Regular deodorants and antiperspirants kill or block the bacteria in your underarms. Our probiotic deodorant does the opposite: it adds good bacteria that compete with the bacteria that cause odour. These good bacteria already live on human skin. The goal is a lasting shift in your underarm microbiome, not a few hours of cover-up.

The spray is our clinical-strength formula with the most probiotics, made for strong body odour or odour that has not responded to other products. Think of it as a treatment. The stick is for everyday use and milder odour: it has fewer probiotics, plus prebiotics that help the good bacteria thrive. Many people start with the spray and use the stick to maintain the result.

No. It contains no aluminium salts that block your sweat glands. It targets odour, not moisture.

There are scented and unscented versions. If you are sensitive to fragrance, choose unscented. If the shop does not show the option yet, add your preference in the order notes. All our deodorants are citrus-free.

Customers have used it during pregnancy. If you have any doubts, check with your doctor or midwife first.

In our first batches of sticks, we added charcoal to check that the probiotics were spread evenly. Charcoal also helps absorb odour molecules. Later batches will no longer contain it.

No. A normal shower or bath is enough: you do not need to disinfect, and shaving makes little difference. What does help is soaking your underarms in water (bath, swimming pool or sea), which loosens odour compounds better than a shower.

Shake the can well, then spray once per underarm on clean, dry skin. Use it daily or a few times a week at first, and later once or a few times a week. The probiotics multiply on their own, so more is not better. One can lasts several months for most people.

Apply a thin layer daily or every other day. The stick works best with repetition: the longer you use it, the more your underarm microbiome improves.

Many people notice a difference within the first week. Your microbiome needs time to adjust, because bacteria also live in deeper skin layers around the hair roots, so allow a few weeks.

It differs from person to person. In our clinical trials, the good bacteria settled on the skin, and in many people they stayed. Some people apply the spray once and notice the effect for a month. Most need a top-up now and then. When your spray is finished, use nothing for a while: the best effect often shows afterwards.

Yes. The probiotics are grown in yeast extract, which can leave a light biscuit-like scent. While the new bacteria settle in, your own odour can also change for a while. This usually fades as they stabilise. If it bothers you, use less, or wash and wait a few days before you apply again.

Soap, yes: it does not kill the probiotics. Choose a liquid soap or body wash with a neutral or slightly acidic pH, rather than bar soap. Avoid regular deodorants and especially antiperspirants: they kill bacteria indiscriminately, including the probiotics. This also applies when you wear our probiotic T-shirt.

At room temperature; a fridge is not needed. Keep the stick below 40 °C, as it melts at around 50 °C. In hot weather, collect your parcel quickly: a full day in a hot letterbox can reduce the effect.

A lightweight T-shirt in organic cotton with encapsulated probiotics that are released gradually, wear after wear. Instead of killing bacteria like antibacterial clothing does, it builds a good microbiome in the fabric, so odour-causing bacteria do not get a chance. It looks and feels like a regular T-shirt.

At 30 °C with a regular enzyme-based detergent. Washing at 60 °C or higher damages the bacteria. The probiotics do not wash out quickly: after 30 wear-wash-dry cycles, about the lifespan of a T-shirt, they were still present. And because the shirt holds more good bacteria than it picks up from your skin or the washing machine, the good bacteria stay dominant.

Yes. The odour comes from bacteria and odour molecules stuck in the fabric, especially in synthetics. For regular clothes (not the probiotic T-shirt):

1. Treat the underarm area with an active oxygen or antibacterial product for 30 to 60 minutes, then wash.
2. Wash at 60 °C or higher if the fabric allows, and dry quickly, ideally outside.
3. Now and then, run an empty 90 °C wash to clean the machine.
4. Spray the probiotic spray on the underarm area of the clean, dry garment, leave it for a day and repeat a few times.

The spray ships within Europe, including the EU, the UK, Norway and Switzerland. Aerosols count as dangerous goods and cannot be flown. The stick also ships outside Europe, including to the US.

We produce in batches. A pre-order ships as soon as the new batch is ready, and you receive a tracking number when it leaves. Delivery then takes up to a week.
