What causes corns and calluses to develop?
Hyperkeratosis simply means thickening of the skin.
This thickening occurs as a natural defense mechanism that strengthens the skin in areas of friction or
excessive pressure. Abnormal anatomy of the feet, such as hammertoe or other toe deformities, can lead to corn or callus formation as can bony prominences in the feet. Footwear that is too
short or too tight or that exerts friction at specific points can also cause skin thickening that leads to corns and calluses. Abnormalities in gait or movement that result in increased pressure to specific areas can also be the cause.
It can be hard to know why finger corns develop since they often don't appear at sites of obvious pressure. Finger calluses may develop in response to using tools, playing musical instruments
such as the guitar, or using work equipment that exerts pressure at specific sites.
