As skin changes with age, so can body odor, largely due to a compound called Nonenal, first identified by Japanese researchers in the early 2000s. Persimmon tannin has been studied for its ability to help neutralize it. Here's the plain language version.
Nonenal, explained
In the early 2000s, Japanese researchers identified a compound called 2-nonenal as a major contributor to a distinct shift in body odor that tends to appear starting in a person's 40s, linked to changes in skin lipid oxidation. It's a real, well documented phenomenon, not a marketing invention, and not a personal failing.
Persimmon tannin
Known in Japan as kakishibu, persimmon tannin has a long history as a natural preservative and deodorizing agent, and has more recently been studied for its ability to adsorb and help neutralize nonenal specifically. We use Diospyros kaki (Japanese persimmon) fruit extract as the core active in an otherwise simple, unscented bar.
Unscented by design
No fragrance layered on top to mask anything. The bar is formulated to help address a cause, not cover a symptom, which is also why you won't find added fragrance anywhere on our ingredient list.
We keep our claims here modest and sourced: persimmon tannin is studied for helping to neutralize nonenal. We don't claim it eliminates or cures anything. This page is for context, not a medical or dermatological guarantee.
