A burn is a type of injury to flesh or skin caused by heat, electricity, chemicals, friction, or radiation.Burns that affect only the superficial skin are known as superficial or first-degree burns. When damage penetrates into some of the underlying layers, it is a partial-thickness or second-degree burn.In a full-thickness or third-degree burn, the injury extends to all layers of the skin.he size of a burn is measured as a percentage of total body surface area (TBSA) affected by partial thickness or full thickness burns. First-degree burns that are only red in color and are not blistering are not included in this estimation. Most burns (70%) involve less than 10% of the TBSA.
