How do corns and calluses form?

Corns and calluses develop from repeated friction, rubbing or irritation and pressure on the skin. Corns and calluses typically form on the bony or prominent areas of feet. On the hands, they (more likely calluses) form on the areas where there is ongoing rubbing against the skin.

The hardened layers of skin of corns and calluses are actually your body’s way of protecting the underlying skin from the irritation and pressure.
