Cryotherapy is an approved treatment option for removing facial warts. However, this treatment is generally reserved for severe warts and is not the most common form of therapy, according to Dermnetnz.org.
Cryotherapy is the process of destroying warts through contact with liquid nitrogen. FamilyDoctor states that there are other remedies that may be more appropriate for the removal of a facial wart, depending on the severity of the growth. A more common form of therapy is the application of an over-the-counter product called salicyclic acid. This treatment peels away the layers of the wart until the growth is gone.
Another form of treatment for facial warts is the application of a cantharidin solution. This chemical removes the wart by blistering and therefore must be applied by a physician.
