DEGREE OF BURNS

First-degree burns are usually limited to redness (erythema), a white plaque and minor pain at the site of injury. These burns only involve the epidermis.

DEGREE OF BURNSDEGREE OF BURNS

Second-degree burnsSecond-degree burns manifest as manifest as erythema with superficial blistering erythema with superficial blistering of the skin, and can involve more or of the skin, and can involve more or less pain depending on the level of less pain depending on the level of nerve Second-degree burns involve nerve Second-degree burns involve the superficial (papillary) dermis and the superficial (papillary) dermis and may also involve the deep (reticular) may also involve the deep (reticular) dermis layer.

Third-degree burnsThird-degree burns occur when occur when the epidermis is lost with damage to the epidermis is lost with damage to the hypodermis. Burn victims will the hypodermis. Burn victims will exhibit charring and extreme exhibit charring and extreme damage of the dermis, and damage of the dermis, and sometimes hard eschar will be sometimes hard eschar will be present. Third-degree burns result in present. Third-degree burns result in scarring and victims will also exhibit scarring and victims will also exhibit the loss of skin hair and keratin. the loss of skin hair and keratin.
