How do you treat flat warts on your face?

Flat warts on the face should only be treated by a physician. Home remedies shouldn't be used for any type of warts on the face, according to Healthline.

The primary treatment performed by doctors for flat warts on the face is freezing with liquid nitrogen. The freezing causes a blister to form around the wart, which usually lifts away from the skin in about a week, as Healthline explains. Often, more than one liquid nitrogen treatment is needed to remove a wart. If treatment with liquid nitrogen doesn't work, a physican may choose to remove the wart surgically, either with a surgical knife or with electricity; this type of wart removal may leave a scar.
