The plant-derived sheet mask is made of environment-friendly and skinfriendly material extracted from 100% aloe. Instead of distilled water, the mask contains Birch Sap, which shows higher rate of absorption into skin than water. It keeps skin moisturized for long hours as Tremella fuciformis (Mushroom) Extract locks in moisture. Use one sheet of this plant-derived mask before going to bed to have moisturized skin.
