Before creating his own brand, Kilian worked for a long time as a marketer with many perfume houses, including Dior, and later took the position of marketing executive at L'oreal.

One of the principles of the company is «eco-luxe» - luxurious, expensive bottles of Killian can be kept on the shelf for many years, and the brand produces Refile to renew the fragrance. Each bottle can be used in unlimited quantities.
