Scalding, burns and other accidents often occur in life. The first thing you should do after a local skin burn is not to panic, you should immediately get away from the heat source, take off the clothing soaked in hot liquid, when removing the clothing be careful not to break the blisters, if necessary, you can use scissors to cut the clothing. Immediately after getting away from the heat source, cold therapy should be given by immersing the injured area in cold water or rinsing it under the tap. Cold therapy must be adequate, at least half an hour, until the pain is not very obvious or is tolerable. After cold therapy, you should go to the local hospital burn department to deal with the trauma formally, do not apply drugs on their own, not to mention the external application of soy sauce, toothpaste, alkali surface or prescription, otherwise it is easy to cause infection, deepen the trauma, resulting in scar growth.
