How Does Liquid Nitrogen Wart Removal Work?

Liquid nitrogen is a low-temperature liquid. To give you a thought of exactly how cold this liquid is, it has a boiling point of -321°F (-196°C), while water boils at +212°F (+100°C).

When the cold liquid nitrogen is splashed onto the wart, it freezes the tissue dead.

After the encompassing tissue defrosts, the injury will in the long run scab over and mend, yet that annoying wart will be no more.

There are mainly 2 ways that a wart patient can use liquid nitrogen to freeze off a wart:



Option #1: Cryotherapy Wart Removal by Doctors

Liquid nitrogen cryotherapy is what dermatologists use most often to cure warts, says the American Osteopathic College of Dermatology (AOCD).

This treatment destroys a wart by freezing it with liquid nitrogen, causes a blister to be formed. When the blister peels off, all or part of the verruca peels off as well.

While local anesthesia is usually not required, the doctor may apply anesthetic numbing cream before freezing wart off, in order to reduce the pain level during the treatment process.


You may expect a few visits to your health care provider while being treated with liquid nitrogen to get rid of a wart. This is because the liquid nitrogen might have to be applied more than a single time before the wart is totally removed.

According to the reputable Patient.info UK:

Sometimes thicker warts or verrucas need two or more sessions of liquid nitrogen treatment over a period of a few weeks to get to the root. It may work but is no more effective than over-the-counter treatment with salicylic acid.
