Medicare Pumice Stone with brush is designed to gently reduce and smooth roughened skin. The pumice buffs off tough, dry skin and dead skin cells from the feet, while the soft bristled brush gently cleanses your feet and toe nails and can be used to gently brush away any loose dead skin cells. The pumice stone can also be used gently on hardened skin at the elbows and knees. Regular use of a pumice stone improves the appearance of the skin and relieves discomfort caused by calluses. It's always a good idea to apply some moisturizing lotion to your feet, following exfoliation with a foot file or pumice stone. This will help keep the skin pliable and prevent cracking skin and fissures.
