How Does It Work? Applied to damp skin after washing, the Classic Natural Crystal Deodorant leaves a thin layer of natural mineral salts on your skin. These mineral salts are a natural deodorant and inhibit the formation of body odour on your skin, providing you with long lasting protection. The Salt of the Earth crystal deodorant is a 90g stick of pure Potassium Alum, a natural mineral salt that has been used as a deodorant for hundreds of years. Our crystal deodorants are unscented so they wont interfere with other fragrances like perfume or body lotion. With our Classic Crystal Deodorant, you can trust its hard-working nature to help you feel comfortable and confident — whatever life throws your way. Its gentle formula sits lightly on your skin’s surface, providing reliable protection with a lightweight feel and no sticky residue. This classic crystal deodorant has been keeping customers dry and odour-free for over 20 years. Hardworking, and comprising nothing but pure mineral salt, it remains a modern skincare classic. Perfect for men and women alike, this unscented deodorant won't suffocate your pores, but instead sits on the surface of your skin, inhibiting the growth of odour-causing bacteria. Cool dry place.
