The laser light heats up the blood in the tiny vessels inside the wart and destroys the vessels. Without blood, the wart dies and falls off. The laser’s heat may also attack the virus that causes the wart.

Laser surgery uses an intense beam of light, or laser, to burn and destroy the wart tissue. It is usually done in a doctor’s office or clinic. Local or general anesthetic may be used, depending on the number of warts to be removed or the size of the area to be treated.
