L'Heure Bleue
L’Heure Bleue is the eau de parfum that Jacques Guerlain composed in 1912 for Guerlain, a floral amber that the house now sells under the name L’Heure Bleue 1912, in the Les Légendaires collection. Anise and bergamot in the top notes, carnation and neroli in the heart, iris, violet, vanilla, benzoin and tonka bean in the base; inverted heart bottle, 75 ml.

Where to buy
Jacques Guerlain created L’Heure Bleue in 1912, two years before the war. Guerlain recounts its inspiration in a phrase the house still uses on its pages: the sun has set, night has not yet fallen, it is the suspended hour when man finds himself in harmony with the world and the light.
A summer evening in 1911 on the quays
Historian Élisabeth de Feydeau places the scene on a summer evening in 1911, on the banks of the Seine, where the perfumer walks with his son. She reads into it a tribute to Lily Guerlain, his wife, who would wear L’Heure Bleue all her life, and the last romantic impulse of the Belle Époque.
Sylvaine Delacourte, director of creation at Guerlain for fifteen years, sees in it a fragrance of softness and nostalgia, that of the last moments of respite before the war. Feydeau adds that Jacques Guerlain went to the front in 1914 and returned wounded in the eye.
A milestone for the house
Victoria Frolova, on Bois de Jasmin, and Feydeau agree: L’Heure Bleue is the first Guerlain to contain aldehydes, those notes that give brilliance to the floral bouquet. Frolova ranks it among the precursors of the floral oriental and cites Oscar de la Renta among its descendants; Delacourte, more severe, calls it a pale copy.
Reformulations have marked its century. Frolova notes in 2010 a heavier base in vanilla and coumarin, less animalic, less powdery, while still judging the version on sale to be beautiful. Feydeau relays Thierry Wasser, for whom its mechanics are so delicate that they cannot withstand any alteration.
The house's discourse in 2026
In 2026, Guerlain launches a new eau de parfum that takes the name L’Heure Bleue, signed by Delphine Jelk, and renames the original L’Heure Bleue 1912 on its website, in the Les Légendaires collection. Journal du Luxe and Luxe.net confirm that the old formula remains in the catalog, in a 75 ml eau de parfum and in an eau de toilette.
The house now presents L’Heure Bleue 1912 as the legend of an infinite love, a floral amber where the violet accord and iris blend into the ivory of vanilla. It sells it in a 75 ml spray bottle, with a complimentary personalized engraving, and offers it as a flanker in a 75 ml eau de toilette.

The advertising
The banks of the Seine by Clément Serveau
A watercolor by Clément Serveau, the banks of the Seine facing Notre-Dame, served as an advertisement for L’Heure Bleue; Guerlain dates it to 1948 in its archives.
The image that Guerlain still associates with L’Heure Bleue 1912 is a work by Clément Serveau, dated 1948 in the house's archives. Élisabeth de Feydeau describes this watercolor, the banks of the Seine facing Notre-Dame de Paris, and reports that it was used in an advertisement for the fragrance, a symbol of a happy Belle Époque.
Without an official face of the campaign, L’Heure Bleue has gained spontaneous ambassadors, whom Feydeau lists: Catherine Deneuve, whom Frolova also cites as a longtime devotee, Julia Roberts, Mylène Farmer and Lou Doillon. Françoise Hardy and Jean-Louis Aubert have sung its name, she adds.
For the centennial, in 2012, Guerlain released special editions in the revisited bottle, Feydeau reports. In 2026, the house's L’Heure Bleue campaign features the new eau de parfum by Delphine Jelk, and the 1912 version now appears under that vintage designation on the house's website.
