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.
How long does it take a second or third degree burn to heal completely? I got a burn last year when my pants caught fire. The size of the burn it's about the size of a quarter. Now, after months my burn looks red underneath my skin.
