California
Medical oversight overview
According to the Medical Board of California, medical spas are considered marketing vehicles for medical procedures rather than standard day spas. Medical treatments such as injections, lasers, and chemical peels must be performed by qualified medical professionals, including licensed physicians or registered nurses and physician assistants operating under physician supervision. Additionally, medical spas offering medical procedures must be owned by licensed physicians. Consumers are strongly advised to verify provider credentials and ensure proper physician oversight before undergoing any aesthetic procedures.
