Peels, in the context of skin care, refer to treatments that remove the outer layers of skin to improve its appearance. They can be classified into three types: chemical peels, physical peels, and laser peels. Each type uses different methods and substances to exfoliate the skin, helping to reduce issues like acne, wrinkles, and uneven skin tone. The process of a peel typically involves applying a solution or using a device to slough off dead skin cells. This encourages new skin growth and can enhance the skin's texture and brightness. Peels are often performed by dermatologists or licensed estheticians for safety and effectiveness.
