This set of eye masks features three layers for maximum skin-loving benefits. Hyaluronic acid hydrates the skin to diminish the appearance of fine lines and wrinkles, aloe leaf extract offers cooling, soothing, de-puffing and awakening effects to the under-eye area, and a powerful blend of 17 amino acids helps maintain skin's hydration, texture, and overall appearance. The top layer of foil helps retain heat and prevents evaporation, allowing the serum to deeply penetrate the skin, the middle layer is elastic to prevent the masks from slipping, and the third layer is a cellulose fiber that condenses and delivers soothing ingredients to the under-eye area.
