Corns are areas of thickened skin caused by repeated friction or pressure. To treat them safely at home, you can soak your feet in warm water to soften the skin, then gently use a pumice stone to file down the corn. Over-the-counter treatments containing salicylic acid (such as medicated pads or liquids) are highly effective in dissolving the hardened skin. Using protective, doughnut-shaped adhesive pads can also relieve pressure. Most importantly, ensure your shoes fit well with plenty of room for your toes. If you have diabetes, poor circulation, or if the corn becomes very painful or inflamed, please consult a doctor instead of self-treating.
