Chemical peeling is a treatment that has been used for decades. Essentially, it is applied to the face so that the body can regenerate the skin in better condition. There are different types of chemical peel. The one most commonly used by doctors is glycolic acid-based. Chemical peels are recommended to improve skin quality, for example, in cases of sun damage, uneven pigmentation, keratoses, dilated pores or acne scars. Recovery is very rapid, as the skin is slightly pink for around 24 hours. A series of treatments spaced about 4 weeks apart is usually preferable.
