Warts can be very annoying, and although they sometimes go away on their own, they can take a long time. If you don’t want to wait, you can go for cryotherapy to remove them, including freezing them off.
Cryotherapy is one of the most common ways to remove warts. Another advantage is that it may also lower the chances that warts will spread to other parts of your body.
During treatment, a doctor directly applies liquid nitrogen, a very cold substance, to the patient’s warts. This causes warts to freeze off immediately, leading to falling out. The procedure itself is very fast, but it might hurt. This way, in some cases, the doctor may apply a local anesthetic to your wart to avoid causing pain during the cryotherapy session.
Furthermore, most warts require 1 to 4 treatments, with 1 to 3 weeks between each treatment. The best cases for this treatment are fair-skinned patients because it can cause scarring in people with darker skin, for adults or older children, as it may be too painful for small ones and if the wart is on the part of your body with no hair. Cryosurgery can cause you to lose your hair permanently in the places where it is done.
In conclusion, cryotherapy can be an effective treatment for warts that provides minimal scarring. It’s typically used if topical treatments aren’t effective alone in treating warts and are very fast and safe when done by professionals.
