Facial peels are common exfoliating methods for improving the health and appearance of skin. Regular cell turnover and exfoliation is important to healthy skin. Skin recovery slows with aging, as well as exposure to ultraviolet (UV) rays and other environmental conditions. This slowing leads to a buildup of dead surface cells, a dull complexion, and impaired barrier function. Chemical exfoliants help to facilitate the release of impacted cells leaving a healthy, even complexion.
