Corns are essentially calluses that appear on toes, notes the Cleveland Clinic. Due to continuous irritation, skin on the toe begins to thicken and harden. This response to chronic friction or pressure is a defensive mechanism with which the skin protects against blistering or ulcers. Left unchecked, corns become painful and can make walking difficult. While you can remove corns at home, those with diabetes or other conditions causing inhibited circulation should seek treatment advice from their doctor.

Apply an astringent foot powder and wear polyester-cotton blend socks to reduce perspiration, if it is a problem. Irritation from sweat and friction contributes to corns. Apply an astringent or over-the-counter foot powder daily, suggests the Cleveland Clinic. Cornstarch or talcum powder are other effective options, according to Suzanne M. Levine, D.P.M., a podiatrist at Mount Sinai Hospital in "The Doctors Book of Home Remedies." Wear socks made from a blend of polyester and cotton, as they wick moisture away from the skin.
Replace shoes that are too tight, particularly if they're tight in the tips around the toes. This is a leading cause of corns, notes the Cleveland Clinic. Without eliminating the source of friction or pressure that led to the corn, it will be difficult to remove and will likely recur.
Wear a corn pad around the corn before removal. These doughnut-shaped linings protect the corn from further irritation and prevent growth. Opt for one containing salicylic acid, which helps remove the dead skin on the corn and begins to soften the growth, the Nemours Foundation explains.
Make a foot bath with warm water and a small amount of liquid soap. Soak the foot with the corn for about 10 minutes.
Wet a pumice stone. Rub it lightly across the corn, using a side-to-side motion. Rinse the stone and your foot periodically to remove small bits of flaking pumice. Continue until the corn is sanded down almost to the surface of your skin. Be careful not to reach the surface of healthy skin.
Continue wearing a non-medicated corn pad around the treated area for a day or two to prevent irritation, blisters or recurrence.
