How to open a med spa in California

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.

2. The medical oversight you will need

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.

3. What has to happen before a patient is treated

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.

4. Who may actually inject

Whether an RN, NP, or PA may treat, and under whose supervision.

5. What it costs — the part that is a legal question

We do not publish build-out cost estimates. Fit-out, equipment, lease and staffing are real costs and they are not regulatory monitoring — any figure we gave you would be someone else’s estimate with our name on it. What we can tell you, cited, is which of California’s requirements are also spending decisions, because those are the ones that are not optional and the ones with dates attached.

• The physician relationship

  Whatever the state requires here is a recurring cost, not a one-off — a medical director or delegating physician is a paid relationship for as long as you operate.

  A physician may delegate injectable and laser procedures only to appropriately licensed personnel — registered nurses, nurse practitioners, or physician assistants — under genuine supervision. Unlicensed staff (including medical assistants) and improperly licensed staff (estheticians, cosmetologists, LVNs) may not perform them, regardless of training. A “paper” medical-director arrangement is aiding and abetting the unlicensed practice of medicine.

• Registering the facility

  Where a state requires the premises itself to be registered or licensed, that is a filing with a timetable — and a date you can miss.

  ⚠️ California puts a separate license on the sterile compounder. “a pharmacy that compounds sterile drug products shall possess a sterile compounding pharmacy license as provided in this article.” Compounded semaglutide is a sterile drug product, so this is the license a California practice’s supplier must hold — distinct from its ordinary pharmacy license.

• The corporate structure

  The entity the state permits you to trade through determines what you pay to form and maintain it, and sometimes who has to be on the paperwork.

  ⚠️ California’s ban is broad and expressly survives co-ownership. The offer, delivery, receipt or acceptance by a licensee of “any rebate, refund, commission, preference, patronage dividend, discount, or other consideration, whether in the form of money or otherwise, as compensation or inducement for referring patients, clients, or customers” is unlawful — “irrespective of any membership, proprietary interest, or coownership in or with any person to whom these patients … are referred”. Shared ownership is not a defense.

6. 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.

7. What changed in California

• CA SB1089: Preventive Treatment Health Care Act.
