Wart removal can be a challenge, but fortunately, the most effective treatments are the least invasive. Warts grow only in the epidermis, the upper skin layer. A typical wart has a raised, rough surface.
Some, like those on the face, may be smooth and flat. The center of a wart may be flecked with dark dots; these are capillaries that supply it with blood.

Those under or around the fingernails and toenails can be hard to treat. Found mostly on the face, hands, and shins. They're less common than other warts, but when they do appear, it's often in large numbers.
Studies indicate that about half of warts go away on their own within a year, and two-thirds within two years, so "watchful waiting" is definitely an option for new warts. But some experts recommend immediate treatment to reduce the amount of virus shed into nearby tissue and possibly lower the risk of recurrence.
