Med spa vs. dermatologist: how to choose the right provider for your concern

The line between a med spa and a dermatologist's office has blurred significantly over the last decade — both settings offer Botox, fillers, lasers, and chemical peels. But the underlying purpose of each setting is different, and understanding that distinction helps you match your concern to the right provider.

What dermatologists do

Dermatologists are physicians (MD or DO) with 4 years of medical school and a 3-year dermatology residency. Their training covers:

Medical dermatology — diagnosing and treating skin diseases: eczema, psoriasis, rosacea, contact dermatitis, infections, autoimmune conditions
Surgical dermatology — skin cancer excision, Mohs surgery, biopsies
Cosmetic dermatology — the overlap with med spas: Botox, fillers, lasers, chemical peels

Board-certified dermatologists are uniquely positioned to evaluate whether a skin concern is cosmetic or medical — a distinction that matters more than most patients realize.

What medical spas do

Med spas focus on cosmetic and aesthetic treatments: injectables, laser treatments, body contouring, skin rejuvenation. They're supervised by a licensed medical director (MD, DO, NP, or PA depending on state), and treatments are typically performed by licensed injectors, nurses, or aestheticians under appropriate scope.

The advantage of a med spa over a cosmetic dermatologist for purely aesthetic concerns is often:
More dedicated focus on aesthetic technique and experience
More time per appointment for consultation and treatment
Often competitive pricing relative to high-end dermatology practices

When to see a dermatologist

Go to a dermatologist when:

You have a concerning lesion — mole that changed, growth that bleeds, anything that may be skin cancer
Your skin condition (eczema, rosacea, psoriasis) is unmanaged or worsening
You've had prior skin cancer or have significant risk factors
You're seeking a prescription topical (tretinoin, clindamycin, hydroquinone) and want a physician-level evaluation of your full skin picture
You have a complex or undiagnosed skin condition you want properly evaluated before any aesthetic treatment
You need a biopsy or surgical procedure

The rule of thumb: if you're not sure whether your concern is medical or cosmetic, start with a dermatologist.

When to see a med spa

Go to a med spa when:

You want Botox, fillers, or neuromodulators for cosmetic concerns — experienced injectors at a well-run med spa do this all day, every day, and may have more concentrated aesthetic technique than a dermatologist whose practice balances cosmetic and medical work
You're looking for laser hair removal, IPL, or fractional resurfacing for cosmetic goals
You want body contouring, microneedling, PRP, or chemical peels from a provider whose practice centers on these treatments
You have a wellness goal (IV therapy, hormone optimization, peptide protocols)
You want a consultation with a licensed esthetician for skincare regimen building

The overlap: cosmetic treatments at both settings

Botox and fillers are offered at both settings. The decision isn't "dermatologist = better" or "med spa = better" — it's about the individual provider's experience and training in that specific treatment.

A dermatologist who does 10 filler cases per month alongside 200 skin checks has different injection experience than a dedicated injector at a med spa who does 30 filler cases per week. The reverse is also true — some dermatologists are extraordinarily skilled aesthetic injectors.

Evaluate both settings by:
Reviewing before/after portfolios specific to your treatment
Asking about provider credential and years of experience in that specific treatment
Reading reviews that specifically discuss the treatment you're considering

When you need both

Some patients benefit from a coordinated approach:

Melasma: A dermatologist diagnoses and manages the underlying condition; a skincare-focused med spa provider administers appropriate treatments (careful peels, prescription topicals) under that guidance
Post-acne scarring: Dermatologist confirms scarring type and manages active acne; med spa provides microneedling, laser, or PRP protocols
Aging skin with both cosmetic and medical concerns: Annual dermatologist check for skin cancer screening + med spa for aesthetic rejuvenation

You don't have to choose one provider permanently. The best outcomes often involve a dermatologist and an aesthetic provider working in complement.
