Benefits
  • Neutralizes 2-nonenal, the compound behind age-related odor
  • Persimmon (kakishibu) binds odor instead of masking it
  • Coconut oil, hyaluronic acid & collagen — soft, hydrated skin
  • Gentle, sulfate-free daily clean
  • For everyone 40+ — men & women
How Does It Work?

After about 40, the body produces more 2-nonenal — the compound behind age-related odor. Ordinary soap rinses around it, so it rebuilds within hours. Persimmon tannin (kakishibu) binds to it and helps break it down at the source, while coconut oil, hyaluronic acid and collagen condition the skin.

Ingredients
  • Persimmon (Kakishibu) — targets the nonenal behind aging odor
  • Coconut Oil — deep moisture for dry, mature skin
  • Hyaluronic Acid — attracts & locks in hydration
  • Hydrolyzed Collagen — supports skin firmness
  • Green Tea Extract — antioxidant support
  • Natural Soap Base — gentle, sulfate-free clean

How persimmon (kakishibu) works.

Persimmon tannin — kakishibu — is different. Instead of rinsing past nonenal, it binds to it and helps break it down at the source, like a degreaser lifting what water alone can't touch.

It cleans without stripping. Coconut oil, hyaluronic acid and hydrolyzed collagen condition mature skin while you wash — no harsh sulfates.

A ritual, not a routine. One bar, in your normal shower. It doesn't cover the problem with fragrance — it removes it.

Read this before your next bar of soap

It's not poor hygiene. After a certain age, it's chemistry.

You shower every day. Yet sometimes there's still a faint, stale note a normal bar just doesn't remove.

Around our 40s, the body starts producing more of a compound called 2-nonenal — the molecule behind what's politely called "aging odor." Ordinary soap washes around it, so within hours it rebuilds, no matter how hard you scrub.

It isn't about cleanliness. It's chemistry — and most soap simply leaves it behind.

You can't smell it on yourself. The people close to you can.
Straight answers

Frequently asked

How fast will I notice a difference?

Many people notice a difference after the very first wash. Freshness builds over the first week of daily use.

What causes this kind of odor?

After about 40, the body produces more 2-nonenal. Ordinary soap washes around it, so it rebuilds within hours. Persimmon tannin (kakishibu) binds to it and helps break it down instead.

Will it dry out my skin?

The opposite. Coconut oil, hyaluronic acid and hydrolyzed collagen help condition your skin while you wash — no harsh sulfates.

How and where do I use it?

Daily, in your normal shower. Focus where odor tends to build: behind the ears, the back of the neck, the chest and the back.

Is it for men or women?

Both. Age-related nonenal affects everyone — this bar is made for anyone who wants to feel genuinely fresh again.

Why does it cost more than regular soap?

Real Japanese persimmon extract at a concentration that actually works isn't cheap — plus skincare-grade hyaluronic acid and collagen.
