A New Approach to Replace Odor-Causing Bacteria with Non-Odor Bacteria.

Swap™ is a revolutionary new deodorant utilizing Silicon Valley biotechnology to replace odor-causing bacteria with non-odor-causing microbes.

Won't wash off with showers or sweat.
Lasts for more than 7 days.

With just one application, it balances bacteria and keeps odor under control for more than 7 days (currently in clinical trials). Whether you're sweating or showering, the effect lasts, offering care for underarm odor without the need for surgery or laser treatments.

How Swap Works

Breakthrough in Body Odor Control:
Successfully Altered Bacteria with Biotechnology

The odor associated with underarm odor occurs when skin bacteria break down and metabolize secretions from the apocrine glands. Swap has achieved the world's first "genetic modification of odor-causing bacteria" (patent pending). We've developed "Taxa Probiotics™," an odorless bacterium that doesn't produce smell even when you sweat.

When you apply Swap, which contains "Taxa Probiotics™," to your underarms, the odor-causing bacteria are replaced with odorless bacteria for a long-lasting effect, fundamentally curbing the development of the odor. Just one application can offer lasting effects for over 7 days (clinical trials underway).
