Magnesium-based deodorants gently adjust the pH of your armpit to kill odor-causing bacteria without causing the unwanted redness, rash, or skin irritation commonly linked to natural deodorants containing sodium bicarbonate. Unlike bicarb, magnesium hydroxide is less soluble in water, dissolving more slowly in sweat. This results in a balanced and gentle approach to inhibiting sweat-loving bacteria and controlling unwanted body odor only when needed. If you’ve tried a baking soda deodorant, developed a rash, or noticed it’s like rubbing fine sandpaper on your pits, a premium Natural deodorant with magnesium may be a better option.
