Corns and Calluses








What are corns and calluses?

A corn is hard, thickened skin that can occur on the top, between or on the tip of the toes. A callus is similar, but is larger and usually occurs across the ball of the foot, on the heel, or on the outer side of the big toe. “Soft” corns are corns that absorb and hold moisture. They’re usually found between the smaller toes.

What causes corns and calluses?

Corns and calluses are your skin’s way of protecting you. Hard layers of dead cells are produced when skin undergoes excessive pressure or friction. For example, where one toe rubs against the other a corn often forms. The thicker the corn or callus becomes, the morn pain and burning it may cause as it increases pressure on living tissue underneath.
