Freezing warts

Freezing warts at home

Freezing a wart at home is cryotherapy using a very cold substance. Cryotherapy is a common treatment for warts and can be done in a doctor’s office or using various products available over-the-counter. The freezing of the skin causes damage to the cells housing and protecting the wart. The wart can develop a blister underneath and makes the wart falls off. Or damaged skin cells are discarded by the body, including the tissue of the wart and virus infected tissue. The application usually takes less than a minute and results are seen within one or two weeks.
After treatment the wart naturally falls off within a couple of weeks. The treatment is considered very safe and there is little risk of scarring. Recently, advanced versions have been made in the use of Cryotherapy. These advanced versions freeze the wart with millimeter precision, thereby causing less discomfort and minimizing any freezing of the surrounding skin.


Cryotherapy warts Liquid nitrogen

Cryotherapy is the standard treatment for wart removal and has been successfully used for many years by health care professionals. Traditionally liquid nitrogen has been used to freeze the wart, thereby destroying the tissue and the blood supply to the wart. 

Cryotherapy is a standard treatment for warts and can be done by a GP. The liquid nitrogen application usually takes less than a minute. Your doctor may trim the wart with a small knife before applying liquid nitrogen. Cryotherapy with liquid nitrogen is painful. A numbing local anesthetic is usually not needed but may be used in some cases. Your GP applies the liquid nitrogen to the wart using a probe or a cotton swab. Liquid nitrogen can also be sprayed directly on the wart.

Most warts require 1 to 4 treatments, with 1 to 3 weeks between each treatment. Usually only one or two treatments are needed for effective wart removal. Cryotherpay is a painless procedure with only a slight stinging sensation felt during treatment. Follow up treatments may be needed for stubborn warts.
