Doctor Answers (1) on Facial warts
Freezing: In this treatment, a doctor will use liquid nitrogen to freeze a wart. A blister forms around the wart and the dead tissue falls off within about a week.
Cantharidin: This substance, an extract of a blister beetle and applied to the skin, forms a blister around the wart. After cantharidin is applied, the area is covered with a bandage. The blister lifts the wart off the skin so the doctor can remove the dead portion of the wart.
Other medications: These include bleomycin, which is injected into a wart to kill a virus, and Aldara, an immunotherapy drug that comes in the form of a prescription cream. Although Aldara is stated for genital warts, it is modestly effective on other types of warts.
Minor surgery: When warts cannot be removed by other therapies, surgery may be used to cut away the wart. The base of the wart will be destroyed using an electric needle or by cryosurgery (deep freezing).
Laser surgery: This procedure utilizes an intense beam of light (laser) to burn and destroy wart tissue.
