A callus (or callosity) is a toughened area of skin which has become relatively thick and hard in response to repeated friction, pressure, or other irritation. Rubbing that is too frequent or forceful will cause blisters rather than allow calluses to form. Since repeated contact is required, calluses are most often found on feet because of frequent walking. Calluses are generally not harmful, but may sometimes lead to other problems, such as skin ulceration or infection.
Corns and Calluses. A corn is a protective layer of dead skin cells that forms due to repeated friction. It is cone-shaped and has a knobby core that points inward. This core can put pressure on a nerve and cause sharp pain. Corns can develop on the top of, or between, toes.
