Three different types of practice, significant overlap, and almost no clear guidance on which one you actually need. Here's an honest breakdown.
See a dermatologist for medical skin conditions, suspicious lesions, or skin cancer screening. See a plastic surgeon if you need actual surgery. See a medical spa for non-surgical aesthetic treatments — injectables, biostimulators, lasers, and resurfacing. The categories overlap heavily in cosmetic work, and for non-surgical treatments the individual provider's training matters more than which sign is on the door.
A dermatologist can inject filler. A plastic surgeon can do laser resurfacing. A medical spa can treat acne scarring. Many concerns can be addressed at all three, which is why the "which one do I need" question doesn't have a clean answer.
What does have a clean answer: certain problems belong to one category and not the others. Everything else comes down to the individual provider.
A board-certified dermatologist completes residency training in diagnosing and treating diseases of the skin. This is a recognized medical specialty, and their core scope is medical rather than cosmetic — though many also offer aesthetic services.
A board-certified plastic surgeon completes surgical residency training. Their defining capability is operating — procedures requiring incisions, anesthesia, and structural change that no injectable or device can replicate.
A medical spa provides aesthetic treatments under medical licensure without surgery. The category is broad and inconsistently regulated in terms of who performs treatments, which is why provider credentials matter more here than in the other two categories.
A physician with fifteen years of injectable experience will produce better filler results than a newly-trained provider — regardless of whether the practice is labeled a medical spa, a dermatology office, or a plastic surgery clinic. The category on the sign is a weaker signal than who is holding the needle and how much specific experience they have with your particular treatment.
The most common genuinely difficult call is skin laxity. Mild to moderate laxity often responds well to non-surgical treatment — RF microneedling, biostimulators, and resurfacing lasers can meaningfully improve it. Significant laxity, where there's genuine excess skin to remove, does not. No injectable or energy device removes tissue. An honest provider will tell you which situation you're in, even when the answer is "you need a surgeon, not me."
Plump Medical Spa is a physician-owned, doctor-only medical spa in Newport Beach. Dr. Amir Mortazavi, MD personally performs every treatment — no nurse injectors or delegated procedures. The practice does not perform surgery and does not diagnose or treat skin disease; patients with medical dermatologic concerns are referred appropriately.
Where the practice concentrates is the non-surgical end of aesthetic medicine, with particular focus on cases that require combining modalities or correcting prior work: ultrasound-guided filler dissolving, Myobloc for neurotoxin resistance, and multi-modality acne scar correction.
I refer patients out regularly — to dermatology for anything that looks like it needs a biopsy, and to surgery when someone's laxity is genuinely beyond what injectables and energy devices can address. Telling someone a treatment won't get them where they want to go is more useful to them than selling it anyway.
Should I see a medical spa, dermatologist, or plastic surgeon?
It depends on what you're treating. See a dermatologist for medical skin conditions, suspicious lesions, or skin cancer screening. See a plastic surgeon if you need surgery — a facelift, eyelid surgery, or an implant. See a medical spa for non-surgical aesthetic treatments including injectables, biostimulators, lasers, and skin resurfacing. Many patients see more than one over time.
Is a medical spa the same as a dermatology office?
No. Dermatology is a recognized medical specialty focused on diagnosing and treating conditions of the skin, hair, and nails, including skin cancer. A medical spa provides non-surgical aesthetic treatments under medical licensure. Some dermatologists also offer aesthetic services, and some medical spas are physician-owned, so the categories overlap in practice.
Do I need a plastic surgeon for filler or Botox?
No. Injectable treatments are non-surgical and are performed at medical spas, dermatology offices, and plastic surgery practices alike. What matters more than the practice type is who physically performs the injection and their level of anatomical training and experience.
When should I see a dermatologist instead of a medical spa?
See a dermatologist for anything that may be a medical condition rather than a cosmetic concern — changing moles, suspicious lesions, persistent rashes, severe or cystic acne requiring prescription management, autoimmune skin conditions, or annual skin cancer screening.
Can a medical spa treat acne scars, or do I need a dermatologist?
Both can treat acne scarring. What matters is whether the provider can offer the specific modalities your scar type requires — subcision for tethered rolling scars, resurfacing lasers for textural change, biostimulators for volume, and pigment treatment for post-inflammatory marks. A practice limited to one modality will be limited in what it can correct.
Is a physician-owned medical spa different from a regular med spa?
Yes, though the terminology is inconsistent. Some medical spas are owned by non-physicians and employ a medical director for oversight. Others are physician-owned but delegate treatments to nurses. A smaller number are physician-owned and physician-performed, where the doctor personally performs every treatment.
