Step-by-step explanation:
A burn that is described as waxy white to leathery gray to charred skin that is dry and firm with absent hair, and no blanching, is classified as a third-degree burn.
A third-degree burn fully extends into the epidermis and dermis, destroying the tissue and affecting the nerve endings and sensory function. These burns may appear white, red, or black, and they require medical attention and will heal slowly without it.
Third-degree burns are serious and usually less painful than other burns because the nerve endings themselves are damaged.
