What condition is indicated by white, waxy skin on fingers, nose, and cheeks of a hiker?

The condition indicated by white, waxy skin on the fingers, nose, and cheeks of a hiker is deep frostbite. This severe type of frostbite typically occurs when skin and underlying tissues freeze due to prolonged exposure to cold temperatures. The affected areas can take on a pale, waxy appearance, indicating significant tissue damage.

In deep frostbite, not only does the exterior skin freeze, but it can also impact deeper tissues, leading to numbness and a greater risk of permanent damage. This contrasts with superficial frostbite, where only the skin's surface is affected and may appear red or white without the significant tissue damage. Cold shock and cold stroke are conditions related to the body's response to cold exposure but do not specifically refer to the tissue damage and external appearance indicative of frostbite.
