A callus remover is a tool or product designed to eliminate thickened skin, known as calluses, that often forms on the feet and hands. These calluses develop due to repeated friction or pressure, and using a callus remover can help restore smoother skin. There are various types of callus removers, including pumice stones, foot files, and chemical solutions. Each type works differently; for example, pumice stones physically scrub away dead skin, while chemical removers dissolve the callus. Regular use can improve comfort and foot health, making it easier to wear shoes and engage in daily activities.
