After a liquid nitrogen treatment, the lump, wart or whatever is being treated will gradually discolour and fall off. The surrounding skin will sometimes become red and swollen and be sore for a day or so. It is similar to a mild burn. Occasionally a blister (sometimes a 'blood blister') forms. If this happens, it is best to pop it with a clean ...

Liquid nitrogen consist of pure nitrogen molecules (N 2) in their liquid state. At normal pressure, nitrogen becomes a liquid below −195.8° C or −320.4° F and a solid at −209.86 °C or −345.75 °F. At these low temperatures, it is so cold it immediately freezes tissues. Liquid nitrogen, like solid and gaseous nitrogen, is colorless.

Skin can freeze or adhere to surfaces cooled by liquid nitrogen, causing tearing upon removal. Nitrogen gas sublimating from liquid nitrogen can quickly displace the oxygen in poorly ventilated or closed rooms, and can cause asphyxiation. To reduce the possibility of asphyxiation, use liquid nitrogen only in well-ventilated rooms.
