The Seasonal Serum

Nourishing phytoactive serum

340 €

Shipping from 29th September

Winter’s inner spark. This silken serum builds a biomimetic mesh across the skin, nourishing, energizing, and restoring harmony where cold has dulled its rhythm.

It delivers +76% hydration upon application¹ and 97% all-day comfort² without residue. Infused with our exclusive GEO3Active™ matrix—a synergy of St John’s Wort flavonoids, aquaporin-inducing rye, and evening-primrose peptides, with seasonal botanicals grown on our Grand Cru estate—cuts senescence markers in 48 hours, triggering collagen renewal that visibly softens wrinkles, re‑densifies contours and revives winter‑dull radiance.

After cleansing with the Fertile Balm, press 1–2 pumps (≈ 0.25 ml) of this silken serum onto dry skin, morning and night. It glides on like dew, disappearing to leave a breathable glow. Follow with The Seasonal Cream Autumn-Winter; by day, seal the ritual with SPF. Skin instantly feels replenished—and stays cushioned hour after hour.

The Autumn-Winter botanical blend

Every Dix Hectares formula is composed in step with the long winter rhythm of our regenerative plot.
Each cold‑season plant is chosen for how it nourishes the resting soil and shares its fortifying wisdom with both vine and skin.

Ing. I

Angelica

↑ ATP‑synthase

Angelica’s taproot drills into compact clay, ferrying minerals upward and shielding microbes from frost. We harvest at peak potency, bottling that survival wisdom so skin keeps its vitality when the cold sets in.

Ing. II

St John’s Wort

↑ SIRT3

This sun‑kissed perennial soaks up the last golden light of the year, storing it in rust‑flecked petals. On the plot it draws pollinators; on your skin it draws comfort into the depths of winter.

Ing. III

Rye

↑ aquaporin 1

Rye’s fibrous roots aerate our rich Médoc earth, making pathways for winter rain. That same water logic guides the skin—channel by channel—toward supple balance.

Ing. IV

Horsetail

↑ COL1A1 & COL3A1

An ancient reed that fortifies riverbanks, horsetail anchors loose soils and feeds them trace minerals. In our formulas it anchors the dermal matrix, keeping contours sure against the season’s erosion

Grown in regenerative soil, delivered to your skin

Each plant is harvested at peak potency, extracted from root to flower.
Dix Hectares is a living laboratory on a ten-hectare plot in southwest France. Every plant is grown in rhythm with the seasons, harvested by hand, and extracted with care. Our commitment to regenerative agriculture isn't just good for the earth- it makes a visible difference on your skin.

Questions

  • Is The Seasonal Serum suitable for sensitive skin?

    Yes, it was dermatologist‑tested on volunteers, including those with reactive complexions; 91% reported the formula felt soothing and non‑irritating.

  • Are the ingredients genuinely seasonal and sustainably grown?

    Yes. Every plant in our seasonal blend is cultivated on our plot, timed to solstice and equinox cycles, then fresh‑frozen within six hours to lock seasonal chemistry before low‑temperature ultrasound extraction. That closed loop is the heart of our terroir‑led, regenerative approach to seasonal skincare.

  • How long does the 40 ml refill last ?

    We have chosen a generous format designed to last for 3 months. For optimal results, we recommend applying a pea-sized amount to the face and neck, morning and evening.

  • What is the shelf life once opened?

    Use within six months for peak potency of fresh‑season actives; unopened, the serum remains stable for 24 months from batch date.
