Sidonie Lancesseur is a French perfumer known for her elegant, natural, and emotionally charged fragrance creations. Her love for perfume began at a young age during holidays in the French countryside, where the scents of earth, wood, and flowers made a deep impression on her. After her training at ISIPCA, she started her career at Robertet, where she was mentored by master perfumer Michel Almairac, who strongly influenced her unique and minimalistic approach to composition.

Her style is characterized by short, clear formulas in which natural raw materials are central, often built around woody notes such as patchouli and vetiver. Sidonie has created iconic fragrances for houses such as By Kilian, Frapin, and Zadig & Voltaire, including Straight to Heaven, Black Phantom, and This is Her. For her, perfume is inextricably linked to memories, emotions, and personal experiences, a vision that is clearly palpable in her warm and distinctive compositions.
