How does Wartner Cryotherapy work?

Wartner Cryotherapy works in a similar way to the liquid nitrogen freezing method used by GPs. The freezing agent is applied to the foam applicator; you then freeze the wart or verruca by applying the saturated foam applicator for a few seconds. As a result of this freezing, the growth should fall off after about 10-14 days. Wartner Cryotherapy is not harmful to the environment.
