Med spa vs dermatologist vs plastic surgeon: who should you see?

Start with what each name covers, because the three overlap on treatments but not on training or on what they are set up to handle.

A med spa is a practice built around non-surgical cosmetic treatments.

No federal law defines the term "med spa"; the American Med Spa Association (AmSpa), the specialty's trade association, says med spas "are medical practices," and whether one is regulated as a medical practice, and who may own it, is decided by each state's rules.

Our guide to what a med spa is covers the model in detail.

A dermatologist is a physician whose board certification, from the American Board of Dermatology, stands on four years of postgraduate training after medical school.

A dermatology practice is where the American Academy of Dermatology (AAD) sends the diagnosis-type concerns we list below, alongside any cosmetic work it offers.

A plastic surgeon is a physician trained in surgery, with the multi-year requirements described in the next section.

ASPS's own cost statistics cover botulinum toxin, fillers and laser treatments, so plastic surgeons also offer non-surgical work; the defining difference is the surgical training.

A facial plastic surgeon is the fourth name you will see; AmSpa's 2024 report counts facial plastic surgery among the aesthetic "core" specialties, alongside plastic surgery, oculoplastic surgery and dermatology.

We could not confirm in our research how its certification path differs from plastic surgery certification, so ask any surgeon you consult which board certifies them.

A "board-certified" claim should name the board — for example the American Board of Plastic Surgery.

The training numbers are the clearest difference between the three.

A dermatologist certified by the American Board of Dermatology has completed four years of postgraduate training after medical school: a 12-month PGY-1 year plus three years of ACGME-accredited dermatology residency.

A plastic surgeon certified by the American Board of Plastic Surgery has completed at least 6 years in an integrated program, or 3 years of plastic surgery after general surgery training (5 years of residency or an approved alternate pathway).

You can check a doctor's ABMS board certification free at CertificationMatters.org — ABMS boards certify doctors in 38 specialties — and a "board-certified" claim should name the board, like the American Board of Dermatology.

At a med spa, who treats you depends on the treatment and the state.

AmSpa says injecting botulinum toxin is the practice of medicine because a prescription drug is used on living tissue, so it must be done by a physician, an independent-practice NP or another licensed professional acting within their scope, under rules that vary by state.

Before a first treatment, AmSpa explains, a physician, physician assistant or advanced practice nurse takes a medical history, does an appropriate exam and creates the treatment order; an RN may assist but cannot generate the order.

Above them sits a medical director, responsible for all the medical decisions in the practice — AmSpa's phrase is that the work is often delegated, but "the buck stops with the medical director." One of AmSpa's 2024 survey numbers is worth knowing before you book: 74% of medical directors come from outside the core specialties.

That figure does not describe the injector in front of you, which is why the individual's license and training matter more than the sign on the door — our guide to injector credentials explained covers the RN, NP, PA and MD roles.

Think in classes of treatment rather than a blanket rule about provider types.

Injectables are medical treatment wherever they are delivered: AmSpa's position is that injecting a prescription drug like botulinum toxin is the practice of medicine.

For filler specifically, the FDA advises choosing a licensed provider experienced in dermatology or plastic surgery and trained to inject fillers, who uses properly labeled, sealed vials or pre-filled syringes of FDA-approved filler.

The FDA also says not to buy fillers sold directly to the public, not to self-inject, and that needle-free filler "pens" are not FDA-approved.

Skin problems that need a diagnosis are a different class.

The AAD lists concerns that should be seen by a dermatologist first, rather than treated cosmetically: any changing, new, bleeding or itching spot (a possible skin cancer); spots you plan to fade as "age spots"; hair loss, to identify the type; ocular rosacea; and suspected melasma that may be another condition.

On age spots the AAD is direct: if you use a fading treatment on a skin cancer, it can give the cancer time to grow.

Even a redness complaint can need a workup — the AAD notes rosacea has no medical test, and a dermatologist may test to rule out look-alikes such as lupus.

Surgery is the third class.

The AAD contrasts a surgical lift — it names facelifts and eyelid surgery — with non-invasive tightening (ultrasound, radiofrequency, some lasers): the surgery gives what it calls the most dramatic results, while the non-invasive options give modest tightening and lifting.

If the job is surgical, the multi-year surgical training in the last section is what you are choosing, and the conversation starts in a surgical practice.

We could not confirm any neutral national price list for the same treatment across all three provider types, and the figures that do exist measure different things, so they cannot be ranked against each other.

The professional-society figures are average surgeon fees.

ASPS's cost pages (its "latest statistics," read October 2026) list an average botulinum toxin fee of $435, an average of $715 for hyaluronic acid fillers and $697 for laser skin treatments like laser hair removal; these are surgeon fees, not med spa prices, and ASPS's filler and laser figures exclude related expenses.

Med spa numbers are published differently.

AmSpa's 2024 survey of med spa professionals found patients spend an average of $527 per visit — a survey average, not a price list.

Chains publish their own prices per unit or per session: LaserAway's pricing page (read October 2026) listed Botox at $15 per unit, and LaserAway says prices may vary by location, so treat every chain price as that chain's price where it publishes it.

The pricing model matters more than the badge.

Injectables are priced per unit or per syringe, lasers and skin treatments per session or package, and a surgeon's fee is a per-procedure fee.

The practical move is to ask each practice you are considering for a total for your treatment at its own prices, so you compare like with like.

The corporate-practice restrictions AmSpa describes are aimed at non-physician ownership, not at dermatologists or plastic surgeons, but who may own a med spa is still set by each state's rules.

AmSpa explains the corporate practice of medicine (CPOM) doctrine: many states bar non-physicians from owning medical practices directly or through a business entity, out of concern that lay control could interfere with physician judgment.

AmSpa describes states ranging from permissive (it cites Alabama's, Idaho's and North Carolina's med spa rules) to strict (California), with management services organization (MSO) arrangements commonly used where lay ownership is restricted.

No federal law defines a med spa, so those state rules decide — our guide to med spa laws by state carries the specifics.

Ownership also does not tell you who treats you: in AmSpa's 2024 survey, 67% of single-owner med spa practices were owned by non-physicians (NPs, RNs, PAs, entrepreneurs, aestheticians), and 74% of medical directors came from outside the core specialties.

So ask both questions: who owns the practice, and who will actually treat you.

Match the provider type to the job, then vet the specific practice and the specific person.

The list below folds this page into questions you can ask on the phone or at a consultation.

If the answers come back vague — who treats you, what the product is, what happens if something goes wrong — treat that as the finding, not a detail.

Our guide to how to choose a med spa goes deeper on vetting and red flags.

When you have a shortlist of practices near you, verify rather than assume.

Look the physician up at CertificationMatters.org, and the nurse or nurse practitioner up in Nursys, before you book.

Then take the checklist above to the consultation, and read our guides to what a med spa is and injector credentials explained so you know the roles before anyone hands you a mirror.
