Corns, like calluses, are a thickening and hardening of the skin in reaction to continual pressure or friction. Corns typically appear on or around the toes, and some, called "seed corns," may form on the sole of the foot. Though they are a defensive measure against blistering and usually pose no medical danger, corns are a cosmetic concern and can cause considerable discomfort or pain. Corns generally go away once the source of pressure or friction is removed, but using a pumice stone to remove corns provides a quicker remedy.
Clean your pumice stone thoroughly with warm water and an antibacterial agent. If it's not sterile, there is risk of infection with use.
Bathe or shower prior to using a pumice stone. Alternatively, fill the bathtub or a bucket with enough warm, soapy water to fully submerge the foot with the corn. Opt for a liquid soap with moisturizing ingredients. This helps soften the tough skin on the corn in preparation for using the pumice stone.
Wet the pumice stone and rub it back and forth over the corn, applying light pressure.
Stop rubbing the corn after a minute or two. Rinse your foot off quickly to remove flakes of skin and small particles from the pumice stone. Continue rubbing the corn again, repeating this process until the corn is almost fully worn down. Be sure to stop before you get down to healthy, normal skin.
Wash your foot again with warm water and soap when finished. This will clean off any remaining skin and small pieces of pumice stone and help guard against infection in the event of any breaks in the skin.
Rub a moisturizing salicylic acid cream or lotion on the foot to help keep the skin hydrated and soft, and to help prevent the development of new corns.
