View productWhat is alum stone?
Alum stone is a crystallized mineral salt, known since Antiquity for its astringent properties. It comes in the form of a translucent block that simply needs to be moistened before application. Fragrance-free and alcohol-free, it leaves an invisible finish with no white marks on clothing.
The science
There are two main types of alum stones:
- Potassium alum (INCI: Potassium Alum): of mineral origin, this is the “natural” alum stone.
- Ammonium alum (INCI: Ammonium Alum): produced synthetically.
When it comes into contact with water and skin, the stone deposits a very fine mineral film with astringent properties (it tightens pores) and antibacterial properties: it limits the growth of bacteria responsible for odors.
The benefits of alum stone, a natural deodorant
| Benefit | What this changes in everyday life |
|---|---|
| Helps limit odors | Its antibacterial action slows the growth of bacteria responsible for unpleasant odors |
| Gently regulates perspiration | Its astringent effect tightens pores without completely blocking perspiration |
| No marks or fragrance | No white marks on clothing, compatible with your perfume |
| Ultra-durable and economical | One stone lasts for several months, often more than a year |
| Minimalist | A single mineral ingredient, with no unnecessary packaging |
Unlike a conventional antiperspirant, alum stone does not completely block perspiration: it is therefore perfectly suited to normal to moderate perspiration, for those who wish to let their skin breathe.
How to use alum stone?
- Moisten the stone under cold or lukewarm water.
- Glide it over clean, dry underarms with a few light back-and-forth movements.
- Let it dry for a few seconds before getting dressed.
- Rinse and dry the stone after each use, then store it in its box.
Our tips
- Apply it in the morning, just after showering, to perfectly clean skin.
- It can also be used on the soles of the feet to help limit odors, especially in summer.
- If your stone cracks, it can still be used: simply sand down the sharp edges.
The complete body care routine
Alum stone naturally fits into a simple and effective body care routine. Here are our steps, from morning to evening, with our body moisturizers.
1. Exfoliate gently, once a week
In the shower, smooth rough areas (elbows, heels) with an exfoliating cellular stone: the skin is softer and absorbs skincare products better.
2. Apply the alum stone
On clean, dry skin, glide the moistened Alum Stone over your underarms for natural freshness all day long.
3. Moisturize the body
The astringent effect of alum may slightly dry out the skin: moisturize the rest of your body with the Universal Melting Cream, with its melting texture and fast absorption.
Daily hydration

Alum Stone and Aluminum: What You Need to Know
Alum stone is an aluminum salt, so it is not “aluminum-free.” European scientific authorities (the SCCS committee) consider aluminum salts safe at the concentrations used in deodorants and antiperspirants.
If in doubt, if you have very sensitive skin, or if you are pregnant, ask your pharmacist or doctor for advice.
