Regular use of a pumice stone 2-3 times a week helps improve the appearance of the skin and relieves discomfort caused by corns and calluses, as the buildup on your feet compromises the skin’s ability to function optimally. It is a gradual process, not an all-in-one-day event. Use a pumice stone by gently applying light pressure and rub in the same direction to remove the outermost layer of dead skin cells. Use brush to clear skin. Be sure to finish by hydrating skin. If you notice any irritation, stop using the pumice stone immediately.
