Pumice stones are lightweight, porous volcanic rocks formed when lava cools quickly and traps gas bubbles. They are commonly used in beauty and personal care for exfoliating skin, particularly on feet, to remove dead skin cells and calluses. In addition to their cosmetic uses, pumice stones are also utilized in construction and landscaping. Their unique texture makes them effective for improving soil aeration and drainage. Furthermore, pumice is often ground into powder for use in various industrial applications, including as an abrasive in cleaning products.
