Why does my corn or callus have a hard yellow lump in the centre?
A hard yellow lump in the centre of a corn or callus is typically caused by the thickening of skin in response to repeated friction or pressure. This hardened area forms as a protective mechanism, leading to the development of a core that can appear yellow. The colour and firmness are due to the accumulation of dead skin cells in the affected area.
Key points:
- Corns and calluses form from friction or pressure on the skin.
- The hard centre is a build-up of thickened skin.
- Yellow colouration can result from dead skin cells.
- These formations are protective responses of the skin.
