We tested 10 real med spas in LA against ChatGPT and Perplexity — zero got named

August 18, 2026 · 5 min read

We asked ChatGPT and Perplexity to name a med spa in LA. Neither one came up with a single business we actually tested.

Here's how we set it up. We grabbed 10 real, independently-owned medical spas in Los Angeles — no chains, no celebrity-doctor brands, just regular local shops doing the work. Then we fed GPT-4o and Perplexity's Sonar the exact query a customer would actually type: "what are the top medical spas in Los Angeles?" We wanted to see if any of our 10 made either list.

Nothing. Zero across the board. GPT-4o didn't name a single one. Perplexity didn't either. We'd run this same experiment that week with day spas, yoga studios, salons, wellness retreats — every other category had at least a few businesses surface. Med spa stood alone: a complete blank.

That's not statistical noise. That's an entire industry category the AI simply doesn't register.

Who actually showed up?

Both models were plenty eager to answer — ten polished, confident recommendations each. They just weren't about anyone we'd tested. GPT-4o opened with Skin Laundry, Le Jolie Medi Spa, Facile Dermatology, The M Day Spa, Lasky Aesthetics — all legitimate operations, none of them ours. Perplexity took a completely different tack: Volure MedSpa, NassifMD (yes, that Dr. Paul Nassif, the one from reality TV), Rejuva Medical Aesthetics, complete with named physicians, specialties, and tidy "why they're top-rated" explanations.

The deeper problem isn't just the zero — it's that GPT-4o and Perplexity couldn't even agree with each other. Same question, same city, same week, two entirely different top-10 lists with barely any overlap. One system favored quick-treatment chains. The other chased celebrity-physician clinics. So if you're running a med spa, you don't have one AI gatekeeper to worry about. You've got several — and they've each drawn their own conclusions, and not one of those conclusions includes you unless you force the issue.

This wasn't an anomaly. It's the worst-performing category we've tested.

That LA experiment was part of a larger sweep — 50 businesses across five wellness verticals, both models, same methodology. Overall, 66% of the businesses we tested never got mentioned by either engine. Med spa hit absolute bottom: 0% cited. Day spas managed 50% getting named by at least one model. Wellness retreats hit 60%. Yoga studios and boutique salons fell somewhere between, both swamped by chains — CorePower, Black Swan — the same way med spa got drowned out by physician-brand names.

Why does med spa fail harder than everything else?

Our read, based on what the models actually surfaced: this is a trust problem, and AI defaults to whatever trust signal requires the least interpretation. A "medical" spa lives in ambiguity — is it a spa, a clinic, a doctor's office? The models resolve that confusion by grabbing something unambiguous: a named physician, a recognizable brand, a specialty they can nail down in one sentence. "Dr. Paul Nassif's facial plastic surgery clinic" — that's something a model can say with conviction. "Bliss Point Medical Spa, a local injectables studio" — not so much, unless the model has clear on-page information about who's licensed and what exactly they do.

That's a pattern, not proven causation, and we're not dressing it up as more than that. But it matches what we keep seeing: the businesses that surface are the ones that made themselves easy to describe in one confident sentence. The ones that vanished generally hadn't.

Where we'd actually start, if this were our shop

We're not claiming one post solves an industry's AI visibility crisis. But here's our actual priority list:

• Get a named, credentialed provider on your homepage — not buried in your "about" section. Medical director, board certification, years in practice. The models we tested leaned heavily on physician names as trust anchors. If yours takes three clicks to find, you're asking the model to work harder than it typically will.
• State your specialties in plain language, once, clearly. Not a sprawling services menu — one sentence a model could literally extract: "we specialize in injectables and laser resurfacing." Ambiguity is what killed the businesses in our test.
• Get onto platforms models actually trust for medical-adjacent categories — RealSelf, Healthgrades, Zocdoc — not just Google Business Profile. General local signals didn't help anyone here; med spa behaves more like healthcare than hospitality.
• Check what's already being said about you before you change a thing. You might already be the rare exception who's cited. You might be starting from the same zero our ten businesses did. Either way, know before you guess.

That last step takes thirty seconds. Plug your business name and city into our free check, and you'll see exactly what ChatGPT and Perplexity say — or don't say — about you right now. No signup, nothing to install. Most med spa owners have never looked. Given what we just found, that's the first problem worth solving.
