“Med spa” has no single legal definition in the United States. It is a market term, not a licensure category, and what it means in practice is set by your state’s medical board, your corporate practice rules, and what you actually do inside the building.
That vagueness is why the term gets used for two completely different businesses — and why the distinction matters more to an owner than to a patient.
Med Spa vs Day Spa: the Distinction That Actually Matters
Dr. Chris Croley, Empire’s Chief Medical Officer, puts the confusion plainly.
“Where there’s some kind of confusion in this space is many times they’re confused with day spas, where we’re using non-healthcare professionals to do aesthetic services — facials, and maybe massages,” he said. “When we think about a med spa, we’re really thinking about a medical aesthetic practice. It is a medical practice at the core, and we’re providing medical services.”
That sentence carries the whole operational difference. A facial is a service. A neurotoxin injection is the practice of medicine, and it brings with it a medical director, a good faith exam, delegation rules, emergency preparedness, documentation standards and liability that no amount of spa-like branding removes. Empire covers that side directly in Aesthetic Practice Legal & Licensing.
Practices get into trouble when the front of house is designed as a spa and the back of house has not been built as a medical practice.
What a Med Spa Needs: Medical Director, Protocols, Emergency Readiness
Michelle Langston APRN, who owns a practice in San Diego, was asked to define one and answered with infrastructure rather than services.
“A med spa to me is an office that has a well-trained leader, a great medical director — whether it is a nurse practitioner or a physician — that is actively involved in that clinic,” she said. “Somebody that is operating a business that has a great foundation. They have emergency protocols, they have safety protocols, they value education not only for themselves but for everyone on their team, and they have a robust, entire protocol for every single procedure that they do.”
Read that list again as a checklist, because every item on it is something a practice either has or does not:
- A medical director who is actually involved. Not a name on a form. Actively involved in the clinic.
- Emergency protocols — written, and rehearsed by the people who would have to use them.
- Safety protocols distinct from emergency ones: screening, contraindications, when not to treat.
- Education budgeted for the whole team, not only the owner.
- A documented protocol for every procedure on the menu. Every one, not the complicated ones.
A practice that offers ten services and has protocols for three is not a med spa with a gap. It is a med spa for three of its services and something less defensible for the other seven.
Why Patients Cannot Tell a Med Spa From a Day Spa
Langston’s next sentence is the one worth acting on, and it is a marketing problem disguised as a safety one.
“Patients don’t really know how to ask for that. It is hard to say that,” she said. “So I think we have to communicate that in our culture.”

A patient choosing between two clinics cannot assess your emergency protocol. They can assess your parking, your reception area and your Instagram grid. So the practice that has actually built the medical infrastructure gets no credit for it unless it says so.
Her answer is to put it where a patient will find it: “We can do that through social media, or have things on our website to talk about the things that we do and that we offer, and where our foundation is, and a bio about every single injector.”
An injector bio is not vanity. It is the only way most patients can tell a medical aesthetic practice from a day spa with a laser.
How to Open a Med Spa: What to Do First
Two Empire courses map onto the two routes people take: Starting an Aesthetic Practice While Still Working for clinicians keeping a salaried job, and Working for a Med Spa for those who would rather inject than own.
Tatiana Sarmiento, who practices in Florida and teaches for Empire, gets asked how to begin more than any other question — and her advice is to delay the building, not the learning.
“First get your knowledge. Practice between friends and family. Start small before you invest in an office and in devices, in a front desk, in hiring people,” she said.
Her reasoning is about the skill rather than the money: “You need to craft and improve your artistic eye and your hands. This is different than the regular medicine that we’ve been doing in a primary care practice.”
Croley adds the foundation that the sequence rests on: “Getting your basic education foundation, really understanding anatomy. I cannot stress that enough. That is the foundation of everything.”
He also names the asymmetry that catches new injectors: people are frequently unafraid of neurotoxin, because most neurotoxin complications are minor and temporary — an asymmetry, a brow sitting higher than the other, something that wears off. Filler is where the risk changes category, and where the fear should live. New Injector Confidence is built around exactly that asymmetry.
So, What Is a Med Spa?
The practical answer, drawn from how these three describe it:
A med spa is a medical practice that happens to deliver aesthetic outcomes. It is defined by its medical director, its protocols and its emergency readiness — not by its menu, its décor or the word on the signage. A business that offers medical procedures without that infrastructure is not a med spa operating loosely. It is a medical practice operating without the things that make a medical practice safe.
And because patients cannot see any of that from the waiting room, a practice that has built it properly has to be willing to say so out loud.
