In 2017, Carolina Prioglio and Adrien de Bontin took over management of a farm in Burgundy that’s nestled in the rolling hills that dapple the South of France. The property, which they co-own, has been part of de Bontin’s family since 1152. His aunt, who had been operating it as a regenerative farm for 30 years, taught the couple how to implement her practices, which included composting, pollinator-habitat restoration, prohibiting pesticides and industrial tillage, and other measures that create nutrient-dense soil. The pair decided to use the rich, bountiful earth of their newly acquired land as the foundation for a skin-care company, Maison/Made, which they launched in 2019. It’s one of the first beauty brands to achieve Biodynamic certification, an accolade awarded by the Demeter Association, which typically bestows the designation to vineyards. (Biodynamic farms—self-contained, self-sufficient entities that follow the cycles of their local ecology—must adhere to strict regulations in order to maintain the classification.) Since Maison/Made grows many of the plants used to make its products, which are all made by hand in small batches on the estate, its concoctions contain a plethora of phytonutrient compounds—a distinct, sweet-smelling treat for the skin.
