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. Watch breakouts and fine lines disappear as your skin tone brightens dramatically. Works very well for Melasma also. PRO TIP: CLEARITY must sit alone on bare skin for at least 10 minutes to do its job. Failure to leave it alone will neutralize it and you will not see the desired effect. Simply apply a thin layer all over, go do something else for at least 10 minutes, then follow with next step. Do not rinse off!
