Description

Common warts are rough, raised, skin-colored growths that typically appear on the hands and fingers, often around the nails. They're caused by HPV entering through small breaks in the skin and are most frequent in children and young adults.

Causes

Direct infection of the skin with human papillomavirus, usually through a small cut or hangnail.

Prevention

Avoid picking at hangnails, and don't share nail clippers or bite your nails, since these habits create easy entry points for the virus.

Treatment Options

Salicylic acid, cryotherapy, or in-office minor procedures for warts that resist home treatment.

Myths vs. Facts

Myth: Duct tape alone will cure a wart overnight. Fact: It isn't an instant fix, and controlled studies have found duct tape works no better than a placebo bandage -- salicylic acid remains the better-supported first step.

When to See a Dermatologist

If a wart persists after several weeks of consistent OTC treatment.
