These porous volcanic rocks are formed when hot lava mixes with water and hardens. They are highly effective in eliminating dry, dead skin from the soles of feet. To use, simply soak your feet in warm water for approximately 5 minutes to soften the tough skin. Then, wet the pumice stone and gently rub it in a circular motion with light pressure on your sole for about 2 minutes. Finally, rinse your feet thoroughly. For an added touch of care, apply our intense moisture bar to nourish and pamper your newly smooth skin.
