What is the definition of an esthetician?

The definition of an esthetician is a person who performs skin care services for compensation. This includes a variety of services such as facials, skin analysis, and body treatments aimed at improving the appearance and health of the skin. Estheticians focus on beauty and skin care, which encompasses both aesthetic treatments and education about skincare practices.

The other options do not accurately define an esthetician. A specialist in cosmetic surgery primarily engages in surgical procedures, which is outside the scope of an esthetician's non-invasive services. Although a hair stylist may offer skin treatments, this does not align with the formal definition of an esthetician, as it implies a lack of specialization in skin care. Lastly, instructors teaching about skin care play a different role than practicing estheticians, as they are focused on education rather than providing direct skin care services. Thus, A captures the essence of what an esthetician does.
