independent practitioner with appropriate training — but therapeutic medical procedures remain outside their scope and must be performed by an appropriate medical professional.

Ownership Restrictions: The CPOM Layer

Separate from who can perform procedures is who can own the entity that employs them. The Corporate Practice of Medicine (CPOM) doctrine, enforced in a majority of states, prohibits non-physicians from owning or controlling medical practices.

States with strict CPOM enforcement that require physician ownership of the clinical entity: California, Texas, New York, Illinois, Ohio, New Jersey, and others. In these states, the common structure is a physician-owned Professional Corporation (PC) paired with a non-physician-owned Management Services Organization (MSO).

States without CPOM or with weak enforcement: Some states do not enforce CPOM or have carved out exceptions. In full-practice-authority NP states, NPs can typically own the practice entity directly.

Oregon's 2025 change: Oregon SB 951, signed into law June 2025, prohibits MSOs and their principals from owning or controlling professional medical entities, closing loopholes that previously allowed unlicensed entities to influence medical practices. CPOM restrictions take effect January 2026 for new MSOs and January 2029 for existing arrangements. The law creates a private right of action for physicians and is likely to be watched by other states.

Laser and Energy Device Rules

Laser regulation adds another layer. In many states, operating a medical laser is classified as the practice of medicine regardless of who is pressing the button.

  • Georgia requires certified laser practitioners (Level 1 or 2) under the Georgia Cosmetic Laser Services Act. Estheticians may not legally perform IPL or laser procedures.
  • Illinois states that "the use of lasers is the practice of medicine, and excludes the use of lasers from the practice of cosmetology and esthetics." Procedures involving FDA-classified medical devices must be performed by a licensed physician or delegated to a person functioning as an assistant under physician oversight.
  • Arizona permits certified laser technologists to operate laser devices under the supervision of a licensed independent practitioner with medical or surgical training.

How to Build a State-Compliant Staffing Matrix

For each med spa location, build a written matrix that maps:

  1. Every procedure offered (Botox, fillers, lasers, chemical peels, microneedling, IV therapy, etc.)
  2. Every provider type on staff (MD/DO, NP, PA, RN, LPN, MA, esthetician, laser tech)
  3. Whether that provider type can perform that procedure under state law
  4. What level of supervision is required (on-site, available by phone, chart review only)
  5. What written documentation is required (standing orders, collaborative practice agreement, delegation protocol, job description, training certification)
  6. Who the supervising physician is and whether they meet the state's medical director requirements

Cross-reference this matrix against the state medical board's advisory opinions and the state nursing board's scope of practice guidelines. Many boards publish decision trees that answer specific "can an RN inject Botox?" questions. Update the matrix annually or whenever you add a new procedure or provider.

Why This Cannot Be a One-Time Exercise

State scope of practice laws change regularly. California's AB 890 is redefining NP independence. Oregon's SB 951 is tightening CPOM. Illinois issued a comprehensive med spa memo in December 2024 that clarified previously ambiguous delegation rules. Arizona revised its nursing board advisory opinion on aesthetic procedures in January 2025.

A staffing matrix that was compliant when you opened may be non-compliant today. The practice owner's responsibility is to monitor regulatory updates — or retain healthcare counsel who does this proactively — and adjust before a board action forces the adjustment retroactively.
