Colorado Medical Board Rule 1.17 treats cosmetic injections of any substance as medical-aesthetic services, which are the practice of medicine. A physician may delegate them to someone not licensed to perform them only under the rule's conditions. Delegation to PAs and to people regulated by the Board of Nursing falls under other rules and the Nurse Practice Act.
