I’m 65. Here Are 5 Things That Finally Stopped The “Old, Musty” Smell My Daughter Noticed On Me (A Second Daily Shower Never Did)
Japanese researchers gave the smell a name in 2001. Regular soap leaves it sitting on your skin. A persimmon bar cleared it from mine inside a week.

My daughter came for Sunday dinner last spring. At the door she hugged me, held it a second, and pulled back.
Later, while we did the dishes, she said it as gently as she could. “Mom, you smell a little odd. Kind of old and musty.”
I went upstairs and smelled my own blouse for a long time.
I couldn’t smell a thing. That turned out to be lesson one.
You can’t smell it on yourself, so stop trusting your own nose
Your nose tunes out your own scent within minutes. It’s the same reason you stop noticing your own kitchen after you’ve cooked in it.
So the only people who get an honest read on you are the ones who walk in fresh: a grandchild, a friend in the car, the cashier who leans back half a step. Once I started paying attention, I noticed the window got opened whenever I sat down in my son’s small apartment. Nobody ever said why.
If the people close to you have gone quiet about it, that silence is the polite version of what my daughter said out loud.
Scrubbing harder does nothing, because the smell is an oil your skin makes after 40
My first move was the obvious one. A second shower every evening, a loofah, a heavier body lotion with a vanilla scent. Two weeks of that left my skin dry and itchy, and the musty note was still on my collars.
The reason has a name: 2-nonenal. Japanese researchers identified it in 2001. As we age, the natural oils on our skin oxidize and leave behind this greasy, stale-smelling compound. It collects on the back of the neck, behind the ears, across the chest and shoulders, and it soaks into collars and pillowcases.
Nonenal is oily, and ordinary soap is built to lift sweat and dirt. It rinses right past it. You come out of the shower clean and still carrying the one thing people notice.
In Japan they’ve used persimmon tannin for this for years, and the mechanism is simple
That same night I went looking and found kakishibu, which is fermented persimmon tannin. Japanese families have used it for a long time, and persimmon soap is a common answer to aging odor over there.
Tannin grabs onto nonenal. When you lather, the tannin binds to the oily compound so it rinses away with the foam, instead of a fragrance trying to sit on top of it.
I ordered a bar of SAWUMI, a persimmon soap made with fermented persimmon extract and green tea. I used it once a day, focusing on my neck, behind my ears and my chest, for about a minute before rinsing.
See the bar I use, and today’s Buy 1 Get 1 FREE deal ›The pillowcase test told me it was working before anyone said a word
Here is the test I wish someone had given me two years earlier. Put a fresh pillowcase on, sleep on it for a week, then smell it first thing the next morning before you’ve been around anything else.
Before the switch, my pillowcase had that musty note after three nights. After a week on the persimmon bar, I pressed my face into it and there was nothing there. Just cotton.
I wasn’t the only one checking. These are from SAWUMI’s own customer reviews:
“Sceptical at first, it’s soap after all. But within a week the difference on my collars was undeniable. It’s the real kaki extract, I checked the label.”
Verified customer✓ Verified buyer“Bought it for my husband after 40 years of marriage. He now uses it more religiously than I do. The pillowcase test does not lie.”
Verified customer✓ Verified buyer“My daughter hugged me and pulled away. She said I smelled ‘odd, like old musty’. I was mortified and ordered this soap that same evening. I’ve been using it for 4 months now, and last week she asked me what’s different about me. Did I tell her? NO!”
Verified customer✓ Verified buyer“I’m 69 and had started worrying about that ‘old person smell’ I remembered from visiting my aunt years ago. After only a few days of using this persimmon soap, my granddaughter mentioned how fresh I smelled.”
Verified customer✓ Verified buyerA few weeks later my daughter hugged me at the door again, and this time she didn’t pull back. She stayed for dessert, and she sat right next to me on the couch.
Before you buy any persimmon bar, find one word on the label: kakishibu
Persimmon soap got popular fast, and marketplace listings are full of bars where the label tells you very little. The tannin is the part that does the work, so it has to be in the bar. Check the ingredient list for persimmon (kakishibu) extract near the top, a full-size bar, and a company that will refund you if it doesn’t work.
SAWUMI lists fermented persimmon extract and green tea extract on the label, in an olive oil, coconut oil and glycerin base, so my 65-year-old skin doesn’t feel stripped. It’s a full 100g bar that lasts me about five weeks.
