A pumice stone is formed when lava and water mix together. It’s a light-yet-abrasive stone used to remove dry, dead skin.

How to use : 

Wet your skin. If you’re removing hard skin on your heels, a callus, or a wart, soak the area for 5 to 10 minutes first to soften it. 

Wet the pumice and rub it against your skin using light, short strokes without causing pain. Don’t press too hard, or you might cause redness or irritation.Dry the area.

Apply moisturizer to keep your skin soft and smooth. Repeat as necessary.

Dead skin will build up in the stone's pores as you use it, so clean the stone after each use. Add a bit of mild soap to help clean the stone completely. This way, your stone will be clean and ready for action the next time you need it.

Set the pumice stone in a dry place, so it doesn't stay damp between uses. Some pumice stones come with a string attached that allows you to hang the stone to dry. If you let the stone stay wet, bacteria could grow in the pores, making it unsafe to use.

Pumice is a soft stone that will eventually wear away with continued use or become unsanitary. When it gets too small to handle easily, or the surface becomes too smooth to be effective, buy a new one.

It's best not to share your pumice stone with others.
