LEN Fragrance
Nineteenth-century recipes, reinterpreted.
LEN Fragrance was founded in Paris in 2018 by Jelena von Olnhausen, a creative director and entrepreneur who built the house around a specific historical premise: reinterpreting nineteenth-century fragrance formulas with contemporary materials and sensibility. The concept draws on archival perfumery research — formulas, ingredient lists, and olfactory descriptions from the 1800s — as source material for new compositions rather than as historical curiosities. To realise this vision, von Olnhausen collaborated with Michel Almairac, one of contemporary perfumery's most respected noses, whose credits include Rochas Man, Narciso Rodriguez For Her, and work for Cartier and Lalique. Almairac brings the technical mastery to translate historical formulas into fragrances that work on contemporary skin with contemporary raw materials. The resulting collection includes La Petite Sirène, Nuit à Versailles, and Mon Paris 1900 — each evoking a specific nineteenth-century moment without becoming museum piece or pastiche. LEN distributes through serious niche retailers and its own Paris boutique, attracting collectors drawn to the intersection of perfumery history and present-day excellence.

Each column is an era. Each colored band shows that family’s share of accord weight across every perfume the house released in that window. Bigger band = the house leaned harder on that family.
