Feature
One swipe. One week. A new kind of underarm care that replaces the bacteria itself.
Replace the bacteria
that cause body odor
with odorless bacteria.
Swap™ is a new deodorant powered by Silicon Valley biotechnology that replaces the bacteria causing underarm odor with odorless bacteria.
One swipe lasts a week,
won't wash off with shower or sweat.
Just one application is all it takes. Swap rebalances your underarm microbiome. A new kind of odor care that stays put through sweat and showers.
Mechanism
How Swap Works
Mechanism
How Swap Works
Biotechnology that rewrites the genetics of odor-causing bacteria
Underarm odor occurs when bacteria on the skin break down secretions from the apocrine glands. Swap has succeeded in genetically modifying these odor-causing bacteria, creating Taxa Probiotics™ — odorless bacteria that don't produce odor even when you sweat.
Applying Swap, which contains Taxa Probiotics™, to your underarms replaces the odor-causing bacteria with odorless ones for the long term, stopping odor at the source.

What our early testers are saying
After trying Swap, I can't go back to any other deodorant.
Even after a full week, I didn't notice any odor at the end of the day. Before, I always had a faint smell even with deodorant. Once I started a monthly subscription, I honestly don't think I could go back to a regular deodorant.
Elizabeth
Even after two days, there was no odor.
Two days in, I realized I didn't need to put on deodorant at all. I almost reached for it out of habit, but since there was no odor I just stopped.
Anna
I don't need daily deodorant anymore.
Using this product was the first time I asked myself, "Do I really need deodorant every day?" My answer was "no."
Matthew
Not having to use deodorant every day is a huge convenience.
Since trying Swap, I've stopped worrying about applying deodorant every single day.

Swapを使ったら、もう他のデオドラントには戻れない。
1週間経っても、1日の終わりにニオイを感じることはありませんでした。以前はデオドラントを使っていても多少のニオイがしていたのに。この製品を毎月定期購入していたら、おそらく従来のデオドラントには戻れないでしょう。
Elizabeth
2日たってもニオイがしなかったんです。
2日経ったときに、デオドラントを塗る必要がないことに気づきました。習慣で塗りそうになりましたが、ニオイがしなかったので、そのままやめました。
Anna
毎日のデオドラントはもう必要ない。
この製品を使って初めて『本当に毎日デオドラントが必要なのか？』と考えました。その答えは『ノー』でした。
Matthew
毎日デオドラントを使わなくていいのが、とても便利。
Swapを試してから、毎日デオドラントを使うことを気にしなくてよくなりました。
