In the world of natural beauty, few ingredients have received as much praise — or provoked as much controversy — as baking soda for underarms. Marketed as an affordable, toxin-free alternative to traditional deodorants, it has become a household staple for those seeking cleaner, greener personal care routines.
But here’s the truth: sometimes, what’s natural isn’t always safe — and baking soda may be one of the most misunderstood culprits.

The Rise of DIY Deodorant Culture
In recent years, the move toward clean beauty has inspired millions to ditch conventional deodorants in favor of kitchen-made solutions. Among these, baking soda for underarms quickly gained cult status, praised for its ability to neutralize odor on contact.
Praised for its odor-neutralizing properties, baking soda for underarms became a go-to DIY deodorant alternative. It’s affordable, accessible, and seems effective — at least at first. For many, it felt like the holy grail of natural odor control.
- Cheap
- Readily available
- Effective (at least temporarily)
So, what could possibly go wrong?
When Alkalinity Disrupts the Skin
The issue lies in the science.
Baking soda has a pH of approximately 9, while your skin’s natural pH hovers around 5.5 — slightly acidic, and perfectly balanced to support its protective barrier. When high-alkaline substances like baking soda are applied repeatedly to delicate underarm skin, they can cause:
- Disruption of the skin microbiome
- Itching, burning, or inflammation
- Underarm rashes and peeling
- Hyperpigmentation (dark patches)
- Increased sensitivity or even chronic irritation
Why the Underarm Microbiome Matters
Your underarms are home to a unique microbiome — a delicate balance of bacteria that play a vital role in body odor, skin health, and immune function. Harsh DIY products like baking soda don’t just eliminate odor; they disrupt this natural ecosystem, often leading to more intense odor over time, not less.
Proper care means respecting the skin’s natural environment — not battling it.
Your underarms are home to a complex microbiome that manages sweat, odor, and skin balance. Applying highly alkaline ingredients like baking soda can strip this ecosystem and lead to an imbalance of bacteria — often making body odor worse in the long run.
“Natural” Doesn’t Always Mean Gentle
Countless testimonials echo this sentiment. What starts as a harmless kitchen experiment can quickly result in damaged skin and persistent discomfort. That’s why more skincare-conscious users are now seeking advanced, science-backed alternatives.
Real Experiences, Real Damage
Across forums, beauty blogs, and dermatology offices, the stories repeat themselves:
“I was trying to go natural, but my underarms turned raw after a week.”
“The baking soda helped with odor — but I ended up with painful bumps and discoloration.”
“I thought I was doing the right thing. My skin said otherwise.”
While these stories differ in detail, they all speak to one core truth: underarms require thoughtful, pH-balanced care.
