The GREY overnight sleeping mask works while you sleep. Strengthening, replenishing, and restoring the skin, this multi-active face mask features a 24-hour chronoactive to protect epidermal lipids. Swiss garden cress diminishes the effects of daytime stressors and thwarts melanin formation, for brighter, more luminous skin. Seed extracts reinforce the skin's internal structure, boosting its self-protecting capacity and accelerating recovery, while simultaneously repairing signs of premature aging.
