Get it here: Mary Kay Clear Proof Deep-Cleansing Charcoal Mask
 
Clarify acne-prone and oily skin with Mary Kay's top-performing face mask, a GH Seal star and Beauty Award winner. Made with two types of clay, it reduced skin’s oil 89% and shine 84% in 15 minutes, GH Beauty Lab data analysis found. Even though it has intense purifying effects, it doesn't dehydrate skin, instead leaving it "silky and soft," a Lab tester reported.
