Choosing the right deodorant goes far beyond the scent. Skin type, how much you sweat and the product's ingredients are key to finding the one that best suits your needs. We explain everything.
How deodorant works
Sweat itself has no smell. Body odour appears when this natural substance comes into contact with bacteria on the skin. That is why the key to a good deodorant lies in its antibacterial action, which slows the growth of these micro-organisms without causing irritation or other negative effects on the skin.
It is important to distinguish between two types of product:
- Deodorant: removes or neutralises body odour, but does not reduce sweating
- Antiperspirant: as well as fighting odour, it reduces the amount of sweat thanks to aluminium salts that act on the sweat glands
Types of deodorant for women
Spray deodorant
The most popular format thanks to its speed and convenience. It is applied from a distance, dries in seconds and leaves no residue. Ideal for normal or combination skin. Look for formulas that state they don't stain clothes for extra peace of mind.
Roll-on deodorant
Applies the product directly onto the skin, ensuring more precise coverage. Especially recommended for sensitive skin, as it usually contains fewer additives and many formulas include soothing actives that reduce irritation after shaving.
Stick deodorant
A solid format that offers very good protection and a low risk of stains on clothes. It is the most common format for paraben-free versions and natural mineral-based deodorants.
Cream deodorant
Less common but very effective: it is applied with the fingers and lets you control exactly how much you use. Its formula is usually more concentrated, so a very small amount is enough.
Natural or organic deodorant
Formulated without aluminium salts, parabens or synthetic fragrances. Ideal for very sensitive or reactive skin. Their effect usually lasts a little less, but they are an excellent option for a more natural hygiene routine.
Ingredients to look out for
| Ingredient | Function | Look for or avoid? |
|---|---|---|
| Aluminium salts | Reduce sweating (antiperspirants only) | Look for them if you sweat a lot; avoid on very sensitive skin |
| Aloe vera or panthenol | Soothe and moisturise the skin | Always look for them, especially for sensitive skin |
| Sodium bicarbonate | Neutralises odour (natural formulas) | Look for it in natural deodorants; may irritate very reactive skin |
| Parabens and colourings | Preservatives and synthetic fragrances | Avoid if you have sensitive or reactive skin |
| Alcohol | Helps the product dry | Avoid on dry or easily irritated skin |
Tips for choosing your ideal deodorant
- Sensitive skin: choose a roll-on or stick without parabens or alcohol and with a hypoallergenic formula
- Heavy sweating: an antiperspirant with aluminium salts gives stronger protection for longer
- During sport: spray or roll-on formats with a 48h effect are the most recommended
- If you prefer natural: deodorants with a mineral or organic formula are the most suitable
Frequently asked questions
Is deodorant better with or without aluminium?
It depends on your needs. If you also want to reduce sweating, an antiperspirant with aluminium salts can be more effective. If you prefer to respect the natural sweating process and only remove odour, an aluminium-free deodorant is the most suitable option.
How long does a deodorant protect you?
Most deodorants on the market offer protection for 24 to 48 hours, although this can vary depending on skin type and level of physical activity. On very hot days or when exercising, you may need to reapply.
Can deodorant stain clothes?
Yellow stains on clothes are usually caused by aluminium salts (found in antiperspirants) combining with sweat. To avoid them, let the deodorant dry fully before getting dressed and consider stick or spray formats designed not to stain.
