Handmade by Yana · Every bar stamped with a Y

Soap, taken far too seriously.

Small-batch bars made with love, goat milk, botanical clays, and a frankly unreasonable amount of science. You cannot buy them. You probably cannot get one. We're told this is called a "strategy."

Batch size: tiny Formulas: weighed to the gram Availability: no
Cream-colored soap bar stamped with a Y, stacked on a honeycomb-textured bar

Breakfast Cereal, posing. It knows.

The science

Made with love. Verified with math.

Every recipe starts as a spreadsheet: oils balanced for lather and hardness, clays chosen for what your skin actually needs, essential oils blended like perfume and measured like medicine. Goat milk for creaminess. Salt bars cured until they could survive a polar plunge. Nothing rushed, nothing random, nothing you can't pronounce without at least learning something.

To the gram

Every formula is weighed, logged, tested on willing family members, and argued about.

Zero shortcuts

Cold process, hot process, long cures. The slow way, on purpose, every time.

One stamp

If it isn't stamped with the Y, it isn't one of ours. If it is — someone likes you very much.

The collection

Sixteen bars currently in circulation.

Each one has a secret opinion of itself. Press the 🤫 to hear it. Full formulas are under the ⚗ — because around here, the ingredients list is the marketing.

Acquisition

How to get a bar.

There are exactly two ways to acquire one. One: know someone who has already received a bar. Two: get on the list.

Can I buy one?

No. There is no shop, no cart, no checkout. There is soap, and there is the list.

When does the list open?

The list has never been open. That's what makes it the list.

Who is on the list?

Friends. Family. People who have never once asked about the list.

I know Yana personally.

That is not a question. But now you're getting warmer.

If a bar ever finds its way to you — you were on the list all along.

Excellent taste.

Unfortunately, these bars cannot be bought — only given. There are exactly two ways to receive one: know someone who already has a bar, or be on the list.

Sorry, the list is closed.

Yana shares her soap with friends and family. If you know someone who already has a bar… you know what to do.
