About Cryosurgery (Liquid Nitrogen Freezing)

Liquid nitrogen is extremely cold (-350 F). When it is applied to or sprayed on the skin, it rapidly freezes the top skin layers. It will sting and then itch as the skin thaws out. The treated spot will swell and then form a crust or scab. In some instances, a blister will form. The spots will look like bug bites, then scab over, fall off and leave a pink smooth spot. The healing may take two to four weeks.

If a spot is treated near your eyelid, your lids may swell and look puffy for a few days. This is common and expected.

Skin Care After Cryosurgery:

  1. Wash skin as usual every day.
  2. Do not pull the scab off. If a blister forms, try not to pull the blister roof off for 48 hours. If the roof is still intact after 48 hours, and the site is uncomfortable, you may take a sterile needle and puncture the blister to let the fluid out (again, trying not to pull the roof off).
  3. Once daily, clean with mild soap and tap water. Pat dry and apply a thin layer of Aquaphor ointment or antibiotic ointment.
  4. If the site oozes or drains, you may put a bandage over it.
  5. Call the office if you have any questions, or if the lesion treated has not resolved within three to four weeks.
