Persimmon tannin soap that neutralizes age-related body odor at the source, the one thing regular soap was never built to do.





Somewhere after 40, skin starts producing a compound called nonenal, the chemical behind what people call "old person smell." It forms as natural fatty acids in your skin break down differently with age.
Unlike regular sweat, nonenal is oily, not water-soluble, so it doesn't just rinse off. It builds up on skin and clothes instead, and because your own nose adapts to it, everyone notices before you do.
Persimmon tannins bind directly to the oil itself, where regular soap simply can't reach.
Persimmon tannins target the oil-based compound that clings to skin long after regular soap rinses away.
No parabens, no sulfates, no added fragrance. Formulated to be kind to sensitive, mature skin.
Swap it in for the soap you already use. No extra step added to your routine, 60 seconds in the shower.
Kakishibu, fermented persimmon tannin, has been used in Japan for centuries for its ability to bind odor. We adapted it into a daily soap.
Fermented from Diospyros kaki and cold pressed at a trusted facility in Japan, kakishibu tannins bind directly to nonenal, the oil-based compound behind age-related body odor, neutralizing it rather than covering it up.
Contains catechins that support the tannin's odor-neutralizing effect while helping calm and soothe skin.
Nonenal doesn't build evenly across skin, it settles most in five areas. Cleanse these daily for the most noticeable results.
Give it two full cycles. If SAWUMI isn't part of your routine by day 60, we'll refund your order. No return required.
