essential part of your body and is its largest organ.Your skin acts as a barrier against disease，toxins，and the suns rays.It also helps control your body temperature，prevents your body from losing too much water，warns you when things are too hot or cold，and gives you your sense of touch.As you can imagine，getting burnt can lead to very serious injuries.The first and most important step in the
