Corns and callus refer to a buildup of tough, thickened skin that forms on high-pressure areas of the feet. Both are made up of the same deadened skin cells (keratin) and develop as a result of localised pressure or friction.
The key difference is that corns form a central core — a cone shape that pushes into deeper layers of skin. This is what creates the familiar sensation of walking on a small pebble.
Almost everyone will develop a corn or callus at some point in their life. They form as your skin's own protective response to pressure on the underlying tissue, joints or bone. The problem occurs when too much keratin builds up, which can happen due to:
There are several distinct types of corn, each requiring a slightly different approach to treatment:
The most important thing to remember about treating corns and callus is to avoid attempting removal yourself before seeing a podiatrist. Because callus is generally a symptom of an underlying pressure problem, a professional assessment is essential to identify and address the cause, not just the skin buildup.
Over-the-counter remedies such as corn paints and medicated plasters treat only the surface, not the underlying problem. Used incorrectly, they can damage the healthy surrounding skin. For patients with diabetes, poor circulation or other medical conditions, medicated corn plasters can be genuinely dangerous and should not be used without professional advice.
