Everything you might want to know about Kakishi, the science behind it, and how it fits your routine.

PRODUCT & INGREDIENTS
What's actually in Kakishi?+
Persimmon extract (rich in natural tannins), coconut oil, olive oil, and a gentle saponified soap base. No harsh sulfates, no synthetic fragrance, no added dyes.
Is it safe for sensitive or mature skin?+
The coconut and olive oil base is formulated to be gentle, and most people find it non-drying. That said, sensitivity varies from person to person - a small number of users find any new soap, including this one, feels drying at first. We recommend a patch test on the inside of your wrist if you have known sensitivities.
Does it have a strong fragrance?+
No. The scent comes from the persimmon extract itself, not an added synthetic fragrance. Most people describe it as light and clean rather than strong or floral.
Is it cruelty-free?+
Yes, Kakishi is cruelty-free.
Why does it cost more than drugstore soap?+
Persimmon extract and natural tannins cost more to source than mass-market fillers. Most customers who stick with it say it's worth it for the quality and how long a bar lasts - but we get it's a real investment compared to a $3 bar, and it isn't for every budget.
Where is Kakishi made?+
Kakishi is produced by a trusted manufacturing partner specializing in traditional persimmon soap formulations. [Précise ici le nom/pays réel de ton fournisseur AliExpress une fois finalisé.]
THE SCIENCE
Why does body odor change as we age?+
Around midlife, skin surface lipids change - in particular, a fatty acid called palmitoleic acid increases and becomes more prone to oxidation. When it breaks down, it produces a compound called 2-nonenal, first identified by Japanese researchers in the early 2000s. It's linked to the distinct scent many people notice becoming more prominent with age. It's simply biology, not something you're doing wrong, and it's rarely talked about openly.
How does persimmon relate to this?+
Persimmon extract is naturally rich in tannins - plant compounds long valued in Japan for their astringent, binding properties. Traditionally, kakishibu (fermented persimmon juice) has been used for centuries in textiles and paper specifically for its ability to bind organic compounds and odors. Kakishi soap is built around that same ingredient.
Does Kakishi "neutralize" 2-nonenal?+
We want to be careful and honest here: tannins are traditionally used for their odor-binding, astringent properties, and that's why we chose persimmon as our core ingredient. But we haven't run a clinical study on this exact bar, so we're not going to tell you it "neutralizes" or "eliminates" odor as a proven medical fact. What we can say is that it's a real, traditional ingredient chosen for a real reason - not a synthetic fragrance layered on top to mask something.
USING KAKISHI
How do I use it?+
Use it daily as part of your normal shower or bathing routine, just like any cleansing soap bar. Lathering it with a washcloth or mesh soap bag helps it foam more and last longer.
How long does one bar last?+
It varies by how often you use it and how you store it. Most people get 2-4 weeks with daily use - keeping the bar on a draining soap dish between showers helps it last longer.
Is this a substitute for deodorant?+
No. Kakishi is a cleansing soap bar for your daily wash routine - it's not a substitute for deodorant if you use one.
Can men use it?+
Yes. Kakishi isn't formulated or scented in a way that reads as gendered - anyone whose skin and body are changing can use it.
