Federal law does not tell you who may fire a cosmetic laser, and it says so on the label. Under 21 CFR § 801.109, a prescription device has to carry the statement that federal law restricts it “to sale by or on the order of a ___”, and the blank is filled with “physician” or with “the descriptive designation of any other practitioner licensed by the law of the State in which the practitioner practices to use or order the use of the device.” Federal law points at the state. So a vendor telling you the device is Rx-only has answered a different question than the one you asked.
The states answer it, and they do not agree. More usefully for an operator, two states can reach the same practical outcome through machinery so different that copying one setup into the other leaves you unsupervised.
The federal frame, briefly
21 CFR § 878.4810 classifies the laser surgical instrument for general and plastic surgery and dermatology. A carbon dioxide laser is identified as a device “intended to cut, destroy, or remove tissue by light energy,” and an argon laser as one intended “to destroy or coagulate tissue.” That classification governs the device. It does not govern the operator, and nothing in the federal scheme does.
Four state postures
| Posture | What it means | Examples |
|---|---|---|
| Laser use is the practice of medicine or surgery | The act itself is reserved; delegation is the only route, where permitted | Maryland, South Dakota, Alabama |
| Physician or physician assistant only | No delegation route to nurses or estheticians | New Hampshire |
| Delegable to named categories on stated conditions | Counts, training hours, supervision distance | Ohio, Iowa |
| A separate non-medical certification exists | A cosmetology regulator, not a medical board, licenses the operator | Arizona |
The finding that contradicts the usual advice
You will read that estheticians may never operate lasers. That is not accurate, and the states where they may do so get there by routes that have nothing in common.
Arizona runs it through the health department, not the medical board. A.R.S. § 32-516 is titled “Aestheticians; cosmetologists; cosmetic laser and IPL device use; certification.” An aesthetician or cosmetologist who wishes to perform cosmetic laser and IPL procedures “must apply for and receive a certificate from the department” and comply with the section and department rules. Once certified as a laser technician, they “may use a laser or IPL device.” The statute also grandfathers operators who used these devices before November 24, 2009, if they obtained a certificate before October 1, 2010. This is a credential the operator holds in their own right. No physician stands behind it.
Alabama reaches a similar street-level outcome and calls it medicine. Ala. Admin. Code r. 540-X-11 states that the use of “lasers/pulsed light devices, or any energy source, chemical, or other modality that affects living tissue (when referring to the skin, anything below the stratum corneum), whether applied for surgical, therapeutic, or cosmetic purposes, is the practice of medicine.” A delegate may operate the device, and the rule then builds the whole apparatus around that: delegation and supervision, written protocols, initial training requirements for physicians and delegates, procedure and device requirements, remote practice sites, alternate physicians, quality assurance and equipment safety. Its definition of direct physician supervision is strict, meaning the physician “is in the physical presence of the patient being treated and is directly observing the use of the modality by a delegate.”
Read those two together. In Arizona the operator carries their own certificate. In Alabama the operator carries nothing, and a physician carries the act. An operator who opens in Alabama using an Arizona staffing model has an unsupervised layperson performing the practice of medicine.
New York rebuilt its rule in 2025, and the new version is the most useful in the country. On March 7, 2025, the New York State Board for Medicine concluded that the use of any energy device, including lasers, “which affect the basement membrane or deeper tissues (e.g., dermis, fat) to treat any ‘physical condition’ constitutes the practice of medicine.” The test is now depth, not diagnosis. Laser hair removal is “specifically excluded from this determination,” and the Education Department, relying on People v. Lehrman, 251 A.D. 451, 296 N.Y.S. 580 (1st Dep’t 1937), “has not acted on the Board’s determination regarding laser hair removal.” For everything else, the Department adopted the Board’s determination.
