California treats injections, lasers and medical-grade peels as the practice of medicine, wherever they're done. The Medical Board of California says those treatments must be performed by a physician, or by a registered nurse or physician assistant under a physician's supervision. Unlicensed staff, including medical assistants, may not inject Botox. Cosmetologists, though licensed for facials and similar work, may never inject the skin or use lasers. The board also says a med spa offering medical procedures must be owned by physicians, and that a supervising doctor doesn't have to be on site but must be immediately reachable. You can check licenses through the board's license lookup.
