The salicylic acid content of over-the-counter wart removal medicines is 17 percent. Your doctor, however, can prescribe a higher concentration. If that doesn’t work, your physician may want to introduce you to cryotherapy. Cryotherapy involves the use of liquid nitrogen to freeze the infected skin cells. After a few freezing sessions, that stubborn wart or warts will likely fall off and, at long last, you’ll be left with your normal skin. The downside to cryotherapy is that it can be mildly uncomfortable.
Cryotherapy isn’t the only option in your doctor’s wart removal arsenal. There’s another treatment which uses the opposite approach.
