Calluses form when your skin is subjected to excessive pressure or friction. This causes the buildup of dead skin cells and often feels uncomfortable or painful. A Tweezerman Callus Shaver gently shaves off the callus from your skin to make it smooth. The blade on a Tweezerman Callus Shaver will need to be replaced when it becomes dull -- this could occur in one to three months, or more, depending on how often the shaver is used. Replace the blade properly to help your callus shaver work effectively.
