Your esthetician license authorizes non invasive care of the epidermis. That single sentence is the spine of almost every state practice act in the country, and nearly every gray zone you will ever face comes down to one question: does this procedure stay above the basal layer, or does it break the skin and reach living tissue below it?
The line is drawn by depth and by intent, not by the brand name on the machine. A state board does not care whether the device is marketed as a facial device. It cares whether you have removed the barrier, drawn blood, or delivered energy that damages tissue you are not licensed to touch. Once you internalize that, unfamiliar procedures become much easier to classify on your own.
What follows is a working map of where the boundaries usually sit, and, more importantly, how to get a written answer for your own state instead of relying on what a trainer told you at a certification weekend.
Why scope is defined by depth of the skin, not by device name
Boards write rules in anatomical language because product names change every eighteen months. The recurring phrases are worth memorizing, because they show up in almost identical form across many states: superficial, non invasive, the stratum corneum, the epidermis, and the prohibition on procedures that remove living tissue or penetrate below the epidermis.
Practically, that means the same tool can be legal or illegal depending on how deep you take it. A crystal free resurfacing device set to abrade dead surface cells is a different act from the same head set to draw pinpoint bleeding. A pen device with a needle depth of 0.25 mm is a different act from the identical pen set to 1.5 mm.
There is a second layer on top of depth, which is intent. Boards separate beautification of the skin from the diagnosis or treatment of disease. You may treat the appearance of acne. You may not diagnose acne, prescribe for it, or represent yourself as treating a medical condition. That distinction is why the wording on your website is a compliance matter, not only a marketing one.

Chemical exfoliation: pH, peel depth and the usual state limits
Chemical peels are where scope is written most explicitly, and the limits are usually expressed as some combination of acid type, concentration and pH. Many states cap what an esthetician may apply without medical oversight, commonly around a maximum acid concentration in the low tens of percent and a minimum pH, with the specific figures varying by state. Some states name permitted acids directly. Others simply say superficial only and leave the interpretation to the board.
Whatever your state's numbers are, the classification framework is standard:
| Peel depth | Reaches | Typically performed by |
|---|---|---|
| Very superficial | Stratum corneum | Esthetician |
| Superficial | Full epidermis to the basal layer | Esthetician, often with limits |
| Medium | Papillary and upper reticular dermis | Medical setting |
| Deep | Mid reticular dermis | Physician |
Two traps catch experienced practitioners. The first is the manufacturer's own claim: a product sold at a compliant concentration can still exceed your state's limit once you layer it, or once you use it after a mechanical exfoliation that has already thinned the barrier. The second is trichloroacetic acid, which many states restrict or prohibit entirely at any strength for estheticians. Check that one specifically rather than assuming a low percentage is automatically fine.
Microneedling, dermaplaning and the states that restrict them
Microneedling is the clearest example of depth deciding everything. Devices that stay in the very shallow range are treated by some states as cosmetic, while any depth that produces pinpoint bleeding is, by definition, breaking the skin and reaching the dermis. A number of states classify that as a medical procedure outright, some allow it only under physician delegation and supervision, and some permit estheticians to perform it at limited depths. There is no national answer, and the answer in your state may have changed since you trained.
Dermaplaning splits along a different question: whether scraping the skin with a surgical blade counts as within cosmetology scope at all. Some boards permit it as exfoliation and hair removal. Some are silent, which is not the same as permission. Some require a specific certification or restrict blade use.
Two things to check on both procedures. Does your professional liability policy explicitly cover the procedure and the depth you use, or does it exclude anything that breaks the skin? And is your device cleared by the FDA for the use you are putting it to, since a device cleared only for use by licensed medical professionals does not become legal for you because a distributor sold it to you.
Lasers and IPL: which states require physician supervision
Light and laser devices are regulated on a separate track from the cosmetology practice act, because many states place the use of energy devices under the medical board rather than the board of cosmetology. That is why a state can be permissive about peels and strict about IPL.
The models you will encounter, in rough order of restrictiveness:
- Physician only. Laser and IPL treatment is the practice of medicine, delegable only in limited circumstances or not at all.
- Delegated with on site supervision. You may operate under a physician, physician assistant or nurse practitioner who is physically present, following a written protocol and after a good faith exam of the client.
- Delegated with indirect supervision. The supervisor must be reachable and available, but not in the building.
- Certification based. A separate laser technician credential, registration or training requirement exists alongside your esthetics license.
Note that most states treat the good faith medical exam and the standing written protocol as non negotiable in any delegated model. A signed piece of paper from a physician you have never met, in a state that requires an exam of each client, does not protect you.

