Third-degree burns occur when the epidermis is lost with damage to the subcutaneous tissue. Burn victims will exhibit charring and extreme damage of the epidermis, and sometimes hard eschar will be present. Third-degree burns result in scarring and victims will also exhibit the loss of hair shafts and keratin.
These burns may require grafting. These burns are not painful, as all the nerves have been damaged by the burn and are not sending pain signals; however, all third-degree burns are surrounded by first and second-degree burns, which are painful.
