Corn:
Information for adults

Corns are thickenings of the skin composed of keratin that are typically found on the toes caused by repeated friction or pressure to the area. The base of the corn is seen on the surface of the skin while the top points inward, causing discomfort.

Corns are classified as either hard or soft, depending upon their location and appearance. Hard corns typically affect the tops of the toes and are composed of a dense core that presses on sensory nerves, causing extreme pain. Soft corns occur between the toes and are whiter and softer in appearance due to the continuous softening by sweat.
