Hyperpigmentation, dark spots, or uneven skin tone occurs when there is an overproduction of melanin, the pigment responsible for skin color, in certain areas of the skin. The acids used in our new Clearly Corrective Daily Peel work by breaking down the bonds between dead skin cells and promoting their shedding. This exfoliation process helps to remove the top layer of the skin where excess melanin may be present, revealing fresher, more evenly toned skin underneath. As with all exfoliating products, SPF should always be used during sunlight exposure to reduce additional damage caused by UV rays.
