Who may operate a cosmetic laser in California?
Oversight · part of The Practice Perimeter
Short answer
Only a physician or, by delegation, a registered nurse, nurse practitioner, or physician assistant under genuine supervision — estheticians, cosmetologists, LVNs and unlicensed staff including medical assistants may not, regardless of training.
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.

Related California rules
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.
