What’s the Difference Between a Deodorant, an Antiperspirant and an Anti-odorant?

Deodorants, antiperspirants and anti-odorants may be applied to the same area, but they approach body odour in three different ways.

A deodorant reduces or covers the smell.
An antiperspirant reduces the amount of sweat.
A ZINDEO anti-odorant supports the skin microbiome while targeting the bacteria associated with body odour.

That distinction matters because sweat itself has little smell. Unpleasant odour develops when particular bacteria break down components of sweat and transform them into volatile, odorous molecules.

What is a deodorant?

A deodorant is designed to reduce the perception of body odour without significantly reducing perspiration.

Depending on its formula, it may:

cover odour with fragrance,
temporarily reduce bacteria,
absorb moisture or odorous compounds,
change conditions on the surface of the skin.

Deodorants generally focus on the immediate result: making the underarms smell fresher after application. They do not necessarily aim to create a longer-term change in the underarm microbiome.

A strongly fragranced spray and a fragrance-free zinc formula can both be called deodorants, even though they work very differently.

What is an antiperspirant?

An antiperspirant is designed to reduce the amount of sweat reaching the skin.

It normally contains aluminium salts. When these salts react with moisture, they form temporary deposits in the upper part of the sweat ducts. This reduces perspiration in the treated area until the deposits are naturally removed.

Antiperspirants can be useful when the main concern is visible wetness. Their primary purpose, however, is to suppress sweat—not to work with the underarm microbiome.

Antiperspirant use is also linked to changes in the underarm bacterial community. The research is summarised in Aluminium in Deodorant and Antiperspirant: What the Science Actually Says.

Where does an anti-odorant fit in?

“Anti-odorant” is not a standardised cosmetic category. At ZINDEO, we use the term for a product that controls body odour without blocking sweat: it supports the skin microbiome while targeting the bacteria associated with body odour. The full explanation is in How ZINDEO Works.

The goal is not simply to perfume the skin or eliminate every bacterium. The goal is to make the underarm environment less favourable to the bacterial groups associated with unpleasant odour.

A ZINDEO anti-odorant:

does not use aluminium salts to block sweat,
does not rely on added perfume to cover body odour,
targets the bacteria associated with body odour,
supports the skin microbiome,
allows natural perspiration to continue.

You continue to sweat naturally while using ZINDEO; the difference is that the sweat is less likely to develop into an unpleasant smell.

Why the underarm microbiome matters

The underarm contains a relatively small but dense microbial community. Two of its dominant bacterial groups are Corynebacterium and Staphylococcus.

Different species and strains produce different enzymes and therefore different odorous compounds. Some bacteria create very little noticeable smell. Others transform components of sweat into sour, musky or sulphur-containing molecules.

This is why two people can sweat the same amount but smell completely different.

The composition of the microbiome also helps explain why body odour may:

return quickly after washing,
become stronger during puberty or hormonal changes,
differ between the left and right underarm,
change after switching products,
improve gradually rather than immediately.

A conventional deodorant mainly reduces or covers smell that has already developed. A microbiome-focused anti-odorant aims to change the conditions that allow the smell to be repeatedly created.

Microbiome-tested for 28 days

ZINDEO Anti-odorant Cream Fragrance-Free was independently tested after 28 days of daily use on ten participants.

The study found:

In 9 of 10 participants, skin microbiome diversity was higher after 28 days of daily use.

Laboratory-tested for its effect on the skin microbiome: the independent laboratory concluded that the cream supports the skin's commensal microbiota.

Microbial diversity alone is not a universal measure of skin health. The composition of the bacterial community also matters.

Clinically tested odour control

A separate split-underarm study on people with strong body odour compared the Fragrance-Free ZINDEO Anti-odorant Cream with an untreated underarm (full results on our Clinical Testing page).

11 of 12 people had less body odour 24 and 48 hours after the last application. The reduction was still statistically significant 72 hours after the last application (after 6 days of use).

The study measured body odour, not sweat reduction. ZINDEO contains no antiperspirant aluminium salts, so it does not block natural perspiration.

If you sweat excessively, talk to a doctor: ZINDEO does not reduce sweating, it controls body odour.

Is there a natural antiperspirant?

An antiperspirant reduces sweating, usually with aluminium salts. Products sold as natural antiperspirants, such as alum stones (potassium alum), are aluminium salts too, so they are not aluminium-free. If you want to stop using aluminium, you are dealing with odour rather than sweat, and that is what an anti-odorant such as ZINDEO is for. You can compare the options in our aluminium-free deodorant collection.

Which product should you choose?

Choose an antiperspirant if your main priority is reducing sweat and visible wet patches.

Choose a conventional deodorant if you mainly want short-term freshness or fragrance.

Choose a ZINDEO anti-odorant if you want to control body odour by working with the underarm microbiome while allowing natural perspiration to continue.

Not just another aluminium-free deodorant

ZINDEO is a natural deodorant without aluminium or baking soda, but it is not simply another aluminium-free deodorant: it is a microbiome anti-odorant designed for longer-term odour control. In RESET SET START and RESET SET MAX, the Anti-odorant Cream is the core step.

RESET SET MAX — SALSOAP® + Roll-on + Cream. The complete routine for stronger body odour or switching from a conventional deodorant or antiperspirant.
