Massachusetts' Department of Public Health treats botulinum toxin, soft tissue fillers, chemical peels, sclerotherapy and laser, light and radiofrequency device treatments as medical services, to be performed by, or under the direction or supervision of, a medical practitioner. That comes from the department's medical spa advisory dated December 20, 2013, as posted by the state. The Board of Registration in Medicine's rules add that a physician may not delegate a medical service to anyone who is not licensed to perform it in Massachusetts. Botox Cosmetic is a prescription medicine, according to its FDA label.
Registered nurses and licensed practical nurses may inject. The Board of Registration in Nursing's Advisory Ruling 13-01, revised January 10, 2024, places botulinum toxins and absorbable fillers, including hyaluronic acid, within RN and LPN scope. The nurse acts on the orders of an authorized prescriber, and the patient assessment must be done and documented by an RN or that prescriber. A nurse who is not an advanced practice nurse with prescriptive authority may not choose the drug, the dose, the device or its settings, and may not buy or obtain the drug.
The same ruling says nurses may not do cosmetic procedures in an organization without policies that require informed consent and a comprehensive, documented evaluation by an authorized prescriber. The consent must tell you the operator's qualifications, licensure and expected outcomes. For physicians, the Board of Registration in Medicine's prescribing policy says a doctor must take and record an appropriate medical history and exam at the first encounter before prescribing. A 2004 state consumer advisory on Botox, as posted by the state, says treatment presupposes a doctor's thorough exam and complete history; it is an older advisory, not a regulation.
Nurse practitioners prescribe under guidelines agreed with a supervising physician, or with a supervising nurse practitioner who has independent practice authority. State law gives a nurse practitioner that authority after at least two years of supervised practice following board-recognized certification. Physician assistants perform medical services under a registered physician's supervision, which the statute says must be continuous but does not require the physician's personal presence. Under the nursing ruling, ablative (vaporizing) laser procedures are limited to board-authorized advanced practice nurses.
Two points are not clearly addressed in the rules we read. We found no statute, regulation or board ruling that says whether the ordering prescriber must be on site when an RN or LPN injects. And where a physician allows a physician assistant to perform major invasive procedures, the medical board requires written protocols that set the level of supervision, but the text does not say whether a cosmetic injection counts as one. Ask who the prescriber is and where that person will be during your appointment.
Lasers are treated as medicine for certain cosmetic uses. A 2009 Radiation Control Program notice, as posted by the state, says using lasers for certain cosmetic procedures is the practice of medicine regulated by the Board of Registration in Medicine. Any facility using a Class 3B or Class 4 laser must register with the Department of Public Health's Radiation Control Program before operating and post its current certificate of registration conspicuously. RNs and LPNs may use non-ablative lasers and light devices for procedures such as hair removal and photorejuvenation once they complete a laser physics and safety course.
Here the agencies conflict. The Department of Public Health's 2013 advisory lists laser, light and radiofrequency devices as medical services. The Board of Registration of Cosmetology and Barbering lets licensees with at least 30 hours of training on the device use IPL: its scope policy, last amended December 23, 2025, allows cosmetologists, aestheticians and electrologists to use it for hair removal and aestheticians also for photofacials. The board bars cosmetologists and aestheticians from laser hair removal, which only electrologists it has approved after a board-approved laser course may perform. Which rule controls in a given med spa is unclear, so if an aesthetician will use a light device on you, ask who authorized it and who supervises.
Aestheticians cannot inject. Massachusetts law limits aesthetics to methods that are minimally invasive and pose minimal risk, and the cosmetology board's policy on practices outside the scope of licensure, last amended December 23, 2025, bars its licensees from any injection, including Botox and dermal fillers. The same policy bars chemical peels or services that affect skin beyond the epidermis, body contouring, radiofrequency procedures and plasma skin tightening, and it says there is no such license as a "medical aesthetician".
Microneedling is the second conflict. The cosmetology policy lets its licensees do microneedling, nano-needling or microchanneling that penetrates only the epidermis, and bars anything that reaches the dermis. The nursing board's ruling treats microneedling as acupuncture, which the Board of Registration in Medicine regulates, and places it outside nursing practice. Whether a physician may delegate a medical cosmetic procedure to an aesthetician is also not clearly settled: the cosmetology policy contemplates that kind of delegation while saying the board does not authorize it, and the medical board bars delegating medical services to anyone not licensed to perform them. Before microneedling, ask who will do it, what license that person holds and how deep the needles go.
Then there is the business itself. The Department of Public Health's advisory says a med spa that provides medical services needs a clinic license unless it is wholly owned and controlled by one or more of the practitioners who provide those services, and the state's clinic definition draws the same line. A practitioner-owned med spa is overseen by the practitioner's licensing board instead.
