Calluses and Corns
Corns and calluses are thickened, hardened patches of skin that build up where there's repeated rubbing or pressure — the skin's way of protecting itself. Corns are small and usually form on the tops or sides of the toes, often with a hard centre that hurts when pressed. Calluses are larger and flatter, typically on the soles of the feet, and are usually not painful. Both are very common and almost always caused by footwear or friction. The key to clearing them is removing the source of pressure and gently thinning the hardened skin — never by cutting them yourself.

When to seek further care: If you have diabetes, poor circulation, or numbness in your feet, do NOT treat corns or calluses yourself — including with over-the-counter acid removers. See your pharmacist or a health-care provider first, as foot complications can become serious quickly.
