What is cryotherapy?
Cryotherapy (cold therapy or “freezing”) is a well-tested and very effective treatment method in dermatology. Skin changes are selectively destroyed by targeted freezing and slow thawing.
How does cryotherapy work?
Liquid Nitrogen (N2-Liquid):
A cotton swab is first dipped in liquid nitrogen and then pressed directly onto the area to be treated for a few seconds. After thawing the lesion, this process can be repeated depending on the thickness or nature of the lesion.
With special devices, which have a cooling metal attachment of different sizes, skin changes can be frozen in a targeted manner.
Using a special container with a spray nozzle and trigger, liquid nitrogen can be applied even more precisely to the skin.
Carbon dioxide capsules (CO2):
Here, CO2 is applied as a cooling medium via cartridges, as they are also used to produce soda water, mostly via handy devices by pressing a trigger. The temperature reached is about half that of using nitrogen.
Blistering occurs as a side effect, whereby the treated tissue is rejected. A crust forms, which falls off after 10-14 days.
What can be treated with cryotherapy?
Early childhood hemangiomas respond particularly well to contact cryotherapy at around -30 °C. The treatment is minimally invasive and there is scar-free healing.
