Marvelous magnesium! Magnesium is a natural alternative to ingredients that are not only nasty for the environment, they don't do your skin any favours either. Magnesium is a super-power in deodorants because it neutralises your skin's pH, creating the kind of environment that's too high for odour-causing bacteria to thrive. The MiaBelle deodorants also contain Tea Tree Oil which contains robust antimicrobial, antiseptic, antibacterial, antifungal and antiviral properties - everything you need in a deodorant!
