Exert Smart Body Coolant®, The once a day spray that helps keep you cool and dry. Exert is made of PCM (Phase Change Material) and high thermal conductivity materials (moves heat rapidly) which creates a fast acting smart body coolant that recharges. Exert gets sprayed once on the body and activates only when there is a skin temperature spike. Exert doesn’t feel cold when applied but instead works by drawing heat away from the body only when the body needs it. When skin temperature rises, Exert activates and cools the skin by 2 to 6 degrees. When body temperature drops to normal, Exert recharges and is ready to cool again without the need to reapply. Whether it’s menopause, hot flashes, stress, medication, anxiety, environment, excessive sweating, or physical exertion, Exert helps regulate skin temperature.
