Cooling Clouds are poised to revolutionize the way we care for tired, puffy eyes. Powered by MISSION Hydroactive™ Technology, these patented, water-activated cloth patches cool under-eyes for instant rejuvenation and depuffing. Unlike most cooling eye patches, Cooling Clouds need no pre-freezing or cooling in the fridge, and they are free of harsh or drying chemicals. All you have to do is saturate them with water, twist or snap them to activate the cooling technology, and place them under the eyes. The cloths naturally suction to the face when applied wet to stay in place. The Clouds maintain a refreshing temperature up to 30 degrees Fahrenheit below the average body temperature, effectively soothing puffiness and reducing dark circles.
