Exfoliation is a process that sloughs dead skin cells from the top layer of skin, allowing new rejuvenated skin to surface. After an exfoliation your skin absorbs moisture more easily. Maintaining moisture helps slow the aging process and produces a more glowing appearance. Regular exfoliation can also help keep acne at bay by keeping pores clear. However, not all exfoliation techniques are equal. Choose the one that is specifically design for your skin type and your skin needs.
