The job responsibilities of a cosmetic nurse injector focus on performing aesthetic injections. In addition to providing injections of Botox, which is meant to reduce facial wrinkles, you assess patients to ensure their suitability for non-surgical treatments, such as Botox, dermal fillers, laser hair removal, or chemical skin treatments. You assess the patient after the injection as well and provide them with relevant information about the procedure and possible side effects. A cosmetic nurse injector can perform their duties in an aesthetic surgery facility, a medical spa, or a skin clinic.
