What is a callus and how does it differ from a corn?

A callus is a thickened area of skin that forms in response to repeated friction or pressure, often found on the hands or feet. In contrast, a corn is a smaller, more concentrated area of thickened skin that typically develops on the toes due to similar friction but often has a hard centre. Both are protective responses of the skin but differ in size, location, and shape.

Key points:

  • Calluses are larger and flatter than corns.
  • Corns are smaller and usually have a hard centre.
  • Both develop due to friction or pressure on the skin.
  • Calluses often appear on hands and feet, while corns are mainly found on toes.
