California med spa & injectable regulations

Physician supervision & delegation

In California, using prescriptive drugs (Botox, fillers) and prescriptive/energy devices (lasers, IPL) for cosmetic reasons IS the practice of medicine.

• 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.

  Cal. Bus. & Prof. Code §2052; Medical Board of California — Medical Spas guidance

• For an elective cosmetic laser or IPL procedure performed by a licensed provider, a trained physician must be “immediately available” — reachable without delay and able to direct throughout the procedure.

  Cal. Code Regs. tit. 16, §1364.50

Good-faith examination

California requires an appropriate good-faith exam before prescriptive drugs or devices are used — and it may not be delegated to an RN.

• Prescribing, dispensing, or furnishing a dangerous drug (such as Botox or fillers) without an appropriate prior examination and a medical indication is unprofessional conduct.

  Cal. Bus. & Prof. Code §2242(a)

• Per the Medical Board, the required prior examination may NOT be delegated to a registered nurse — a physician (or an NP or PA under standardized procedures) must perform the good-faith exam and issue a patient-specific order before an RN performs the injection or laser treatment.

Ownership & corporate practice of medicine

California strongly bars the corporate practice of medicine. This is the opposite of a permissive-ownership state.

• Corporations and other artificial legal entities have no professional rights, privileges, or powers — laypersons and lay entities may not own any part of a medical practice or control clinical decisions.

  Cal. Bus. & Prof. Code §2400

• The compliant structure is a professional medical corporation under the Moscone-Knox Act: a majority of shares must be held by California-licensed physicians, only enumerated licensed health professionals may hold shares (up to 49% in aggregate), and no lay person may hold any stock.

  Cal. Corp. Code §13401.5(a)

• A lay-owned management services organization (MSO) may provide administrative/back-office services by contract, but may not control medical records, clinical hiring/firing, coding/billing, or the selection of medical equipment or drugs — doing so is illegal corporate practice of medicine.

  Medical Board of California — Medical Spas guidance

• Effective Jan 1, 2026, SB 351 bars a private-equity group or hedge fund from controlling or interfering with a practice’s professional judgment (diagnostics, referrals, treatment, coding/billing, clinical staffing, equipment), voids certain non-compete and non-disparagement clauses, and empowers the Attorney General to enforce.

  Cal. SB 351 (2025), Health & Safety Code §§1190–1192

RN / NP scope for injectables

• 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.

  Cal. Bus. & Prof. Code §2725

• Under standardized procedures, an NP (unlike an RN) may be delegated the prior good-faith exam and the ordering of the drug or device. AB 890’s autonomous-NP categories do not carve out or specially authorize aesthetic practice, and an autonomous NP remains bound by the good-faith-exam and CPOM rules.

  Cal. Bus. & Prof. Code §2837.103

Med-spa registration & licensing

• California has no dedicated med-spa license or registration category. A medical spa is legally a medical practice under the Medical Practice Act; per the Medical Board, “there are no separate laws governing these procedures,” and physicians are held to the same standard as in their routine practice.

  Medical Board of California — Medical Spas guidance; Bus. & Prof. Code §2052

Advertising rules

• A licensed practitioner may not disseminate any false, fraudulent, misleading, or deceptive communication to induce patronage — expressly reaching undisclosed altered images, unsubstantiated superiority claims, and misleading “as low as” price teasers. A violation is a misdemeanor and separate grounds for discipline.

  Cal. Bus. & Prof. Code §651

• Untrue or misleading advertising is separately unlawful as a misdemeanor, and deceptive business practices are actionable under the Unfair Competition Law.

  Cal. Bus. & Prof. Code §17500; §17200

Disciplinary landscape

• Unlicensed practice of medicine is a crime — punishable by a fine up to $10,000 and up to a year in county jail (or imprisonment under Penal Code §1170(h)) — and the same penalties reach aiding, abetting, or conspiring with an unlicensed practitioner. This is the statute that catches lay-owned spas practicing medicine and physicians who lend their license.

  Cal. Bus. & Prof. Code §2052

• The Medical Board separately disciplines its licensees (revocation, suspension, probation, fines) for unprofessional conduct — including acting without a good-faith exam, improper delegation, illegal business/CPOM arrangements, fee-splitting, and false advertising.

  Cal. Bus. & Prof. Code §2242; §651
