Exfoliation has many benefits. The most obvious is the elimination of the dead skin, which allows cosmeceutical treatment products to better penetrate the skin. By removing this layer, called the stratum corneum, irregular pigment can be tackled, too. You’ll also see improvement in the skin’s overall appearance and texture. Microdermabrasion goes deeper than other modes of exfoliation to help the skin replenish itself by stimulating cell regrowth.
