On a hot summer day, you definitely want to keep your skin moistured and look healthy. You could cover it with some expensive lotion, or use a misting system to make it less dry. Anwick Misting System quite small, but it can continuously spray after a few pumps with your hand thanks to its battery-free system.
The spray offers 20 seconds of pure misting so you can cool the surface of the skin with just a minimal initial effort. The water can be refilled regularly as needed and a string of a cord is attached to make it easier to carry anywhere.
