Alum stone has been used for centuries for many purposes due to its astringent properties. It is particularly effective as a natural deodorant as the mineral salts in alum stone prevent the formation of odour-causing bacteria. Either moisten the stone with water or apply to wet skin and rub to give effective long lasting protection. Alum stone can also be used to relieve razor burn and to help heal minor cuts. This polished potassium alum stone is 100% pure, hypoallergenic and is suitable for even the most sensitive of skin. A fantastic natural and safe product which can be used by the whole family!
