A callus is a rough, thickened area of skin that results from repeated pressure.  Skin cells of the stratum germinativum that are subject to pressure repeatedly are stimulated to produce new skin cells more rapidly.  These skin cells build up more rapidly than they can be removed through natural processes. The most common areas for a callus are the palms and soles.  Nonetheless, a callus may form anywhere repeated pressure on the skin is applied. Calluses help protect the skin from further injury or the formation of a blister. A callus requires no treatment.
