"Guerlain’s in-house perfumer Thierry Wasser is shining new light on the iconic fragrance L’Heure Bleue. Under his influence, the soft, elegant scent of the original is lit up with a fresh, contemporary sparkle.This modern olfactory interpretation immerses us in a magical and mysterious “Paris by Night” feel bridging dream and reality, the twilight becomes enchanting and magnetic. Night time fills the air: it is “L’Heure de Nuit.”
The period in which it was launched—2012—was a time of reflection and reinterpretation in perfumery. The fragrance industry was revisiting its great classics, offering modern “flankers” that honored history while appealing to new audiences. Fashion, too, was in a moment of blending eras: vintage-inspired silhouettes were paired with sleek, modern tailoring, and perfumery mirrored this balance of heritage and reinvention. Thierry Wasser, Guerlain’s in-house perfumer, created L’Heure de Nuit as a luminous floral woody musk—a composition that nodded to the romantic powderiness of L’Heure Bleue, yet replaced its melancholic depth with radiant sparkle. Women of the early 2010s, increasingly global and independent, might have related to a fragrance called “The Hour of Night” as both an invitation to mystery and a statement of elegance—something to wear from evening into late-night hours, when the city and its secrets belong to them.
Interpreted in scent, L’Heure de Nuit takes the powdery softness of iris, heliotrope, and violet from L’Heure Bleue, but brightens them with fresher, more transparent notes and modern musks. The result is less wistful and more radiant—a “nighttime” fragrance that suggests shimmer rather than shadow, enchantment rather than melancholy. Compared to other fragrances of its time, it fell in line with the trend of modern reinterpretations of classics (such as Chanel’s Les Exclusifs or Dior’s reissues), but its artistry lay in Guerlain’s ability to reinterpret its own masterpiece in a way that felt authentic, refined, and relevant to contemporary tastes.
L’Heure de Nuit ultimately bridges two worlds: it honors the poetic heritage of Guerlain while offering a more sparkling, wearable vision of elegance for modern women—a perfume that celebrates the night as a time of beauty, mystery, and enchantment.
