Which of the following activities does NOT fall under the responsibilities of an esthetician?

The correct answer is that performing cosmetic surgery does not fall under the responsibilities of an esthetician. Estheticians are trained professionals focused on skin care and beauty treatments, which include a range of activities such as performing facial treatments, applying makeup, and removing body hair.

Cosmetic surgery is a medical procedure that requires highly specialized training and licensure, typically carried out by licensed medical professionals like dermatologists or plastic surgeons. Estheticians are not qualified to perform these invasive procedures, as their training emphasizes non-invasive skin care techniques, product application, and other beauty-related services rather than surgical interventions. This distinction is crucial since it helps maintain safety and ensures that clients receive appropriate care for their personal care and aesthetic needs.
