A pumice stone is formed when hot lava mixes with water and hardens, resulting in a porous and abrasive stone perfect for sloughing away tough dry skin, and dead skin cells. Can be used on feet, elbows or knees.
To use a pumice stone, soften the skin in warm water, wet the stone, and then gently rub the stone over the area using light pressure and circular motions until you remove the dead skin. Never use a dry pumice stone on your skin. Stop immediately if your skin feels sensitive or sore.
