Why Magnesium Hydroxide is the Secret to a Gentle, Effective Deodorant

If your skin gets angry every time you try a new deodorant, you’re not alone. 

Most formulas either block your sweat (which your body doesn’t love) or use harsh ingredients that throw your skin out of balance.

That’s why MAGS Skin is powered by magnesium hydroxide, a mineral that keeps odor in check without the irritation.

What is Magnesium Hydroxide?

Magnesium hydroxide is a naturally derived compound often used to calm the stomach (yep, it’s the same base as Milk of Magnesia).

But when applied to the skin, it works in a different way: it helps neutralize the bacteria that cause odor while keeping your skin’s pH balanced.

Unlike baking soda (which is super alkaline), magnesium is gentle, non-irritating, and supports your skin barrier. It gets the job done without the side effects.

Why We Use Magnesium Instead of Baking Soda
Baking soda may seem natural, but for many people it leads to:

  • Burning or stinging
  • Underarm rashes
  • Peeling or flaking skin

That’s because it throws off your skin’s natural acidity. Magnesium hydroxide, on the other hand:

  • Keeps odor-causing bacteria under control
  • Doesn’t clog pores or trap sweat
  • Respects your skin’s pH
  • Actually feels good to use
Comparison table: Magnesium hydroxide—gentle, neutralizes odor, supports skin pH; Baking soda—can burn, disrupt pH


Why Magnesium Works So Well for Sensitive Skin

We didn’t choose magnesium by accident. We picked it because:

  • It’s non-toxic and naturally antibacterial
  • It won’t block sweat glands
  • It’s safe for sensitive skin, even after shaving
  • It calms irritation instead of causing it

In short, it’s the kind of ingredient your skin doesn’t have to recover from.

It's the reason MAGS Skin works so well without the side effects.

No sting. No junk. No irritation.
