Which type of burn is characterized by damage to all layers of the skin?

A third-degree burn is characterized by damage to all layers of the skin, including the epidermis, dermis, and underlying tissues. This type of burn destroys the skin's outer layer completely and extends into the deeper layers, often resulting in a waxy, white, or charred appearance. Because of the extensive damage, third-degree burns can also affect nerves, which may lead to a loss of sensation in the affected area. This level of burn typically requires medical attention, and healing can be a lengthy process that may involve skin grafting or specialized wound care.

In contrast, first-degree burns are superficial and only affect the outermost layer of skin, second-degree burns involve the outer and part of the underlying layer, causing blisters and more significant pain, while fourth-degree burns extend beyond the skin into muscle and bone, indicating an even more severe level of injury.
