Unlike traditional cooling methods such as applying a wet flannel, Kool 'n' Soothe stays in place, so you or your child can get up and move around while still getting relief. Kool 'n' Soothe is a hypoallergenic, non-medicinal product that can be used in conjunction with other medication. How it works The Kool 'n' Soothe strip contains a high percentage of water (roughly 70%) which works with the body's natural cooling system. As the surface temperature of the skin rises, the heat of the skin causes the evaporation of the water held within the Kool 'n' Soothe gel sheet - this creates a cooling sensation on the skin. The excellent heat transfer ability is made possible by the gel's unique structure which disperses heat freely, and maintains a steady and constant cooling effect that lasts up to eight hours. Kool 'n' Soothe for Fever Convenient and easy to use, Kool 'n' Soothe Fever is a cooling gel strip which adheres to your child's forehead and gently cools.
