By using Water-Jel for cooling burns and scalds the heat is transferred from the skin surface into the gel. The temperature in the burn wound decreases very fast which results in a quick pain relief and reduction of the skin destruction. In the gel layer a heat flow (convection) starts. The heat energy gets spread all over the whole gel surface. At the gel surface the heat gets out of the gel by the evaporative cooling mechanism. The buffer effect of the gel layer leads to a rapid local heat transfer out of the burn wound without losing temperature around the area of usage. The risk of inducing hypothermia is reduced.
