Olivier Decoster
Olivier Decoster began his career in 1987, stepping into perfumery after completing a doctorate in medicine, an unconventional path that quietly shaped everything he has built since. The dual training, scientific rigor on one hand and sensory exploration on the other, gave him a perspective rare among European perfumers of his generation. He went on to become the founder and master perfumer at HD Fragrances, where he develops niche cosmetic brands known for elegant packaging and exclusive compositions made in Europe. Beyond his own house, Decoster has carved out a distinctive presence in scent marketing, advising on olfactory identity for hotels and luxury spaces, where ambience matters as much as the fragrance itself. He has also directed Cofintra, bringing his sensibility to a broader commercial stage. A practicing physician turned nose, he continues to paint and grow roses alongside his fragrance work, each discipline feeding the others in ways his compositions reveal on skin.

How Olivier composes
Decoster favors compositions that feel composed and considered, with a European refinement visible in both his fine fragrance work and his branded environments. His palette draws on classical perfumery structures, enriched by his personal cultivation of roses, a thread that runs through several of his creations. He works with a careful hand on raw materials, allowing individual notes to register clearly rather than dissolving them into abstraction. His signature lies in atmospheres that feel curated and specific, built through precise layering and a sensitivity to how scent behaves in architectural space. Whether composing for skin or for a hotel corridor, he brings the same instinct for elegant restraint and recognizable identity.
Philosophy
What drives Olivier
Decoster approaches perfumery with the precision of a clinician and the patience of a gardener. He has spoken about scent as something that defines a space and a memory, whether a hotel lobby or a personal signature, and he builds each composition with that dual purpose in mind. His medical background informs an almost diagnostic method of working, where materials are examined for their effects on mood, behavior, and atmosphere, not merely their beauty in isolation. He treats fragrance as architecture, a layered environment to be inhabited rather than a decorative flourish. Collaboration and exclusivity guide his house ethos, and his overall outlook prizes restraint, intention, and the quiet authority of a well-made composition over trend or spectacle.
