PMD Personal Microderm. Includes 6 Grey Replacement Discs (2 large body discs, 4 small facial discs) and 1 black replacement filter. Features Aluminum Oxide Crystal coated tips for a very sensitive level of exfoliation. By combining the power of exfoliation with a unique vacuum suction, the PMD works to remove the dead, dull skin cell barrier, increase blood flow, and stimulate the body's natural production of collagen and elastin. Overall, the PMD brightens, smoothes, and evens skin tone and texture, and it reduces the appearance of fine lines and wrinkles, blemishes, and enlarged pores. Put on a fresh face with PMD Personal Microderm, and say hello to gorgeous skin.
