By Kilian

Founded in Paris in 2007 by Kilian Hennessy —grandson of the founder of the multinational luxury LVMH Group and direct descendant of the historic cognac-producing Hennessy family—, By Kilian is a creator-led luxury fine fragrance house focused on nocturnal, sensual, and sustainable luxury.

The technical and conceptual difference of By Kilian lies in its philosophy of treating perfume as a reusable and collectible art object. The brand's bottles are designed to be refilled indefinitely using special refill bottles (refills), eliminating the use-and-discard mindset. Olfactorily, the brand stands out for complex fragrance compositions with high concentrations of natural raw materials, frequently inspired by the woody and vanilla aromas of the oak barrels from the family's cognac stock.

As a signature aesthetic detail, the presentation cases for its core collections are designed as heavy black wooden security boxes or small chests secured with a metal lock, evoking collector's cabinets and the tradition of 19th-century luxury cigar humidors.
