At the height of summer, when temperatures soar and the days get longer, a good deodorant becomes essential for feeling fresh, comfortable and confident. Whether you're at work, out and about or on vacation, deodorant is an essential part of your daily routine.
But what do we really know about the deodorants we use? Are they all safe for our skin? Are natural alternatives really effective? These are the questions we answer here, to help you make an informed choice.
Sweating is natural - and even necessary!
Perspiration is an essential mechanism for regulating body temperature. It acts as a natural cooling system, activated by the body in the event of heat, physical exertion, stress or fever. Contrary to popular belief, fresh sweat is odorless. It's the bacteria on the skin that break it down, causing unpleasant odours.
Deodorant or antiperspirant: what's the difference?
The role of a deodorant is to act on and neutralize the bacteria responsible for unpleasant odors. Antiperspirants, on the other hand, go further: they temporarily block perspiration by tightening pores with aluminum salts.
This type of product is only found in conventional cosmetics. Natural cosmetics, on the other hand, respect the skin's natural functions and do not use this type of controversial component.
How does a natural deodorant work?
A good natural deodorant helps limit humidity and prevent odors, while respecting the skin. It can offer long-lasting protection if applied to clean, dry skin. Thanks to active ingredients of plant or mineral origin, it gently and effectively accompanies your day.
Here are just a few of the components frequently found on the market:
- Alum (Potassium Alum) is a natural salt that limits perspiration without blocking pores. It is found in crystal deodorants.
- Baking soda, known for its alkaline properties, effectively neutralizes odors. It is often found in solid or creamy deodorants. Beware, however, that some sensitive skins may not tolerate it well. In this case, prefer bicarbonate-free formulas.
- Essential oils, such as la lavandeTea tree and sage provide a natural antibacterial action and delicate fragrance. Citrus and peppermint provide a sensation of freshness appreciated in summer.
- Hydrolats (or floral waters) such as peppermint or witch hazel have a refreshing, purifying and slightly astringent effect, perfect for daily use.
- Natural starches (corn, potato) or diatomaceous earth absorb moisture and keep armpits dry. The latter, rich in minerals, is also well tolerated by sensitive skin.

Natural deodorants often also contain nourishing ingredients to soothe, protect and soften delicate underarm skin. And because everyone has their own preferences, they come in different forms: roll-on, solid stick, spray or cream. It's up to you to find the one that suits you best.
Choosing the right deodorant for every moment of life
Certain periods, such as pregnancy or breastfeeding, require special attention. Skin sometimes becomes more sensitive, and cosmetic choices need to be more vigilant. Avoid overpowering fragrances, aluminum, parabens and propylene glycol. Choose simple, gentle formulas that respect the skin's balance. When breast-feeding, it's also advisable to use a fragrance-free deodorant, to avoid disturbing your baby's highly-developed sense of smell.
A few tips for optimum use
Avoid applying to irritated, freshly shaved or damaged skin. Baking soda sticks are often easier to apply on slightly damp skin, while others are best used on dry skin. Creams, on the other hand, are applied with the fingers.
Bear in mind that every body is unique: a deodorant may be effective all day for one person, and require reapplication after a few hours for another. This is perfectly normal. The important thing is to find the one that suits your needs, your skin and your lifestyle.
By opting for a natural deodorant, you're choosing effective protection that respects your body and the environment. And in summer, more than ever, it's a great way to take care of yourself... naturally.
