Sensitive Skin Finally Has a Deodorant That Works...
and Loves You Back

No more angry red bumps. No more stinging sprays. No more choosing between pain or pit-stains.


FatCo’s Stank Deodorant is powered by nature’s original skin healer — grass-fed tallow — and it’s changing how sensitive pits stay fresh.

Why Regular Deodorant Makes Skin Freak Out

You’re not imagining it. That burn, those breakouts, the discomfort that lingers long after a shower...

Most deodorants — even the ones labeled “natural” — are packed with lab-made chemicals, synthetic scents, and pore-clogging aluminum. These disrupt your skin’s natural defense system, inflaming sensitive underarms and causing irritation, rash, or worse.

Ancient tallow use or modern jar

The Real Fix Has Been Around for Over 5,000 Years

Our ancestors used tallow for a reason. It mimics your body’s own natural sebum — the protective layer of oils that calms, hydrates, and guards your skin.

FatCo’s deodorant is made from grass-fed beef tallow, infused with essential oils, and completely free of anything your body can’t recognize. It’s deodorant that speaks your skin’s language — no translator (or toxins) needed.
