Most small first or second degree burns heal in just a few weeks. If a small burn has been surgically closed with skin grafts, it may heal quickly. But larger wounds or more serious burns take up to three months or longer to heal. Again, burns may have varying depths, depending on the cause of the burn or the damage. One part of the burn injury may be a first or second-degree burn.
The skin swells, and underlying tissue is often exposed. Third-degree burns may have less pain than first-degree or second-degree burns. There can also be no pain when nerve endings are destroyed. Care. Third-degree burns always require emergency care. Second-degree burns need immediate care if the burn is on the face, hands, feet, genitals, or on any joint, or if the burn affects an area larger than 10 square inches. Most first-degree burns and many second-degree burns can be treated with self-care.
