What is a third-degree burn?

The third-degree burn is a full-thickness burn that damages all layers of the skin and even causes injury to the underlying tissue. With a third-degree burn, the fat surrounding the skin is also involved. Sometimes the adjacent muscle and bone are affected.

The third-degree burn will appear very dry and may look white, black or a leathery brown.

This severe burn may be a painless burn as the injury destroys nerve tissue.

A third-degree burn can result in swelling and blisters. In some cases, a third-degree burn can cause the person to go into shock and even cause death.

Antimicrobial ointments are used on the third-degree burn to prevent infection. Doctors may use skin grafts or synthetic grafts to cover the burned tissue and cosmetic surgery may be necessary after time.
