Very shallow, superficial burns cause only reddening while deeper burns may produce blistering, or destruction through the entire layer of skin down to the subcutaneous tissue. This picture shows 2nd and 3rd degree burns covering most of the body. Burns are difficult to treat and may require multiple surgeries over a period of years. First degree burns produce only reddening of the skin. Second degree burns produce blistering, as seen here.
