Freezing / Cryotherapy

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.
