There's something that happens with age.
The body produces more of a naturally occurring compound
called nonenal a process that accelerates around the
fifth decade of life. It's an oil-based aldehyde, well documented in dermatological research since the early 2000s.
Most commercial soaps are water-based. The two don't
fully interact at a chemical level.
In Japan, a different ingredient has been used for
centuries.
Why Japanese persimmon, specifically?
Fermented persimmon extract — known as kakishibu — has
been used as a traditional Japanese deodorizing
ingredient for over three centuries. Craftsmen
historically applied it to wood, fabric, and silk to
address oil-based odor compounds.
Modern chemistry has explored why kakishibu works at
a molecular level. The natural tannins are astringent
polyphenols that interact with oil-based aldehydes
through chemical bonding.
WHERE TO USE IT
→ Behind the ears
→ Neck
→ Chest
→ Upper back
→ Underarms
These are areas where natural skin oils concentrate,
based on dermatological research. Customers using
traditional kakishibu-based soaps typically apply to
these areas during regular bathing.
