What is true in every state

A med spa is a medical practice
Injectables, lasers, and most aesthetic treatments are the practice of medicine everywhere. A licensed physician has to stand behind the medical care, whatever the ownership structure.
Someone qualified examines the patient first
A good-faith exam by a physician, NP, or PA, confirming the treatment is appropriate, is expected before treatment nearly everywhere. A patient cannot simply be handed to an injector.
Estheticians do not inject
Injecting neurotoxins or fillers is outside an esthetician's or cosmetologist's scope in every state. Injecting is done by physicians, NPs, PAs, or RNs acting under proper delegation.
Delegation and supervision are the real rules
Who may perform what, and how closely a physician must supervise, is where states differ most. The license of the person treating, not the spa's name, decides what is legal.

Reviewed June 2026. This is general information, not legal advice. Medical-spa regulation changes and turns on the specifics of your services, your staff's licenses, and your corporate structure. Confirm the current rules with your state medical and nursing boards and a healthcare attorney before you open or restructure.

Can a non-physician own a med spa?

In much of the country, not directly. A med spa offering injectables or laser treatments is a medical practice, and most states apply the Corporate Practice of Medicine doctrine, which holds that only a licensed physician can own one. A non-physician takes part through a management-services organization (an MSO) that owns the non-clinical side and contracts with a physician-owned entity for the medical care. California, New York, New Jersey, Texas, Illinois, and Colorado are the strictest about this.

Other states let a non-physician own the business more directly, though a physician still has to stand behind the treatments. Arizona and Florida are the two most often cited as easier on ownership. The lookup above gives the rule for a specific state, and flags the ones where the sources genuinely disagree. The rest of this page covers the parts that follow from ownership: the medical director, the good-faith exam, and who may inject.

Do you need a medical director for a med spa?

In practice, almost always. In a Corporate Practice of Medicine state, the physician owner or a designated medical director is the person legally standing behind every treatment the spa performs. Even where a separate medical-director requirement is not spelled out, the good-faith-exam and delegation rules mean a physician has to be involved in the care.

A med spa with no physician behind it is out of compliance even where the written rules are light, because the exam, the prescribing, and the delegation all run through a physician. The medical director is not a figurehead: they are responsible for protocols, delegation, and the standard of care, and regulators hold them to it.

What is a good-faith exam, and is telehealth enough?

A good-faith exam is an assessment by a physician, nurse practitioner, or physician assistant that confirms a treatment is appropriate for the patient before it is performed. It is the gate every patient passes through, and it is expected before treatment in nearly every state. It cannot be replaced by the injector doing their own quick assessment.

Where states differ is the format. Many allow the exam to be done by telehealth, which is what lets a remote NP or physician clear patients for a spa. Some still expect it in person, at least for the first visit. The lookup flags which applies, but confirm the current rule before you build a telehealth exam into your workflow.

Who can inject Botox and filler at a med spa?

Physicians, nurse practitioners, and physician assistants can inject within their scope. In most states a registered nurse can also inject neurotoxins and fillers, but only under delegation and supervision by a physician, NP, or PA, and only after a good-faith exam has cleared the patient. The level of supervision required, and who is allowed to delegate, is where states diverge most.

Estheticians and cosmetologists cannot inject anywhere. Their license covers skincare and surface treatments, not anything that breaks the skin with a needle. Assuming an esthetician can inject, or that an RN can inject without supervision, is how otherwise-careful spas end up out of compliance. The same scope-of-practice logic runs through IV drips, which have their own state-by-state rules in the IV therapy laws by state lookup.

How this is tracked, and sources

Each state's entry reflects the consensus of 2025 and 2026 industry and healthcare-law guides, cross-checked across sources, with the genuinely unsettled states flagged rather than smoothed over. Medical-spa rules sit at the intersection of the medical board, the nursing board, and corporate law, so where those sources pull in different directions, the entry says so. The table was last reviewed in June 2026.

This is general information, not legal advice. These rules change, and the right answer can depend on your exact services, your staff's licenses, and your corporate structure. Confirm the current rules with your state medical and nursing boards and a healthcare attorney before you open or restructure.

Common questions

Can a non-physician own a med spa?

In most states, not directly. The majority apply the Corporate Practice of Medicine doctrine, which means a licensed physician must own the medical practice; a non-physician partners through a management-services (MSO) arrangement that handles the non-clinical side. A minority of states, with Arizona and Florida the most cited, are more permissive about ownership. The lookup shows which applies in your state.

Do you need a medical director for a med spa?

In practice, almost always. In a Corporate Practice of Medicine state the physician owner or a designated medical director is the person legally standing behind every treatment. Even where it is not a separate written requirement, the good-faith-exam and delegation rules mean a physician has to be involved in the care. A med spa running with no physician behind it is out of compliance even where the written rules are light.

Can a registered nurse inject Botox?

In most states an RN can inject neurotoxins and fillers under delegation and supervision by a physician, NP, or PA, after a good-faith exam has cleared the patient. The supervision level and who may delegate vary by state, and a few states, including California and Florida, require closer supervision. Estheticians and cosmetologists cannot inject anywhere.

Is a good-faith exam required before treatment?

Nearly everywhere. A physician, NP, or PA has to examine the patient and confirm the treatment is appropriate before it is performed; an RN can assist but cannot generate the order. Many states allow that exam by telehealth, which is what lets a remote provider clear patients; a few still expect an initial in-person visit. It cannot be skipped.
