on sustainability · vol. 01
designed for longevity, in every sense.
Body care that lasts thirty years for the body that’s between. We hold ourselves to the same standard for everything around it — the glass, the box, the cohort cadence, the math.
the commitments
three locks. audited annually.
- 01
small batch by design
We make in cohorts of eight hundred to twelve hundred bottles, four to six times a year. We do not flash-produce on a forecast and we do not warehouse three years of stock. The trade-off is that the trio is occasionally on a six-week wait — and that is the trade-off we are happy to keep. The math is simple: small batches mean fresh formula, no expired inventory write-offs, and the ability to evolve a formulation between cohorts when the science asks for it.

refill program by spring 2026
Aluminum refill pouches, sixty percent less material than the glass primary. The primary bottle is glass with a recyclable cap; the refill arrives in a slim pouch the buyer empties into the bottle they already own. We pay return shipping on empties, recycle them through a closed-loop partner, and keep the program open to anyone — subscriber or not. The first refill ships from the May 2026 cohort.

1% for the planet, climate-neutral certified
Every order offsets at one-and-a-half times the calculated carbon footprint via verified projects. Every shipment is carbon-priced and that price is held inside the line price, not added at checkout. An annual third-party audit reconciles the numbers. One percent of revenue — not profit — flows to 1% for the Planet, distributed across body-of-water and reforestation projects the team votes on quarterly.
the thinking behind it
a body that lasts asks for a brand that does too.
The longevity word in our tagline is doing two jobs. The first is the body — body care designed to be kept on the shelf for thirty years, calibrated to the long arc of a woman’s skin in transition rather than a particular hormonal moment or a particular trend cycle. The second job is the brand itself: a small line, slow cohorts, and an honest carbon ledger, run as if the company plans to be around in 2056.
We do not believe sustainability is a marketing surface. We believe it is the operating model, and that the operating model is what makes the marketing surface trustworthy in the first place. Refill pouches that arrive in slim aluminum and re-use the glass primary the buyer already owns. Cohort production that refuses to flash-produce on a forecast. A 1% for the Planet line on the income statement before the founder takes a salary. Annual audits, third-party, results published in the journal. The receipts are the only thing that makes the words mean anything.
