With the encouragement and support of friends and family, I created Kool Relief using the principles of Thermodynamics. Kool Relief instantly relieves radiation burns by rapidly cooling your skin. Kool Relief is a medical grade aluminum disk that draws heat out of your skin and releases it into the air. You don’t need a prescription, batteries, creams or gels. It always stays cool and is ready-to-use. It's portable, and it lasts forever..
