An aesthetician works at a spa or salon and gives specialized non-medical and non-invasive skin care treatments to clients. They often perform facial treatments, but body treatments such as massages, body wraps, sugaring, waxing, pedicures, and manicures can also be offered. Aestheticians may do anti-aging therapies for their clients such as microdermabrasion or gentle acid peels. More serious anti-aging treatments such as botox must be performed by a licensed medical doctor. These services can help treat skin problems such as eczema, acne, or dry skin. Aestheticians have extensive knowledge of skincare products and can create or suggest an at-home regimen for their clients.
