Chemical peel
Chemical peel
A Chemical peel (pronunciation: /ˈkɛmɪkəl piːl/) is a technique used to improve the appearance of the skin on the face, neck or hands.
Etymology
The term "chemical peel" is derived from the process itself. It involves the application of a chemical solution to the skin, which makes it "blister" and eventually peel off. The new, regenerated skin is usually smoother and less wrinkled than the old skin.
Procedure
A chemical peel is performed by applying a chemical solution such as glycolic acid, trichloroacetic acid, salicylic acid, lactic acid, or carbolic acid (phenol) to the skin. These chemicals cause the skin to exfoliate and eventually peel off. Once the old skin has peeled off, the new skin underneath is often smoother, less wrinkled, and has more even coloration.
Types of Chemical Peels
There are three basic types of chemical peels:
- Superficial or lunchtime peel: Alpha hydroxy acid or another mild acid is used to penetrate only the outer layer of skin to gently exfoliate it. The treatment is used to improve the appearance of mild skin discoloration and rough skin as well as to refresh the face, neck, chest or hands.
- Medium peel: Glycolic acid or trichloroacetic acid is applied to penetrate the outer and middle layers of skin to remove damaged skin cells. The treatment is used to improve age spots, fine lines and wrinkles, freckles and moderate skin discoloration. It also can be used to smooth rough skin and treat some precancerous skin growths, i.e., actinic keratosis.
- Deep peel: Trichloroacetic acid or phenol is applied to deeply penetrate the middle layer of skin to remove damaged skin cells. The treatment removes moderate lines, age spots, freckles and shallow scars. Patients will see a dramatic improvement in skin appearance. The procedure is used on the face and only can be performed once.
Risks and Complications
Chemical peels can cause various side effects, including redness, scarring, infection, change in skin color, and heart, kidney, or liver damage. It's important to discuss these potential risks with a healthcare provider before undergoing a chemical peel.
