This is an aluminum free crystal deodorant comprised of the earth’s mineral crystal combined with natural botanicals. Aluminum in antiperspirant prevents you from sweating and may pose danger to your health. Most people think that they need to block the sweat to prevent odor however all you need is a neutralizer. Effectively works with the safe potassium alum molecules which are large size particles and therefore do not absorb like the aluminum molecules. It neutralizes strong body odor without blocking your sweat glands. Has a pleasant natural bay rum scent without phthalates. Long lasting throughout the entire day.
