Cryotherapy is a great method for removing warts, and should be recommended by a dermatologist, and consists of applying a small amount of liquid nitrogen, which allows the wart to freeze and causes it to fall off within 1 week.
Warts are small lesions on the skin that are caused by the Human Papilloma Virus, HPV, and which can be transmitted directly from person to person or indirectly through the community use of swimming pools or sharing towels, for example. Find out more about warts.
How it works
The wart removal treatment must be carried out by a dermatologist, who will apply liquid nitrogen, which is at a temperature of almost minus 200ºC, on the wart to be removed. Applying the product does not hurt, as the low temperatures allow pain control.
This application is made as a spray, and allows the wart and virus to freeze, which means that it ends up falling off within 1 week. Generally, for small warts, 1 treatment session is required and for larger warts, 3 to 4 sessions may be required. With this treatment, after the wart falls off and the skin heals, the skin is smooth and scar-free.
Is the treatment effective?
This treatment is effective because liquid nitrogen allows freezing not only the wart but also the virus that causes it. Thus, the problem is eliminated from the root and the wart does not appear again, as the virus is no longer active in that location, and there is no danger of spreading the virus to other areas of the skin.
Some Cryotherapy treatments are already sold in pharmacies, such as Wartner or Dr. Scholl STOP warts products, which can be used at home following the specific instructions for each product. In addition to cryotherapy, there are other methods to remove warts which include the process of cutting or burning the wart, using laser surgery or chemicals such as cantharidin or salicylic acid, however these techniques must be recommended by the dermatologist if cryotherapy has not been effective. .
