Guerlain launches the new L'Heure Bleue globally on August 28, 2026. Delphine Jelk's Eau de Parfum is a modern interpretation of the idea behind Jacques Guerlain's 1912 classic and comes in 30 ml, 50 ml and 100 ml. The original continues as L'Heure Bleue 1912, giving the two fragrances distinct places in the collection.

An airy ozonic accord opens with cool, almost salty clarity. Guerlain builds the effect around Cascalone, bringing a marine and transparent movement to the composition. It is a brighter route into the blue hour than the powdery warmth long associated with the name.

Iris butter meets a specially developed iris tincture at the heart, a material that took three years to complete. The tincture should give the flower more light and air, while iris butter preserves its velvety depth. Vanilla rounds the base and gives the crystalline opening a softer, more enveloping finish.

The official campaign image places the blue-toned bottle beside the model's face among purple irises and a sky shifting toward evening. Gold lettering and the transparent heart-shaped stopper make the bottle feel jewel-like, while its deep blue gradient clearly separates the new fragrance from the amber-colored 1912 edition.
