You Think You’ve Tried Natural Deodorant…

…but unless your stick is baking soda-free, plastic-free, aluminum-free and actually works, you’re still in the pit-funk danger zone. Lucky for your underarms, Stank Pits is the best baking soda free deodorant for sensitive skin—and we came to play. You want to know why bicarbonate messes with your shit? Buckle up, boo.

Why Baking Soda Deodorant Can Cause Rashes (Science, Bitch)

Alright, you glorious nerds—time to dust off your chemistry class trauma. You know what pH is, right? Seven is neutral, six is where your skin likes to vibe (slightly acidic). Baking soda clocks in at a basic-ass nine. So when you slather that gritty garbage on your pits, it messes with your natural pH and basically salt-flattens the healthy bacteria you do want.

Sure, that kills odor... but it also kills your skin barrier. And when you sweat? That bicarbonate? It dissolves and dives straight into your pores like a nosy little gremlin. Cue irritation, breakouts, and full-on rash city.

A Bicarbonate-Free Deodorant That Doesn’t Quit

Enter magnesium hydroxide: the cooler, calmer base that neutralizes odor without wrecking your skin or ghosting the moment you sweat. It stays put, respects your biome, and doesn’t throw temper tantrums on your dermis.

We round it out with skin-nourishing butters, smooth vegan waxes, extra-absorbent clays and starches, odor-trapping zinc ricinoleate, and a subtle but sexy essential oil blend that says “clean, but unbothered.”

Your Pits Deserve Better—So Give It to Them

Stop flirting with inflammation. Ditch the baking soda and treat your underarms to a baking soda free deodorant that’s actually built for your body. Sensitive-skin safe. Eco-friendly. And a whole lot more effective than that greenwashed crap at the grocery store.
