Corns are hard, thickened areas of skin which occurs due to rubbing, friction or pressure on the skin. Corns are generally form on the top and sides of the toes. A hard corn is a small patch of thick dead skin with a small plugin skin in the centre. A soft corn has a much thinner surface, appears whitish and usually occurs between the toes. Seed corn are clusters of tiny corns that can be very tender and occur on the bottom of the feet.

Calluses are hard and rough areas of skin that develop on hands, feet or anywhere there is repeated friction.

Most corns gradually disappear when the friction or pressure stops. Sometimes salicylic paints are used but these are not suitable for everyone
Co2 Laser evaporates the dead tissue by burning it off. After few days skin heals and the thicker tissue is gone.
