What does liquid nitrogen do to skin?
Liquid nitrogen has a boiling temperature of -196°C at atmospheric pressure. Direct contact can freeze the skin causing frostbite and cold burns. Delicate tissue, such as eyes, can be damaged by an exposure to the cold gas alone which would be too brief to affect skin.
What happens when dermatologist freezes skin?
By freezing the skin, a blister is created underneath the lesion. Ideally, as the new skin forms underneath the blister, the abnormal skin on the roof of the blister peels off. Occasionally if the lesion is very thick (such as a large wart), only the surface is blistered off.
