An aesthetician is a skin care specialist who does not have a medical background, but a cosmetic one in the beauty and style industry. It is a highly specialized branch of cosmetology and would be pursued by a cosmetologist with a special interest in skin care. Aestheticians work at salons and spas and perform specialist skin treatments on clients. Most often, treatments are focused on the face but they may also perform body treatments such as body wraps, massages, waxing, sugaring, manicures and pedicures. Therapists also have specialist knowledge of skin care products and can offer advice on at-home skin care regimens and recommend specialist products to help address skin problems.
