Muse Bio

Muse Bio turns menstrual blood, a renewable and overlooked biological resource, into a naturally derived, cell-free skincare ingredient produced to a documented quality standard. Founded by molecular biologist Juliette Humer, the company supplies a characterised conditioned media—available liquid or lyophilized—to skincare brands and formulators for serums, masks, and leave-on products. One hundred percent of net proceeds from the ingredient fund a separate women's-health research program. Muse Bio also runs a donor program that compensates contributors and includes STI screening, with the long-term mission of building the future of women's health on the most renewable biology in the human body.
