Smooths, Unclogs, Brightens CLEARITY is an award-winning AHA mandelic acid serum with vitamin C & turmeric. It brightens the skin, unclogs pores, and stimulates new collagen production. Benefits: This exfoliating serum is the best weapon to unclog pores and dissolve excess oil while stimulating collagen. "The Blackhead Dissolver" got its nickname because after 10 minutes alone on your skin, you will see blackheads melt away. With a perfect acid blend, specific pH, and stabilized Vitamin C bioflavonoids, you’ll experience skin that is noticeably brighter, healthier, and free of blackheads. Because this mandelic acid serum also contains Vitamin C, you do not need a separate Vitamin C serum.
