Full thickness burns destroy both layers of skin – (epidermis and dermis) and may penetrate more deeply into underlying structures. These burns have a dense white, waxy or even charred appearance. The sensory nerves in the dermis are destroyed in a full thickness burn, and so sensation to pinprick is lost. The coagulated dead skin of a full thickness burn, which has a leathery appearance, is called eschar.
Following first aid and cleansing, full thickness burns should be covered with an appropriate silver or antibacterial dressing and referred to a surgeon.
