The seasonal philosophy of Dix Hectares:

• An Autumn-Winter Eye Cream in October, that is skincare.

• A Spring-Summer Cream in May, that is skincare.

• Changing creams with the rhythm of the seasons, that is skincare.

• Harvesting rye and barley before winter, that is skincare.

• Letting the earth rest when the cold sets in, that is skincare.

• Plucking a plant at the height of its bloom, that is skincare.

• Freezing it within six hours of harvest, that is skincare.

• Letting comfrey ferment in hazelnut oil, that is skincare.

• Growing your own active ingredients on ten hectares, that is skincare.

• Cultivating your skin like a garden, that is skincare.

• Knowing that January does not ask for what July demands, that is skincare.

At Château Montrose, every parcel of land seems destined for vines. Almost. When Martin and Olivier Bouygues acquired this Saint-Estèphe Second Grand Cru Classé in 2006, ten hectares remained as meadow. Too fertile for vines, which yield their best only when forced to seek nourishment deep within the earth. Fifteen years later, Charlotte Bouygues saw this anomaly in a different light.

Beauty had long been on her mind. After her studies, she spent three years at L’Oréal in New York, then joined TF1, all while quietly nurturing the idea of her own house for nearly a decade. An article on Carole Bamford and her English farm, Daylesford, sparked a revelation: why not start from the soil to create a way of life? She returned to Saint-Estèphe, turning the family meadow into a living laboratory. Across these ten hectares, plants are grown using regenerative agriculture—practicing crop rotation and nurturing soil life. They become the raw materials for skincare, their active ingredients extracted and formulas developed in a laboratory built right on the estate.

Dix Hectares calls this approach “geodermy”: treating soil and skin as sister ecosystems, aligning rituals with the cycle of the seasons. For now, the story comes full circle on Rue de Sèvres. In 2026, Dix Hectares arrived at Le Bon Marché—the very place where Charlotte’s grandmother used to take her as a child to admire the windows and shop, a ritual she now shares with her own children.
