Which type of burn affects all layers of the skin?

A third-degree burn is identified by its impact on all layers of the skin, including the epidermis, dermis, and subcutaneous tissue. This type of burn typically results in a complete destruction of the skin's layers, which can lead to a loss of sensation in the affected area due to damage to nerve endings. The skin may appear white, charred, or leathery, and it often requires medical intervention such as skin grafts for healing, as the body cannot repair itself sufficiently due to the extent of the damage.

Understanding this classification of burns is critical for wilderness first aid responders, as it allows them to prioritize treatment effectively and recognize the severity of injuries requiring professional medical attention. In contrast, first-degree burns affect only the outer layer of the skin, second-degree burns involve the outer and part of the inner layer, and superficial burns are limited to the epidermis, all of which present with less severe symptoms and healing processes.
