First-degree burns are the most minor burns, such as mild sunburns and scalding by hot but not boiling water. They redden the skin and cause a small amount of pain. Second-degree burns are more severe than first-degree burns and are typified by blisters and increased pain. Third-degree burns are the most severe and result in a large loss of skin and damage to the nerves in the skin, which actually can make them less painful than second-degree burns despite being far more damaging.
