Cryotherapy freezes off surface blemishes with liquid nitrogen.

By Zeel Editorial Staff, Last updated: June 26, 2012

Cryotherapy freezes off surface blemishes with liquid nitrogen. The procedure is used for warts, keloid scars, lentigos (small benign brown spots), skin tags, and abnormal sun spots.

Cryotherapy chills targeted tissues with temperatures that fall around negative 350 degrees Fahrenheit, causing them to freeze and crystallize. When the ice crystals melt, they take the blemishes with them.

What It's Good For

Cryotherapy may be able to remove warts, keloid scars, skin tags, and small discolorations. The treatment can be used anywhere on the body where a wart or lesion has appeared.

Who it works for: Cryotherapy is best for superficial warts that are less than 10 millimeters in diameter.

Recommended age range: Cryotherapy can be used on patients of all ages.

When will I see results?: The overall treatment can take over 10 weeks from start to finish. Wounds on the head and neck heal in about four to six weeks. Those on the body may take longer to disappear.

Wart removal may take numerous treatments. Each appointment is scheduled in one to three week intervals.

Some treatments may be covered by medical insurance.

How long it lasts: After a series of treatments, cryotherapy can eliminate most skin growths permanently. They can't, however, prevent the appearance of future growths.

Key benefits of Cryotherapy: Succcessful treatment can remove warts without scarring. When performed by a skilled physician, recurrence of warts or other ugly tissues is less than 10%.

Licensed uses: Cryotherapy destroys benign skin growths like warts, pre-cancerous lesions, and keloid scars.
