When warts show resistance to salicylic acid, bandages, duct tape and even liquid nitrogen, it’s time to try a “bottom-up” approach. Rather than dry out or freeze the infected skin itself, your doctor may focus on the skin below the wart. The chemical Cantharidin causes healthy skin to blister. By soaking the wart in Cantharidin, your doctor can cause blistering of the healthy skin beneath the wart. When that healthy skin dies it destroys the foundation that the wart is connected to. The dead, blistered skin and the wart will come off together.
In rare cases, warts may need alternative treatments including surgery. Click ahead to learn more.
