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.
Cryotherapy Aftercare for 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.
