Calluses and corns form when there is too much friction and pressure put on your feet, usually from poorly fitting shoes or not wearing socks. These areas are very dry and moisturizing the area can help treat your corns and calluses.
If you soak your feet in warm, soapy water once or twice a day, it can help soften the corns and calluses. While the skin is soft, you can use a rough cloth or a pumice stone to remove the dead layers of thickened skin.
Putting moisturizing lotion on your feet before putting shoes or socks on can help reduce friction and cut down on the growth of new corns and calluses.
If you wear shoes and socks that are fit well and cut down on pressure and friction, your corns and calluses will lessen, according to the Mayo Clinic. Try to use shoes that are well-cushioned and aren't too tight.
The best socks to prevent corns and calluses are a polyester-cotton blend (more so than cotton) because they absorb sweat better, preventing the creation of friction.
There are numerous over-the-counter remedies you can purchase to use at home to reduce your corns and calluses. Most of these remedies are small pads that you apply to your feet that protect the usual places where calluses and corns are likely to develop.
There are also liquid drops available to reduce corns and calluses, but you should use caution when applying them. These drops often contain salicylic acid, also used to treat plantars warts.
If not used properly, this acid can also eat through healthy skin cells, causing irritation and even an infection in some people. If you have diabetes, using salicylic acid is potentially very dangerous.
