How to Switch from Antiperspirant to Natural Deodorant Without Stress

Switching from an antiperspirant to an aluminium-free product changes two things: you begin sweating normally again, and your underarm microbiome is exposed to a different environment.

This is not a “detox”. Your underarms are not removing stored toxins. The product has simply stopped reducing perspiration, while the bacterial community responsible for body odour may respond to the new routine.

Understanding this difference makes the transition much easier.

What changes when you stop using an antiperspirant?

Antiperspirants use aluminium salts to form temporary deposits in the upper part of the sweat ducts. This reduces the amount of sweat reaching the skin.

When you stop using one, these deposits gradually disappear and normal perspiration returns. You may therefore notice wetter underarms, especially during hot weather, exercise or stress.

This does not mean that the new product is making you sweat more. It means that your previous product was suppressing some of the sweat.

An aluminium-free deodorant or anti-odorant controls odour but does not prevent wetness. Here is how deodorants, antiperspirants and anti-odorants differ.

What happens to the underarm microbiome?

Body odour is created when bacteria break down components of sweat into volatile, odorous molecules.

Antiperspirants, deodorants, washing habits and skincare products can all influence the bacterial community living in the underarms. When you stop one product and begin another, the environment on the skin changes.

The smell may improve quickly, fluctuate or take longer to stabilise. There is no universal one- or two-week transition period that applies to everyone.

Your starting microbiome, previous products, hormones, stress, clothing and the intensity of the original body odour can all affect the process.

What Research Shows About Stopping Antiperspirants

In a 2016 study published in PeerJ, Urban and colleagues examined how deodorant and antiperspirant use affected the underarm microbiome of 17 participants over eight days.

When participants stopped using these products, the number of culturable bacteria increased. When antiperspirants were applied during the final two days of the experiment, bacterial numbers dropped dramatically.

The researchers also found differences in bacterial species richness and community composition between people with different long-term product habits.

These findings demonstrate that underarm products can influence not only perspiration and odour management, but also the bacterial communities living on the skin.

Importantly, the study did not establish a universal transition period, prove a deodorant "detox", or test how long body odour takes to improve after switching products.

Natural deodorant and ZINDEO are not the same thing

Natural deodorants control odour in different ways. Some use fragrance to cover the smell, while others rely on baking soda or antimicrobial ingredients.

ZINDEO is a microbiome-focused anti-odorant. It supports the skin microbiome while targeting the bacteria associated with body odour, rather than merely masking odour after it appears.

The ZINDEO routine does not contain antiperspirant aluminium salts or baking soda. Natural perspiration continues while the products target the microbial process responsible for unpleasant odour.

Begin with clean, dry skin

Old antiperspirant, deodorant, oils and dead skin can accumulate in the underarm area. Proper cleansing prepares the skin for the new routine.

Use SALSOAP® during your evening shower:

Wet the underarms with warm water.
Create a creamy lather.
Leave the foam on the skin for approximately 30 seconds.
Rinse thoroughly.
Dry the underarms completely.

SALSOAP® prepares the skin but does not replace an anti-odorant. It should be followed by the Roll-on, the Cream or both, depending on the set you choose.

Start the routine in the evening

After SALSOAP®, the Roll-on or the Cream is applied in the evening, when the skin is clean and sweating is usually lower. In RESET SET MAX, the Cream is applied in the morning.

Evening application also gives the product time to absorb before you put on daytime clothing. This reduces the risk of temporary white traces on dark fabrics.

Apply a very small amount in a thin, almost invisible layer. Applying more product does not automatically improve the result.

During the first three months, follow the routine consistently every day. This is the ZINDEO RESET, our recommended introduction, and it makes it possible to evaluate whether the routine is working for you.

Choose the right ZINDEO set

DAILY SET: a simple everyday maintenance routine

The DAILY SET combines SALSOAP® with the Fragrance-Free Anti-odorant Roll-on as a simple everyday maintenance routine. It is not intended as a set for switching from an antiperspirant.

Choose it if:

your body odour is milder,
you want a quick and simple application,
you prefer a roll-on,
you have unshaved underarms.

The Roll-on contains alcohol. Do not apply it immediately after shaving.

RESET SET START: soap and cream

RESET SET START combines SALSOAP® with the Anti-odorant Cream.

Choose it if:

you prefer a cream,
you prefer the Fragrance-Free cream, which contains no alcohol,
you want the cream that was clinically tested in its Fragrance-Free variant,
your body odour is milder and you want a two-step routine without the Roll-on.

Only a very small amount of cream is required.

RESET SET MAX: the complete routine

RESET SET MAX combines SALSOAP®, the Roll-on and the Anti-odorant Cream, the core step of the routine.

Choose it if:

body odour is strong or persistent,
ordinary deodorants repeatedly fail,
the smell returns quickly after washing,
you have experienced the problem for a long time,
you want to begin with the complete ZINDEO routine.

RESET SET MAX is the recommended starting point when you are switching from an antiperspirant or when body odour is more pronounced.

What should you expect during the first three months?

Some people notice a reduction in odour within days. Others need several weeks of consistent use. This is customer experience, not a clinical result.

During the first three months:

continue applying the selected anti-odorant daily,
use it on clean and completely dry skin,
do not judge its performance by wetness,
avoid layering it over old product or sweat,
contact ZINDEO if the odour remains unchanged or becomes stronger.

The purpose of the three-month routine is not to wait passively for a “detox” to finish. It is to use the products consistently and evaluate odour control. The three-month period is a ZINDEO routine recommendation, not a scientifically established microbiome adaptation period.

What happens after three months?

Once body odour is consistently under control, many people gradually reduce how often they use it, according to their needs.

The final frequency is individual: use the lowest frequency that continues to control your body odour reliably.

If the smell begins to return, temporarily increase the frequency again.

You will still sweat

ZINDEO does not promise dry underarms. It is not an antiperspirant.

The Fragrance-Free Anti-odorant Cream was clinically tested on people with strong body odour, with one underarm treated and the other left untreated. 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 odour control, not sweat reduction.
