Marion Costero
Marion Costero grew up among the rolling fields of the French countryside, where the scent of lavender and fresh rain sparked a lifelong fascination with scent. She turned that curiosity into a career after completing a formal apprenticeship at a leading French fragrance house, then moved to Brazil to join O Boticário’s creative team. Her first major breakthrough arrived in 2010, when Secret Rose earned the Premio de Actualidade Cosmetica for best South American women’s fragrance. Since then she has authored more than thirty blends, ranging from the tropical vibrancy of Quasar Brasil to the nuanced accords crafted for Givaudan’s Naturality showcase in Paris. Marion balances corporate commissions with independent projects, often experimenting with AI‑assisted formulation to translate memories into scent. Her work appears in both mass‑market lines and niche collections, earning an average rating of 7.3 on industry‑wide databases. She continues to mentor emerging noses and to champion sustainability in every bottle she creates.

The signature
How Marion composes
Marion’s signature technique centers on building rich, multi‑layered bases before adding bright top notes that catch the eye. She favors natural absolutes such as Brazilian rosewood, Amazonian cacao, and Provençal lavender, pairing them with modern synthetics that extend longevity without compromising purity. Her compositions often begin with a clear emotional cue—a childhood garden, a coastal breeze—and she sketches the structure on paper before moving to the bench. She experiments with AI‑generated molecular suggestions, then refines them by hand, ensuring each molecule serves the story. The result is a scent that feels both familiar and unexpected, anchored by a clean, sustainable finish.
Philosophy
What drives Marion
Marion believes that fragrance should act as a bridge between place and feeling. She gathers inspiration from childhood hikes, local markets, and the colors of a sunrise over the Amazon. In the lab she translates those snapshots into concrete accords, letting each ingredient speak its own truth before layering them into a narrative. Technology intrigues her, yet she treats AI as a collaborator that suggests combinations rather than dictates the final scent. Sustainability guides every decision; she prefers renewable absolutes and works with suppliers who share her respect for the environment. For Marion, a perfume is a memory you can wear, a moment you can revisit.
