California medical director requirements for med spas

Physician supervision & delegation in California

California restricts delegation of injectable and laser cosmetic procedures to appropriately licensed personnel under genuine supervision. For elective cosmetic laser/IPL procedures performed by licensed health care providers within their scope, a physician with relevant training and expertise must be immediately available.

• 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.

• Whenever an elective cosmetic procedure involving a laser or intense pulse light device is performed by a licensed health care provider acting within the scope of their license, a physician with relevant training and expertise shall be immediately available — defined in the rule as contactable by electronic or telephonic means without delay, interruptible, and able to furnish assistance and direction throughout the procedure and to inform the patient of post-procedure care provisions. Those provisions must sit in the provider’s standardized procedures or protocols.

• The Physician Assistant Board’s February 2026 statutory compilation states that a physician and surgeon shall not supervise more than eight physician assistants at any one time, except as provided in the emergency provision of BPC §3502.5. The compilation records the §3516 amendment by AB 1501 as effective January 1, 2026.

• Wherever the physician is, distance is itself a limit: the Board requires physicians to be within a geographical distance that enables them to effectively provide supervision and support when needed or upon request, and to be reachable and able to give guidance if an emergency arises or the patient needs a level of care only the physician can provide.

• The state board's bulletin says that “The Board of Barbering and Cosmetology (Board) would like to remind its licensees that the practice of Micro Needling/Derma Rolling is not within the scope of practice for any Board licensee.” The bulletin describes the procedure as one that involves using a small roller with fine micro needles over the skin, producing micro punctures in the skin. The Board treats it as an invasive procedure.

• ✅ California writes the limit into the definition of skin care, in tissue terms. The practice of skin care is “giving facials, massaging, stimulating, exfoliating, cleansing, or beautifying the face, scalp, neck, hands, arms, feet, legs, or upper part of the human body by the use of hands, esthetic devices, cosmetic products, antiseptics, lotions, tonics, or creams for the purpose of improving the appearance or well-being of the skin that DO not result in the ablation or destruction of the live tissue.” California permits esthetic DEVICES by name — and then bounds every one of them by what it does to live tissue.
