Warts are benign (not cancerous) skin growths that appear when a virus infects the top layer of the skin.
Warts are often skin-colored and feel rough, but they can be dark (brown or gray-black), flat, and smooth.
A dermatologist may use one of the following treatments:
Cryotherapy: For common warts in adults and older children, cryotherapy (freezing) is the most common treatment.
Electrosurgery and curettage: Electrosurgery (burning) is a good treatment for common warts, filiform warts, and foot warts.
Laser treatment: Laser treatment is an option, mainly for warts that have not responded to other therapies.
Chemical peels: When flat warts appear, there are usually many warts. Because so many warts appear, dermatologists often prescribe “peeling” methods to treat these warts
