AHC Premium Vital C Complex Mask is a luxurious face mask that will leave your skin with amazing brightness while also repairing and nourishing your skin. The mask contains citrus extracts rich in vitamin C, which brightens dull and hyperpigmented skin and also helps reduce dark spots and acne scars. This mask also contains sodium hyaluronate, niacinamide, and rose water among many other beneficial ingredients that help the skin lock in moisture, tighten pores, and revitalize the skin! This mask also provides a cooling effect as the nutrients rejuvenate, soothe and nourish the skin. How to use: Cleanse your face by prepping your skin with toner. Unroll and spread the sheet mask over your face. Remove after 20-25 minutes and smooth out gently to allow complete absorption. For best results, store in the refrigerator 20 minutes before using the mask. The thermometer icon behind the package turns green when it is properly cooled and ready for use.
