founder’s note
the body in transition is not a problem to be solved. it is a season to be supplied.
We make body care for the woman who has read enough — who buys hardcover books, knows the difference between a serum and a story, and wants both told plainly.

the formulation note
estrogen drops. skin holds less water. none of this is a personal failing.
Cosmetic-only by language and by law. We don’t treat, cure, or regrow. We supply what the skin now holds less of — water at the surface, the lipids it makes less of, and the tone that fades — in plain English and a small molecule list.
hyaluronic acid, squalane, stabilised vitamin C, rosehip oil.
