Cryotherapy, using liquid nitrogen, creates a superficial chemical burn. This is used to destroy multiple types of benign and even precancerous lesions on the skin.

What To Expect

  • Anticipate redness, with itching or burning pain initially. Tylenol (if you are able to take Tylenol) or cold compresses can help with any significant discomfort.
  • Blisters may occur at the treated area(s) over the next few days. The blister may be clear or bloody, and may begin to weep or drain.
  • After lesion heals, skin may be slightly darker or lighter at treatment site; this typically fades in a few weeks.

Care of Treated Area(s)

  • Wash gently each day, but do not scrub.
  • Apply Vaseline frequently to minimize irritation and reduce scab formation.
  • If the blister is tense and uncomfortable, you may clean with alcohol and puncture with a sterile (cleansed in alcohol) needle. Wear gloves, or wash hands immediately before and after this procedure.
  • If open or draining, you may apply Polysporin antibiotic ointment or Vaseline and a bandage, if needed.
  • Do not pick at or pull off scab. Allow to completely heal.

Return to Clinic

  • If lesion is persistent 3 to 4 weeks after treatment, please return to clinic for additional treatment.
