In business in the city of lights for nearly two centuries, this iconic perfumerie dating to 1912 is one of the world's oldest perfume houses. A bit of old-style glamour at home on the Champs-Elysee, Guerlain occupies an uncommonly beautiful space merging Art Deco decor with designer Andrée Putnam's handcrafted gold mosaic. The perfumer's 300+ scents feature compositions taking inspiration from sweets: Vanilla and amber are often included ingredients. Dusky L'Heure Bleu is among Guerlain's most iconic perfumes, an original composition dating to 1912. But the popular unisex Jicky scent, which was created in 1889, is the oldest continually produced fragrance.
