SCHOLL CORN AND CALLUS REMOVAL is specifically made to safely and effectively remove painful corns and calluses on feet. It comes in a maximum strength medicated liquid (Salicylic Acid) for an effective work as it relieves painful shoe pressure and friction to provide immediate and all-day pain relief. SCHOLL CORN AND CALLUS REMOVAL works by increasing the amount of moisture in the skin, and dissolving the substance that causes the skin cells to stick together. This makes it easier to shed the skin cells.