Extractions, lancets and what counts as invasive
Manual extraction with fingers, cotton and gentle pressure sits comfortably inside every esthetics scope in the country. The lancet is where opinions diverge. Some states permit a sterile lancet to open a closed comedone. Others explicitly prohibit any use of a needle or sharp that penetrates the skin.
Related items that are almost universally out of scope: removing skin tags or moles by any method, cauterizing or freezing anything, injecting anything at all, and using any prescription only substance. Also out of scope in most states is treating skin that is visibly infected, inflamed beyond a normal comedone, or that shows a lesion you cannot confidently identify. That last one is a referral, and documenting the referral protects you.
Master esthetician licenses and what they add
A handful of states issue a second tier license, variously called master esthetician or advanced esthetician, requiring several hundred additional training hours beyond the basic license. Where it exists, it usually expands access to stronger chemical exfoliation, certain light devices, and sometimes limited microneedling, always within the specific list that state publishes.
Two cautions. The credential is not portable: a master license in one state may not transfer at all, and reciprocity for the basic license does not carry the advanced privileges with it. And a private certificate from a training company, however long the course, is not a license. Only the state issues scope.

Medical spa supervision agreements in plain terms
If you work under a physician, or plan to bring one in, know what the arrangement actually consists of before you sign. In plain terms it is usually four documents and one ongoing obligation.
- Written protocols covering each delegated procedure: indications, contraindications, settings, and what to do in an adverse event.
- A delegation agreement naming the supervising practitioner, the procedures delegated, and the supervision level required by your state.
- A good faith exam process establishing who examines each new client and how that is recorded.
- Chart records kept to a medical standard, retained for the period your state requires.
- Ownership rules. Many states restrict who may own a practice that provides medical services, which can make a management services arrangement necessary rather than optional.
If a company offers you a supervising physician for a flat monthly fee and no exams, treat that as a warning sign rather than a solution.
How to read your own practice act and get a written answer
This is the section to actually use. The sequence takes about an hour.
- Find your state's cosmetology or barbering and cosmetology board site, and locate two separate documents: the statute, which is the practice act passed by the legislature, and the administrative rules, which are the regulations the board adopts. The specifics you need are usually in the rules.
- Search the rules for the definitions section first. Read the definition of esthetics or skin care in full, then read every prohibition.
- Search for the words invasive, dermis, epidermis, needle, laser, light, peel, exfoliation and blade. Those eight terms will surface nearly every relevant provision.
- Check the board's published newsletters, meeting minutes and declaratory rulings. Boards often clarify contested procedures there years before the rules are formally amended.
- If it is still unclear, email the board directly. Describe the exact procedure, the exact device, the exact depth or concentration, and ask whether it falls within the esthetics scope. Ask for a written reply.
- Save the reply as a PDF with the date, and send the same description to your liability carrier for written confirmation of coverage.
Phone calls do not protect you. A dated written answer from the board, in your file, does.
Keeping the record that backs you up
Scope compliance ultimately shows up in your charting. If a complaint is ever filed, the question is what you assessed, what you told the client, what you performed and at what strength, and what you referred out. That record either exists or it does not.
GlowIntake keeps that documentation as a byproduct of the work you already do: a structured skin consultation, condition tracking that carries visit to visit, and a written plan the client receives. When you need to show what you did and why, it is there.
