The smell that just won't leave.

As skin changes with age, it creates a distinct odor often known as the 'old people smell'. It's a stubborn smell that doesn't go away, even when scrubbing harder.

Before you lean inThe worries, the thoughts and the doubts start to creep in... did they notice?

What Persimmon Actually Does

Most soaps only do half the job. Here’s the difference that matters.

Regular Soap

  • Removes only 20% of 2-nonenal from the skin
  • Can't bind with the tightly clinging molecules on the skin's surface
  • Masks the smell temporarily
Regular soap can't bind with the bad odor molecules and only masks the smell with its fragrance. Once the fragrance fades, you start smelling bad again.

Persimmon Soap.

  • Binds with 2-nonenal molecules and neutralizes them
  • Needs 90 seconds of contact time
  • Washes the molecules away completely
The result The nonenal is completely washed off for a truly clean skin surface that lasts 24 hours. Perfect for your perfume.

What Sets Our Persimmon Apart?

Most “persimmon” soaps sound the same on the label. The real differences decide whether the odor stays gone later in the day. Here’s why KERI is different:

Clinically Effective DosageWe don’t just add a little persimmon for the label. We use a Japanese kaki-tannin concentrate rated by the supplier at 97%. That number tells you the actual strength of the deodorizing material in the bar — not a vague claim.

Scent Designed to Leave CompletelyThe best smell is no leftover smell. KERI’s light washing scent rinses off completely. What’s left is clean skin so your perfume can smell exactly like itself, with nothing competing against it later in the day.

Clean Formula, No Extra JunkEvery ingredient has a job. No heavy masking fragrances, no artificial additives that stay on your skin, and no fillers that weaken the active material. Just what is needed for the 90-second method to work.

60-Day Earn-Your-Place GuaranteeUse it properly for up to 60 days. Live your normal life. If it hasn’t earned a permanent spot in your shower, contact us for a full refund. Simple as that.

First proper wash
“After just one proper use the old-lady smell I’ve been fighting for years was noticeably gone. I’ve tried so many things that claimed to help and nothing ever made a real difference until this. I was honestly shocked.”
Patricia M. ✓ Verified buyer · 60s
Later in the day
“I was worried it would leave a strong soapy smell that would clash with my perfume. It doesn’t. The light scent washes away completely and my perfume finally smells clean again later in the day instead of mixed with that other odor.”
Carolyn B. ✓ Verified buyer · 1 month
Confidence
“I used to constantly check my collar and worry if people could smell me when they got close. That constant low-level anxiety is just… gone. I feel so much more confident now. I don’t even think about it anymore.”
Barbara L. ✓ Verified buyer · 4 weeks
Actually works
“I’ve never used a soap that actually does what it says it does. Most of them just smell nice for five minutes and then you’re back to square one. This one is different. It actually works.”
Linda K. ✓ Verified buyer · 50s
Skin feel
“It’s light and refreshing, doesn’t dry my skin, and leaves zero scummy residue in the tub or on me. My skin just feels properly clean and soft afterward. That alone already made it better than every other soap I’ve used.”
Diane H. ✓ Verified buyer · 2 weeks
Thoughtful gift
“Bought this for my mom because she was getting self-conscious about the smell. She called me after a week and said she finally feels clean again and her perfume smells like itself. She’s already asked me to order more.”
Michelle T. ✓ Verified buyer · Bought as a gift
Became permanent
“I stocked up because I don’t want to run out. After a few weeks of consistent use I don’t worry about any unpleasant odors at all. My skin feels softer too. This has become a permanent part of my routine.”
Susan R. ✓ Verified buyer · 3 weeks
All-day freshness
“I love the way my skin feels so clean. It’s the first soap in a long time that makes me feel fresh all day, not just right after the shower. I’m really glad I tried it.”

Still wondering?

Let us clear up
what is left.

Short answers to the questions that matter before KERI earns a place in your shower.
What does KERI actually do?

As skin gets older, it makes an odor molecule called 2-nonenal. That's the "off" smell that keeps coming back. Regular soap struggles to remove it. KERI's persimmon tannin grabs onto that molecule, neutralizes it, and washes it down the drain.

How is this different from my regular soap?

Regular soap covers the smell with fragrance. That works until the fragrance fades. That's why you smell fresh at 8 AM and notice it creeping back by the afternoon. KERI doesn't cover the smell. It removes the molecule that causes it, so there's nothing left to come back.

How do I use it?

Three steps. Lather the places where odor lives: neck, chest, back, underarms and behind the ears. Wait 90 seconds. That pause is when the persimmon does its work. Then rinse. Once a day, in your normal shower.

How fast will I notice a difference?

Most people notice after the very first shower. Do your own sniff test that evening. With daily use, the clean feeling holds all the way to your next shower.

Will I smell like soap afterwards?

No. KERI's light washing scent rinses off with the lather. You step out smelling like nothing at all. That's the goal: clean skin, with no leftover smell of any kind.

Can I still wear my perfume?

Yes, and it will smell better. With no odor underneath fighting it, your perfume finally smells the way it does in the bottle. In our blind tests, 8 out of 10 women said their perfume lasted hours longer when they used KERI first.

Is KERI for men too?

Yes. 2-nonenal shows up in both men and women from around age 40, and the scent is neutral, so one bar works for both of you. It also makes an easy, discreet gift for a parent or partner. Nothing on the box mentions odor.

How long does one bar last?

About two weeks of daily showers. That's why the 6-bar pack, about 3 months of supply, is our most popular choice. Automatic refills save you another 20% and can be cancelled anytime.

Do I have to keep using it forever?

Honest answer: KERI is soap, not a cure. Your skin keeps making the odor molecule as part of normal aging. So the smell stays gone for as long as KERI is part of your shower routine. One wash a day is enough.

What if it doesn't work for me?

Then it's free. Use it daily with the 90-second method. If you don't feel the difference within 60 days, contact us and we refund you in full. No questions, no hoops.

When will my order arrive?

We offer standard shipping, with most orders arriving within 6-7 days from the time of ordering. Need it sooner? We also have express shipping options at checkout.
