How to open a med spa in California
The four things California law decides before you can open: who may own the business, which physician relationship is required, what must happen before a patient is treated, and who may inject. Each area below is cited to California statute or board rule. Verified Jul 26, 2026.
Regulatory monitoring and reference — not legal advice. Verify against the primary source and consult counsel before acting.
1. Can you own a med spa?
Who is allowed to own the business, and in what corporate form?
California strongly bars the corporate practice of medicine. This is the opposite of a permissive-ownership state.

Which physician relationship the state requires, and what they must do.
In California, using prescriptive drugs (Botox, fillers) and prescriptive/energy devices (lasers, IPL) for cosmetic reasons IS the practice of medicine.

The exam or provider-patient relationship required before the first injection.
California requires an appropriate good-faith exam before prescriptive drugs or devices are used — and it may not be delegated to an RN.

Whether an RN, NP, or PA may treat, and under whose supervision.
A registered nurse may inject Botox/fillers or operate a laser only after a physician, NP, or PA has performed the good-faith exam and issued a patient-specific order, and only within standardized procedures in an organized health care system — not as an independent salon practice.

5. What you can put in the syringe
GLP-1 and peptide legality is federal and moves independently of Californialaw — a compounded product can lose its basis nationwide with no change to your state’s rules. Check current standing before you build a service line around one.
