Brighten: Combine 2 Tbsp sour cream with 2 Tbsp honey and 1 Tbsp apple cider vinegar or lemon juice. Apply to your cleansed face and leave on for 20 minutes. Rinse with tepid water followed by a cool (not cold) rinse. This mask can be done twice a week. “This mask heals, exfoliates, brightens and moisturizes skin. It refines pores, fades acne marks and prevents blemishes from coming up,” says Macan-Graves.
