Chemical peels are exfoliating solutions that are customized for different skin types and incorporate a variety of active ingredients that work to exfoliate dead skin cells and reveal a new layer of skin. Depending on the depth of the peel, different layers of the skin will be targeted and the peel may be applied differently. Superficial skin peels are applied in layers and left on your skin. They’re not timed and removed like deeper chemical peels. The strength of a superficial peel is controlled by the number of layers applied.
