What Is Cryotherapy?

Cryotherapy is the method of using liquid nitrogen to destroy abnormal or diseased tissue present on the skin. At Helena Dermatology, we frequently use this treatment to remove precancerous spots, warts, and other abnormal skin growths. This treatment method is highly effective due to its speed of application and results. In some cases, blisters from the treatment fall off and heal within a couple of weeks. 


How Does Cryotherapy Work?

Cryotherapy works through the application of liquid nitrogen directly to the skin. Liquid nitrogen is a cold, liquefied gas with a temperature of -196oC (-321oF). Due to its low temperature, this substance can freeze and destroy superficial skin growths. The application process requires no preparation before treatment and can be used for a range of different skin concerns.

What Does Cryotherapy Address?

Some of the most common ways we use this cryotherapy is for the removal of skin tumors, moles, precancerous growths, skin tags, warts, and clusters of tissue (nodules). This treatment option can also be used to remove unattractive freckles or other spots on the skin. Though the treatment can feel uncomfortable, the application of liquid nitrogen to the skin has no side effects aside from a brief burning sensation at the treatment area.

What to Expect During Your Visit

Upon your arrival to our center, we will assess your condition to determine whether or not cryotherapy is right for you. If so, the process will begin with the application of liquid nitrogen to your treatment area. The chemical is typically applied using a cotton swab or a spray canister when treating growths on the outside of your body. We apply the liquid nitrogen to the top layer of your skin growth. The substance instantly freezes the growth as well as a little bit of the tissue surrounding it. You may feel some burning or stinging during this process, but the treatment is generally described as tolerable.

Results From Cryotherapy

Following cryotherapy, a blister forms over the treated growth and surrounding skin within 3-6 hours. The blister might bleed and turn dark purple or black; this reaction is entirely normal. The blister will then flatten within 2-3 days and should fall off within 2-3 weeks after your visit. Several cryotherapy sessions may be necessary for best results depending on your specific condition.
