By Kilian is an eco-luxe parfum brand from Paris, created by Kilian Hennessy, grandson of the founder of the LVMH group. (The "H" in LVMH is Hennessy, the famed cognac-making family.)
Kilian Hennessy spent his childhood among the family's wine cellars in Cognac. After graduating from a program in communications and language studies, where wrote a thesis on semantics of odors in the search for a common language between gods and mortals, Kilian went on to study with some of the greatest noses in perfumery, honing his craft creating perfumes for some of the top fashion brands in the industry.
The company emphasizes ecology and sustainability through the use of refillable, reusable packaging. The perfumer's forumlas are also available for each scent on the official website.
