Corns / Callus

Corns / Callus

What are corns and callus?

Corns and callus are layers of hardened skin that build up over time.

New skin cells develop deep within the skin and slowly make their way up to the surface, where they are shed naturally. This usually takes about 3-4 weeks.
If your feet rub in your shoes, through pressure or friction, these cells can compact into layers of hardened skin. This can occur where the joints are protruding, if you walk in a certain way or if your footwear is badly fitted.

  • Corns are small circular areas of hardened skin, and there are five different types. The two most popular types are hard and soft corns. Hard corns occur on the top or sides of the feet and can indicate how well your feet and toes are working. Soft corns are a build-up of skin between the toes. Both can be very painful.
  • Calluses have no clearly defined boundaries and tend to be larger than corns. They can occur on any part of the foot

Treatment & Prevention

Regular filing with a foot file or pumice stone and moisturising. If the skin has become very thick and painful, visit a podiatrist who can reduce it professionally. Other treatments can include pressure relief with simple insoles or orthotics and footwear advice.

Corns can be deep. Consult a podiatrist for advice and removal of a corn. If you are diabetic or have poor circulation, do not use corn plasters or products containing acid which burns the healthy skin around the corn. A podiatrist will be able to prescribe and make protective pads or orthotics and simple insoles to relieve painful corns.
