Built for the skin
you're living in now.
A question nobody
was asking.
In 2019, a dermatology researcher named Keiko Mori noticed something that had been hiding in plain sight: the patients who came to her clinic in their 40s and 50s weren't just dealing with wrinkles or dryness. Many of them were quietly embarrassed by a subtle but persistent body odor — one that didn't respond to deodorant, didn't go away with better hygiene, and that nobody in their lives was willing to talk about.
The culprit, she discovered, was a compound called 2-nonenal. It's produced when omega-7 fatty acids in aging skin oxidize — a biological process that begins around age 40 and intensifies over time. Regular soap, she found, can't touch it. Nonenal is oil-based, and water-based cleansers simply push it around without breaking it down.
What could neutralize it? The answer had been sitting in Japanese folk medicine for centuries: persimmon tannins.
"The science was already there. The ingredient was already there. What was missing was a brand willing to build something worthy of it."
Three years of
getting it right.
Keiko spent three years working with a small team of cosmetic chemists and botanical sourcing specialists to develop the first Persea formula. The challenge wasn't finding persimmon extract — it was finding the right concentration, the right processing method, and the right supporting ingredients to make it work as a daily-use product that people would actually love.
The result is a cold-processed soap bar with a persimmon extract concentration significantly higher than any competitor on the market — paired with Shea Butter, Glycerin, and Vitamin E to nourish and support the skin barrier.
No sulfates. No synthetic fragrance. No shortcuts.
Four principles that
guide everything we make.
Honesty over hype
We don't make claims we can't back up. Every ingredient in every formula has a reason to be there — and we'll tell you exactly what it is.
Science with soul
We believe that rigorous formulation and genuine care for the customer are not in conflict. The best products are built with both.
Designed for the long game
Quick fixes don't interest us. We build products that work better the longer you use them — because real skin health is built over time.
Respect for maturity
Aging skin is not a problem to be solved. It's a different skin type that deserves different — and better — care.
Small orchards.
Big standards.
Persea works directly with a network of small-scale persimmon growers in the Nara and Gifu prefectures of Japan — regions with centuries of persimmon cultivation history and ideal growing conditions for high-tannin fruit.
We visit our suppliers every harvest season. We know their names. We know their trees. That relationship is what allows us to guarantee the consistency and concentration of extract that makes Persea work.
All other botanical ingredients — green tea extract, shea butter, rice bran oil — are sourced from certified organic suppliers with full traceability from farm to formula.
