Cryotherapy uses liquid nitrogen to destroy skin lesions.
It is very effective for the treatment of warts, skin tumors, pre-cancerous skin moles, nodules and skin tags.
Liquid nitrogen is a cold, liquefied gas with a temperature of 196 degrees below zero Celcius ( -321 degrees Fahrenheit.) It is used to freeze and destroy superficial skin growths.
The treated area will become red and a little tender and possibly swollen for the first few days after treatment. A scab or crust forms, which falls off by itself in one to three weeks. The skin growth will also come off with the scab; leaving healthy new skin. Sometimes multiple treatments are required.
