The Director of Fragrance Evaluation and Development, Sylvaine Delacourte has contributed to the development of numerous perfumes that have enriched Guerlain's olfactory heritage: L’Instant de Guerlain, Insolence, the Exclusive Collections, etc. She has an amazing intuition for discerning people's hidden depths and transcribing her client's emotional and sensory world into subtle fragrances. Colours, scents, evocations of memories and places through images, and sensitivity to different materials allow her to very quickly ""see"" the fragrance that meets complex expectations that often cannot be put into words. In the secrecy of 68, Champs-Elysées, or during a special consultation on request, Sylvaine thus offers an invitation to an astonishing journey of the senses, a unique and incredibly enriching experience, in the course of a two-hour consultation. The work of a true alchemist, translating emotions into scent.

Sylvaine Delacourte, acting as an interpreter of memories and dreams, then passes on the client's most secret desires to Thierry Wasser, the House of Guerlain's Perfumer, who will then put all of his talent to composing the perfume of a lifetime, dreamt of and idealised in one's inmost being.

From the initial idea to manufacture, through the essential checks which - like all Guerlain perfumes - the Bespoke Fragrance undergoes, approximately one year's work is required.
