How Magnesium Fights Odor: The Science Behind Natural Deodorant

How Magnesium Fights Odor: The Science Behind Natural Deodorant

Let’s face it, no one wants to smell bad. But if you’ve got sensitive skin, finding a deodorant that actually works without irritating your underarms can feel like an endless search.

Enter: magnesium.

At MAGS Skin, we use magnesium hydroxide as the star ingredient in our deodorant. Not aluminum, not baking soda, and definitely not artificial fragrance. But how does it actually fight odor? And why is it such a game-changer for sensitive skin?

Let’s break it down.

What Really Causes Body Odor?

Contrary to popular belief, sweat itself doesn’t smell. In fact, sweat is mostly made of water, salts, and trace minerals.

The real culprit behind body odor?
👉 Bacteria.

Specifically, odor-causing bacteria that live on your skin, especially in warm, moist places like your armpits, feed on the proteins in your sweat. As they break it down, they release smelly compounds that cause that all-too-familiar funk.

How Deodorants Work (The Right Way)

A good deodorant should:

  1. Let your body sweat naturally
  2. Stop odor before it starts
  3. Be gentle on your skin

Magnesium deodorant checks all three.

Instead of blocking your sweat glands (like antiperspirants that use aluminum), magnesium deodorant works by changing the pH on your skin, making it less hospitable for odor-causing bacteria to thrive.

No bacteria = no stink.

Why Magnesium Is a Better Option Than Baking Soda

Many natural deodorants use baking soda to fight odor, but here’s the problem:

🔺 Baking soda is highly alkaline, which can disrupt your skin’s natural pH
🔺 It often causes redness, itching, or rashes, especially for sensitive skin types
🔺 Over time, it can weaken your skin barrier, making irritation worse

Magnesium, on the other hand:

✅ Has natural antibacterial properties
✅ Supports your skin’s natural balance
✅ Is non-irritating, even for people with eczema or psoriasis

That’s why magnesium vs. baking soda is a no-brainer, especially if your pits have been through enough.

Final Thoughts

Magnesium doesn’t just fight odor, it does it without a fight with your skin. And that’s the difference.

If you’ve been burned (literally or figuratively) by baking soda deodorants or felt dry and itchy from traditional sticks, switching to a magnesium deodorant might be the best thing you do for your pits.
