What’s the difference between dermatology, cosmetology, and esthetics?

Dermatology is a branch of the medical profession, practiced by licensed physicians who specialize in disorders of the skin. Esthetic practice specifically excludes diagnosis, prescription, or any other service, procedure, or therapy that requires a medical license. If you’re being treated by a dermatologist, your esthetician can provide complementary and support therapies. In addition, estheticians are trained to recognize early signs of many medical conditions affecting the skin, and will refer you to a dermatologist in such a case.

Cosmetology is the study of beauty treatments including nail care, hair care and styling, makeup application, skin care and more. Esthetics is one branch of cosmetology; some estheticians work in other branches of cosmetology in addition to their skin care practice.
Techniques and products

Techniques used by estheticians include facial steaming, wrapping, exfoliation, waxing, pore cleansing, extraction, and chemical peels. Creams, lotions, wraps, clay or gel masks, and salt scrubs are used. Machines may also be used to help deliver high-tech services.

Some common therapies:

Chemical peel: An exfoliation process, very effective in treating a large range of skin concerns such as aging, sun damage, acne, mild scarring, improving overall skin brightness and evening skin tone. Peels can be light, moderate or deep. Light peels require no down time from work or normal activities. Moderate peels may require a day or two of down time, and deep peels can require a week or more to allow the skin to fully heal. Estheticians who are not working in a medical setting perform light to moderate peels only. Deep peels are performed by a physican, or under a physician’s supervision, for your safety.

Exfoliation: The removal of dead skin cells manually (scrubbing, brushing, or using a system such as microdermabrasion), with a chemical peel (a product that causes dead skin cells to shed) or with an enzymatic product that digests dead skin cells.

Extraction: This is the process of deep cleansing the pores, either manually (using gloved hands and cotton or tissue around the fingers, with gentle pressure to remove the impacted pore) or using a metal extraction implement designed to clear blocked pores. This can also include the use of a lancet (a small sharp blade to lift the dead cells of the skin prior to extraction).

Facial: A facial is the most popular treatment performed by estheticians. It is a good way for your therapist to get a good understanding of your skin prior to suggesting more aggressive treatments. A facial generally includes makeup removal and skin cleansing, exfoliation by mechanical, enzymatic or chemical means, steaming, extractions, facial massage, a treatment mask, serum/moisturizer and sunblock. For most people, facials can be scheduled every four weeks, although your therapist may recommend a different schedule based on your individual needs.

Microdermabrasion: The process of resurfacing the skin using a machine that sands the skin’s epidermal (outer) layer, using either a wand tipped with crushed diamonds, or a spray of special crystals which are then suctioned back up along with the dead skin cells. It can be very helpful in improving skin texture, fine lines and the effectiveness of home care product penetration.

Waxing: Waxing removes unwanted hair at the root. There are two different types of waxes: hard and soft. Soft wax is applied warm to the skin in a thin layer in the direction of hair growth. Cloth strips are then applied to the warm wax, rubbed in the direction of hair growth, and quickly pulled off in the opposite direction. This method is best used on larger areas of the body such as the legs, back or chest. Hard wax is used without cloth strips. It is applied warm, in a layer about the thickness of a nickel, allowed to dry and then removed quickly in the opposite direction of hair growth. Hard wax is less irritating to sensitive skin and is excellent for the bikini, underarm and facial areas.
