Which one hits closest to home?
Just pick the one you felt in your gut.
I never smelled bad. Then menopause happened.
Lifelong clean person, suddenly a problem
I have a literal deodorant graveyard on my shelf.
Tried everything, nothing stuck
I shower twice a day and it still comes back by 10am.
Extreme hygiene, zero results
Someone told me. And I've been devastated since.
External confirmation is the worst kind

How would you describe it?
The type of smell tells us which compounds are involved.
Musty, waxy, slightly onion-y
Classic 2-nonenal signature — the kareishu profile
Strong, sharp — worse when I'm warm or stressed
Could be nonenal plus sweat interaction
I can't really describe it — it just smells different than before
Early stage change — harder to name
More in my clothes than on my skin directly
Nonenal persists in fabric even after washing
3 of 6
How quickly does it come back after you shower?
Timing is one of the strongest indicators of nonenal versus other causes.
Mostly at the end of the day after activity
Possible sweat or mild nonenal
By mid-morning, even without much movement
Nonenal doesn't need heat or activity — it's always there
Almost immediately — I feel like I can't keep up
High production rate, established nonenal load
I wake up in the morning already smelling it
Nonenal in bedding and skin — significant load

What's already in the graveyard?
Pick the closest match.
Just regular soap and deodorant so far
Haven't gone further yet
Clinical-strength deodorants, antibacterial wash
The right instinct. The wrong compound.
Multiple things — Hibiclens, diet changes, glycolic acid, doctor visits
Exhausted the conventional options. This confirms nonenal.
Tried a persimmon soap already — it didn't work
You tried the category. Not the formula. That matters.
5 of 6
Where are you in the seesaw?
Estrogen levels directly determine how much 2-nonenal your body produces.
Still menstruating — not in perimenopause yet
Lower baseline production
Perimenopause — things are getting unpredictable
Estrogen declining, nonenal rising
Post-menopause — periods stopped
Sustained low estrogen means ongoing production
On HRT — hormones are managed
Helps, but doesn't eliminate nonenal production
6 of 6
What do you most want back?
This shapes which solution fits you best.
To hug my family without anxiety
Grandkids, partner, being physically close again
Confidence with a partner or dating again
Intimacy, feeling attractive, not overthinking every moment
Not thinking about it at work or in public
Professional confidence, social ease
Just peace of mind — to stop thinking about it completely
The background anxiety, gone

Early Stage · Starting Advantage
You're catching this
before it takes over.
Your nonenal production is beginning. The women who start now stay ahead of it. The ones who wait spend the next two years building a deodorant graveyard.
Your Nonenal Level
MinimalModerateSignificant
Nonenal is building but hasn't fully established yet. Starting Tsūki now means you'll maintain a clean baseline rather than trying to reverse an entrenched pattern.
One bar is the right starting point. 6 weeks. If you notice a difference — and at this stage most women do within the first few days — a 2-bar supply covers you for the season.

"I started early and my friends in their 50s who didn't say they wish they had."

"I'm 47. Perimenopause just started. I feel completely confident. That used to be a question mark."

Active Production · Fix the Right Target
Your soap has been
solving the wrong problem.
Your profile matches the classic nonenal pattern. The compound is established. Every product you've tried targets bacteria or sweat. Nonenal is neither.
MinimalModerateSignificant
The smell returning within hours of showering is the defining nonenal signal. Your soap cleans the surface. Nonenal lives in the lipid layer underneath. Water cannot reach it.
Persimmon tannins at the correct concentration (the Osaka Formula) are the only compound that chemically binds to nonenal and eliminates it. Not covers it. Eliminates it.
At your production level, most women notice a real difference within 3 to 5 days. Some on the first shower. The 2 to 3 minute contact time is what activates the chemistry.

"Week two I realised I hadn't thought about it once. Just went about my day. My husband said I seem like myself lately."

"Used it 4 nights before my first date in 10 years. Gone. We've been together 4 months."

Significant Load · You Need the Full Run
You've been dealing with this
longer than you should have.
Your profile shows sustained nonenal production that conventional products have consistently failed to address. You're not broken. You've been using the wrong tool for a long time.
MinimalModerateSignificant
Everything you tried was the right effort aimed at the wrong compound. Deodorant targets bacteria. Hibiclens targets pathogens. Glycolic acid targets skin cells. None of them target nonenal because none of them were built to.
At a significant load, the contact time is critical. Leave the lather on for the full 2 to 3 minutes. The tannins need that dwell time to work through the accumulated compound in your lipid layer.
A 3-bar supply is strongly recommended for your profile. 18 weeks gives you a full consistent run — the difference between managing the smell day-to-day and actually getting ahead of it.
Women at this stage say

"I tried everything. Hibiclens, glycolic acid, two persimmon soaps that did nothing. This worked after the second shower. I cried in the bathroom."

"My daughter told me very gently. I was devastated. After one week she hugged me at the door instead of from across the room."
