Peels, in the context of skin care, refer to treatments that remove the outer layers of skin to improve its appearance and texture. These treatments can be chemical, using acids to exfoliate the skin, or physical, involving the use of abrasive materials. Peels are commonly used to address issues like acne, sun damage, and fine lines, promoting a smoother and more youthful complexion. There are different types of peels, including superficial, medium, and deep peels, each varying in intensity and recovery time. Superficial peels, often containing ingredients like glycolic acid, are gentle and require little downtime, while deep peels, such as those using trichloroacetic acid, may necessitate longer recovery periods.
