What changed, in their words

The tell is never a feeling — it's a thing that stopped happening. A clean pillowcase. A grandchild who stays on the lap. A room that doesn't announce you.

Excellent 4.6/5 from verified buyers

Straight answers, before you order.

The questions people actually ask about this, answered plainly — including the two we'd rather you asked before buying than after.

How will I know it's working if I can't smell it on myself? +

You won't, from your own nose — and neither will anyone living with you after a week or so, because the nose adapts. So use the pillowcase. 2-nonenal is an oil and it leaves a faint yellow, slightly greasy mark where the head and neck rest overnight. Note what yours looks like after three nights now, and look again after three weeks. That is the measurement. It is the only one this problem offers, and it is the reason we tell you to wait three weeks before judging.

How long before there's a difference? +

Most people report a change within 7 to 10 days of daily use, and the reports almost never come from their own nose — they come from somebody else's behavior changing. The compound accumulates in skin oil over time, so it clears over time too. Three weeks is the fair test, which is why the guarantee runs 30 days and not 14.

Is this for men or for women? +

Both. Lipid oxidation is not sex-specific and the research isn't either. What differs is who buys it: roughly half our orders are placed by someone for another person in the house — a husband, a father, a mother. If that is you, the review from Sally F. further up this page is the one to read.

What does it smell like? +

Almost nothing. A faint clean, slightly earthy note that rinses away with the lather and leaves nothing on the skin. This is deliberate and it is the single most common complaint about this category — a heavily perfumed bar puts you back where you started, with two smells in the room instead of one.

Will it dry out my skin? +

It shouldn't. Tannins are astringent on their own, which is exactly why cheap persimmon bars leave skin tight, and the formula is built around offsetting that with coconut oil, glycerin and shea. If your skin is very dry or very thin, use it on the torso, back and neck — where the compound actually collects — and keep your usual gentle cleanser for the face.

Can I use it on my face and hair? +

On the face, yes, if your skin tolerates it — patch-test on the jaw first and skip it if you use a prescription retinoid or acid. Not on hair; it isn't formulated as a shampoo and the tannins will leave it feeling stripped. The compound concentrates on the upper back, chest, neck and behind the ears, so that is where the time is worth spending.

How long does one bar last? +

About a month with daily full-body use, or roughly half that if two people share one. Keep it on a draining dish rather than sitting in water and it lasts noticeably longer — a bar left in a pool of water is the most common reason people think they got a small one.

Am I signing up for anything? +

No. There is no subscription, no auto-ship and no account to cancel. You buy bars, we send bars, and when you want more you come back. We made that choice after reading what people wrote about the alternatives.

What does shipping cost? +

Free over $35, which the three-pack clears. We ship from our US warehouse and dispatch same business day on orders placed before 2pm ET. Most US addresses have it in 3 to 5 days, tracked from the moment it leaves.

What if it doesn't work for me? +

Email us within 30 days and we refund you in full. You do not need to send the bar back and you do not need a reason. We would rather refund you than have you order a second time on hope — this doesn't work for everybody, and an odor that is sudden, sharp or coming from one specific spot is a conversation for a doctor rather than a bar of soap.
