Burn: Symptoms & Signs

Medically Reviewed on 9/10/2019

A burn is damage to the skin or other body parts that is caused by extreme heat, flame, contact with heated objects, or chemicals. Medically, the depth of a burn is categorized as first, second, or third degree depending upon its severity.

Signs and symptoms of a burn depend upon the degree of severity. First-degree burns are similar to a sunburn and cause skin redness, peeling, mild to moderate pain, and tenderness. Blistering may occur. Second-degree burns have more severe symptoms and signs, including a greater degree of blistering and more intense pain. In third-degree burns, there is loss of color of the skin as it turns white. Loss of sensation is an associated symptom with third-degree burns.
