Alum stone spray

Alum stone spray: the natural deodorant that changes everything

Looking for a healthier alternative to your usual deodorant? Something simple, effective, and free of weird ingredients? Then alum stone spray might just become your new morning go-to.

Long used in the form of a solid stone, it now comes in spray form — and frankly, it's much more practical!

What exactly is alum stone spray?

Behind this somewhat mysterious name lies a natural mineral that has been used for centuries for its antibacterial and astringent properties. In liquid form, it is usually found in a bottle containing purified water and potassium alum. A spritz, and you're done.

Unlike traditional deodorants, it doesn't block perspiration (which is actually a good thing), but it does prevent bacteria from growing , and therefore bad odors too. The result: you stay fresh all day long, without chemical fragrances.

Why are we adopting it more and more?

  • Because it is 100% natural and free of junk (no alcohol, no controversial aluminum, no perfume)
  • Because it is ultra soft , even on sensitive skin
  • Because it doesn't stain clothes
  • And above all: because it really works

It's also a more environmentally friendly choice: no aerosol, often recyclable bottle, and super long shelf life. In short, it's good for you and the planet.

How to use it without getting a headache?

Right after your shower, spray it under your arms (or even on your feet if needed), let it dry for a few seconds... and that's it. No need to reapply it during the day.

Some people also use it after shaving or waxing to soothe irritation. A truly multifunctional treatment.

In short: a little spray that makes a big difference

Alum stone spray is the kind of product you discover by chance... and never want to leave. It ticks all the boxes: natural, effective, simple, and kind to your skin.

So if you want to switch to a clean deodorant without losing freshness, now might be the time to give it a try . You might even wonder how you managed before!
