A burn is a type of injury to skin , or other tissues, caused by heat, electricity, chemicals, friction, or radiation. Burns that affect only the superficial skin layers are known as superficial or first-degree burns. When the injury extends into some of the underlying layers, it is described as a partial-thickness or second-degree burn. In a full-thickness or third-degree burn, the injury extends to all layers of the skin. A fourth-degree burn additionally involves injury to deeper tissues, such as muscle, tendons, or bone.
