Pumice stone is a porous and abrasive stone you can use to remove dead and dry skin. Its unique texture is formed when lava and water mix. The pumice stone is fantastic at exfoliation and removing skin stains and unwanted hair. You can use it on the soles of the feet, hands, knees, elbows, and any area where the skin is thick or rough. Always wet the stone and your skin before using, and follow up with a gentle moisturizer to hydrate your skin.
