Neutrogena Night Mask Cream helps reduce signs of fatigue and maintains skin moisture. Developed in collaboration with dermatologists, it contains hyaluronic acid. Long days can take a toll on your facial skin, and no matter how much you sleep, your skin may appear more tired with each passing day. The night mask cream is designed to break this cycle of noticeable fatigue on your facial skin: it helps fade signs of tiredness, the gel formula wraps your skin in a thin, soft layer, immediately hydrates the skin with moisture night after night, and helps maintain skin's moisture. The combination of the moisturizing action of hyaluronic acid and skin stabilizing agents helps strengthen the skin's protective barrier against water loss.
