The treatment of burns depends on the depth, area and location of the burn. Burn depth is generally categorised as first, second or third degree. A first degree burn is superficial and has similar characteristics to a typical sun burn. The skin is red in colour and sensation is intact. In fact, it is usually somewhat painful. Second degree burns look similar to the first degree burns; however, the damage is now severe enough to cause blistering of the skin and the pain is usually somewhat more intense. In third degree burns the damage has progressed to the point of skin death. The skin is white and without sensation.
