What can I expect from liquid nitrogen treatment?

  • 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 pin and apply a plaster.

  • New skin quickly forms and any scab or blister will soon disappear. The appearance of the skin afterwards is usually good.

Does liquid nitrogen treatment always work?

Usually, it does. However, 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.
