Your coverage should match your treatment menu. All of it.
A med spa looks simple from the waiting room. Behind it, there's a list of services, a list of providers, a supervising arrangement, expensive equipment and a lot of client data. Each one shapes the insurance. Aesthetic offices and med spas are one of the kinds of businesses Mark focuses on, so we've had this conversation many times.
The heart of the program is professional liability, because general liability doesn't cover the treatments you provide. Around it sit general liability for the space, property for your build-out and inventory, and coverage for lasers and devices, which may be better handled through inland marine or equipment breakdown than a standard property limit. Add cyber liability for client records, payment data and before-and-after photos, and EPLI once you have a team.
One honest note. Some aesthetic procedures are harder to place than others, and coverage typically depends on who performs each procedure and how it's supervised. A policy written around one service list may not respond to a service you added later. So when you call, give us the full menu: every treatment, who performs it, their credentials, and your supervision setup. The more complete the picture, the better we can match the coverage. Nothing on this page is legal or regulatory advice.