The Board then published a classification table, which is the thing to copy into your own staffing plan:
| Class | Examples | Depth affected | Practice of medicine | Who may perform |
|---|---|---|---|---|
| I | Handheld LED lights, manual scalpels | Stratum corneum, surface only | No | Trained non-licensed professionals, “e.g., aestheticians” |
| II | IPL devices, non-ablative lasers for hair removal | Epidermis | No | Trained non-licensed personnel under supervision |
| IIIa | Low-level laser therapy for hair regrowth | Epidermis | No | Trained non-licensed personnel under supervision |
| IIIb | Non-ablative skin lasers, therapeutic lasers for pain | Upper dermis | Yes | Licensed medical professionals or supervised personnel |
| IV | CO2 resurfacing lasers, deep RF, laser lipolysis | Dermis and deeper | Yes | Exclusively licensed medical professionals |
So New York does permit trained non-licensed operators, and it tells you exactly where the line falls: at the upper dermis. It also defines the supervision. General supervision means the supervising physician or nurse practitioner “need not be physically present but must be available to provide guidance or intervene within a reasonable period.” And only registered professional nurses, under that general supervision, may carry out orders for energy-device treatment.
That table decides menus. A New York operator running IPL hair removal with trained staff is inside Class II. The same operator adding CO2 resurfacing has moved to Class IV, where the work is exclusively for licensed medical professionals, and no amount of training fixes the staffing.
Three citations to correct in your own documents
These changed recently enough that current agreements and protocols are likely to carry the old numbers.
- Iowa. The laser provision moved from 653-13.8 to 481-655.6. This one matters more than a renumbering usually does: the old citation now points at abortion-drug prescribing standards, so an agreement citing 653-13.8 is not merely stale, it cites something actively wrong.
- Ohio. The nurse supervision cap is five, not two, under ORC § 4731.33(G)(3) as rewritten by HB 377, effective 2026-08-26. The amendment also added an off-site pathway with a forty-hour requirement and a new laser-hair-removal-professional category. Understating the cap leads operators to over-hire physicians.
- Colorado. Rule 800 at 3 CCR 713-30 was recodified as 3 CCR 713-1 Rule 1.17, effective 2023-07-15, and the statutory cross-reference moved from C.R.S. § 12-36-106 to § 12-240-107.
The duty that survives whoever fired the device
Virginia requires the physician to evaluate the patient after a laser complication. That obligation attaches to the physician regardless of who operated the device, which is the point operators miss when they staff to the cheapest lawful operator and stop there. See Virginia’s complication rule.
Before you let anyone operate
- Identify which of the four postures your state takes. Do not reason from a neighboring state.
- Confirm the operator’s own credential, and confirm which regulator issued it. A cosmetology certificate and a medical delegation are not interchangeable.
- Match the supervision standard to the text. “Supervision” in Alabama means physically present and watching. Elsewhere it may mean reachable by phone.
- Keep the training records the rule asks for, by name, with dates.
- Name the physician who responds to a complication, and state how fast.
What this means for you
Staff each location to its own state rule and write the citation into the protocol so the next person can check it. Where the operator holds their own certificate, keep a copy and track its expiry. Where the operator works under delegation, the physician’s supervision obligation is the service you are buying, so price and schedule it rather than treating it as a signature. If you run more than one state, expect the staffing model to differ between them, and resist the pull to standardize the menu across a border. The three citations above should be corrected in your documents this quarter.

Frequently asked questions
Can an esthetician use a laser?
In some states, on conditions. Arizona certifies aestheticians and cosmetologists as laser technicians through its health department under A.R.S. § 32-516. Other states treat laser use as the practice of medicine and allow it only by delegation, and some allow no delegation at all. The answer turns entirely on your state.
Is laser hair removal the practice of medicine?
It depends on the state, and New York shows why. In its March 7, 2025 determination the Board for Medicine specifically excluded laser hair removal, and the Education Department, relying on People v. Lehrman, has not acted on the Board’s determination regarding it. Devices reaching the upper dermis or deeper are the practice of medicine there.
Does the FDA decide who can operate a laser?
No. 21 CFR § 801.109 requires prescription-device labeling naming a physician or any other practitioner “licensed by the law of the State in which the practitioner practices” to use or order the device. Federal law defers the operator question to state law.
What does direct supervision mean for laser treatments?
It varies and the text controls. Alabama defines direct physician supervision as the physician being in the physical presence of the patient and directly observing the delegate’s use of the device. Other states permit a supervising physician who is reachable rather than present.
Who is responsible if a laser treatment goes wrong?
The supervising physician retains professional and legal responsibility in delegation states, and Virginia requires the physician to evaluate the patient after a laser complication regardless of who operated the device.
