What is the purpose of a chemical peel?

The purpose of a chemical peel is to remove outer layers of the skin. This cosmetic procedure uses chemical solutions to exfoliate the skin, promoting the shedding of damaged or aged skin cells. This process can help improve the appearance of various skin issues, such as acne scars, age spots, and fine lines, by revealing healthier skin underneath. The removal of these outer layers leads to increased cell turnover, which can enhance skin texture and overall tone, making it appear more youthful and radiant.

The other choices do not accurately describe the primary function of a chemical peel; they pertain to different dermatological treatments or skin conditions. For instance, treating skin infections involves different approaches, and increasing pigmentation or preventing itching does not relate to the main intent of performing a chemical peel.
