GlamGlow YouthMud Tinglexfoliate Treatment Mask

It may seem counterintuitive to slather on something that looks like dirt, but this treatment mask—a favorite on Hollywood sets for its brightening abilities—purifies the skin without stripping its natural oils. Bonus: It has powerful antioxidants that help fight wrinkles and other signs of aging.
