Physicians, nurse practitioners, and physician assistants can legally perform microneedling in every state. Past that core group, who can perform microneedling depends on your state, the practitioner’s license, and how deep the needles go. Microneedling that penetrates living skin is generally treated as a medical procedure, so non-medical practitioners either face tight restrictions or are shut out entirely.
Who Can Perform Microneedling in Every State
Doctors hold the widest authority. Dermatologists, plastic surgeons, and other physicians can perform microneedling at any needle depth, including the deeper settings used for acne scarring, stretch marks, and skin rejuvenation. Their training covers skin anatomy, wound healing, sterile technique, and complication management, which is what deeper microneedling demands.
Nurse practitioners and physician assistants also perform microneedling at all depths. In states that grant NPs full practice authority, they can offer it independently. In more restrictive states, a collaborative agreement or supervisory relationship with a physician is required. PAs generally need a supervising physician, with the level of supervision set by state law.
Registered nurses can typically perform microneedling when a physician, NP, or PA delegates the procedure and provides general supervision. Licensed practical nurses and medical assistants face tighter rules and usually need direct, on-site supervision from a physician, NP, or PA. In every arrangement, the diagnosis and treatment-planning steps stay with the physician or independent practitioner and cannot be handed down to RNs, LPNs, or medical assistants.
Estheticians and Cosmetologists: It Depends on Your State
This is where the rules fracture. Some states flatly prohibit estheticians from performing any microneedling, treating the entire procedure as invasive and outside the esthetician scope of practice. Other states let estheticians perform superficial microneedling but draw the line at deeper treatments that reach the dermis. A smaller number allow estheticians to perform microneedling only inside a medical practice under physician supervision.
The dividing line is almost always needle depth. Devices that only create micro-channels in the outermost skin layer are often treated as cosmetic-level treatments. Devices that reach into the dermis trigger a full wound-healing response and are almost universally classified as medical-grade procedures. That depth distinction drives most state regulatory decisions about who can hold the device.
The FDA does not draw a bright line at a specific millimeter measurement. Instead, the agency distinguishes between microneedling products that only disrupt the stratum corneum (the outermost layer of dead skin cells) and products that penetrate into living skin layers. Products that only exfoliate or improve skin appearance without reaching living tissue are generally not regulated as medical devices. Products with longer or sharper needles that penetrate living skin and are intended to change the structure or function of tissue are regulated as medical devices.1U.S. Food and Drug Administration. Microneedling Devices The industry commonly references 0.3 millimeters as the approximate depth separating cosmetic treatment from medical-device territory, but that figure is an industry convention, not a number the FDA has published.
If you are an esthetician thinking about offering microneedling, check with your state cosmetology or esthetics licensing board before touching a device. If you are a consumer, ask what license the person holding the pen actually holds. A wrong answer to that question is your clearest red flag.
Radiofrequency Microneedling Is Narrower
Radiofrequency (RF) microneedling combines traditional microneedling with radiofrequency energy delivered through the needles. The FDA classifies RF microneedling as a medical procedure, not a cosmetic treatment, and warns that the devices should not be used at home.2U.S. Food and Drug Administration. Potential Risks with Certain Uses of Radiofrequency RF Microneedling – FDA Safety Communication
In October 2025, the FDA issued a safety communication flagging serious complications from RF microneedling, including burns and scarring, fat loss beneath the treated area, disfigurement, nerve damage, and the need for surgical repair or other medical intervention to treat injuries. The agency recommends that consumers seek RF microneedling only from a licensed health care provider with specific training and experience with RF devices, and that they ask which device will be used.2U.S. Food and Drug Administration. Potential Risks with Certain Uses of Radiofrequency RF Microneedling – FDA Safety Communication
Given these risks, RF microneedling generally falls within the physician, NP, and PA scope of practice. Estheticians and cosmetologists should assume they are not authorized to perform RF microneedling unless their state has carved out an explicit exception.
What the FDA Has Not Authorized Anyone to Do
Even a properly licensed practitioner is not authorized to use a microneedling device for every service you might see advertised. Microneedling devices are not authorized for delivering cosmetics, topical medications, vitamin solutions, drugs, or blood products like platelet-rich plasma (PRP) into the skin.1U.S. Food and Drug Administration. Microneedling Devices This matters because many med spas and clinics market “PRP microneedling” or “vampire facials” as a premium service. The FDA’s position is that the combined risks have not been evaluated and the devices were never reviewed for that use.
The FDA also warns that needle cartridges must be new for each patient and each treatment session. Reusing cartridges, even after cleaning, is unsafe and inconsistent with the terms of the device’s FDA authorization.3U.S. Food and Drug Administration.

Medical Spas and the Supervising Physician Question
Medical spas sit at the intersection of medicine and aesthetics, and that hybrid status drives who can legally perform microneedling in the room. In most states, a medical spa offering microneedling must operate under the supervision of a licensed physician. The specifics vary. Some states require the physician to be physically on-site whenever medical procedures are performed. Others allow the physician to be available by phone or video as long as protocols and treatment plans are already in place.
The supervising physician is generally responsible for every patient treated at the facility, even if they never personally hold the microneedling pen. The physician must ensure proper patient assessment, create or approve treatment plans, establish safety protocols, and remain available to manage complications. When non-physician providers at a medical spa perform microneedling, it is almost always through a delegation arrangement where the physician retains legal responsibility for the outcome.
Before you book, ask two questions. Who is the supervising physician, and what is their actual involvement with the practice? A medical spa where the “medical director” is a physician in name only, with no real oversight of day-to-day treatments, is a compliance problem that translates into a safety problem for you.
How to Verify a Practitioner Before Your Appointment
Checking credentials is straightforward and worth ten minutes. Every state keeps online databases where you can look up a practitioner’s license status, confirm it is current, and review any disciplinary history. For physicians, PAs, and nurses, search your state medical board website. For estheticians and cosmetologists, check your state cosmetology or barbering board. These databases typically show license type, issue and expiration dates, and any formal actions taken against the practitioner.
Past the license lookup, ask the practitioner directly about their microneedling training. The FDA recommends choosing a health care provider specifically trained in microneedling, not just generally licensed to practice medicine or esthetics.3U.S. Food and Drug Administration. Microneedling Devices: Getting to the Point on Benefits, Risks and Safety Useful questions include:
- What specific microneedling training or certification have you completed?
- What device do you use, and is it FDA-cleared?
- How many microneedling procedures have you performed?
- Who is the supervising physician, if the practitioner is not one?
- Is a new needle cartridge used for every patient and every session?
A qualified practitioner answers these without hesitation. Evasion or annoyance at being asked is itself a disqualifying answer. The FDA also recommends confirming that any device used is one the agency has actually authorized, since unreviewed devices carry unknown risks.1U.S. Food and Drug Administration.

What Happens When Someone Performs Microneedling Without Authority
Because medical-grade microneedling penetrates living tissue, performing it without proper licensure or outside an authorized scope of practice often amounts to the unauthorized practice of medicine. Depending on the state, that can bring license revocation or suspension, fines and formal board censure, criminal charges ranging from misdemeanors to felonies, and civil liability if a patient is injured. State licensing boards publish disciplinary actions publicly, so a scope-of-practice violation follows a practitioner’s career. For consumers, those public records are a useful screening tool. Any practitioner with a prior disciplinary action for unauthorized practice is one to avoid.
