Aestheticians are licensed professionals who are experts in maintaining and improving skin. An aesthetician’s general scope of practice is limited to the epidermis (the outer layer of skin). Aestheticians work in many different environments such as salons, medi-spas, day spas, skin care clinics, and private practices.
Aestheticians may also specialize in treatments such as microdermabrasion, microcurrent (also known as non-surgical “face lifts”), cosmetic electrotherapy treatments (galvanic current, high frequency), LED (light-emitting diode) treatments, ultrasound/ultrasonic (low level), and mechanical massage (vacuum and g8 vibratory).
An aesthetician may undergo special training for treatments such as laser hair removal, permanent makeup application, light chemical peels, eyelash extensions, and electrology. In the US, aestheticians must be licensed in the state in which they are working and are governed by the cosmetology board requirements of that state.
Aestheticians must complete a minimum 260–1500 hours of training and pass both a written and hands-on exam in order to be licensed in a given state. Utah, Virginia and Washington are the only states at this time to adopt the Master Esthetician License. Additional post graduate training is sometimes required when specializing in areas such as medical esthetics (working in a doctor’s office). Aestheticians work under a dermatologist’s supervision only when employed by the dermatologist’s practice.
Aestheticians treat a wide variety of skin issues that are cosmetic in nature, such as mild acne, hyperpigmentation, and aging skin; therefore, clients with skin disease and disorders are referred to a dermatologist or other medical professional. Aestheticians are also referred to as beauticians within North America.
Cosmetology is the study and application of beauty treatment. Branches of specialty include hairstyling, skin care, cosmetics, manicures/pedicures, non-permanent hair removal such as waxing and sugaring, and permanent hair removal processes such as electrology and intense pulsed light (IPL).
Cosmetologists are trained and licensed to perform cosmetic treatments to the hair, skin, and nails. This can be expanded into multiple parts including cutting and chemically treating hair, chemical hair removal, fashion trends, wigs, nails and skin care, skin and hair analysis; relaxation techniques including head, neck, scalp, hand and feet basic massage and aroma therapies; plus ability to expertly apply makeup applications to cover or promote and can expand into further specialties such as reflexology; theatrical applications;
