Introduction: Classification of Peels

Many chemical peels and combination modalities are currently available for different clinical goals. The classification of chemical peels is defined by the depth of penetration into the skin, which can be superficial peels (corneal layer, epidermis, superficial papillary dermis only), medium-depth peels (past papillary dermis, up to upper reticular dermis), or deep peeling (all of the above but also reaching mid reticular dermis and extensive inflammation). The success of the procedure depends on the artistic hands of the surgeon and the right understanding of specific characteristics of the wounding agent. This chapter will provide important information for dermatologists and plastic surgeons with interest in chemical peels.
