Lightweight, hardened lava foam to gently slough off tough, dry and dead skin cells from the feet. Regular use of a pumice stone 2-3 times a week improves the appearance of the skin and relieves discomfort caused by corns and calluses, as the build up 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. If you notice any irritation, stop using the pumice stone immediately.
