Chemical peels are used to treat different skin problems such as acne, sun spots, fine lines, wrinkles, and uneven skin tone and texture. They involve the use of chemicals such as glycolic acid, salicylic acid, Jessner's solution, trichloroacetic acid (TCA) and phenol.
The chemical is applied to your skin and then removed after some time. The top layer of your skin peels off as a result, revealing newer, more youthful-looking skin. TCA and Jessner peels are two popular types of chemical peels.
