The application of liquid nitrogen is used to treat skin lesions such as warts, skin tags, and keratoses.
Freezing damages the treated lesion preventing its survival. Treatment rarely requires anesthesia and almost never leaves a scar.
Liquid nitrogen is a chemical that is used to remove abnormal tissue on the skin or inside the body. Liquid nitrogen is extremely cold at around minus 328°F (minus 200°C). After we apply a small amount of liquid nitrogen to the abnormal cells, the frozen tissue dries up and falls off. Liquid nitrogen is used only to treat abnormal or cancerous tissue at a single site and not throughout your body.
