How does freezing a wart with liquid nitrogen kill it?

Answer 1

You’re trying to create a blister under the wart, using the cold of liquid nitrogen to do it (sort of like frostbiting the wart). Once the blister forms, you can remove the wart (and the associated dead skin) and just have a popped blister on otherwise healthy skin.
