Inside Guerlain’s L’Heure Bleue Launch In Paris

The story of L’Heure Bleue begins in 1912, when Jacques Guerlain created a fragrance inspired by the blue hour over Paris. More than a century later, the Maison returns to that same fleeting moment as the inspiration for a new interpretation, composed by Guerlain perfume creation director Delphine Jelk. While the fragrance remains connected to the emotion of the original, Jelk brings a contemporary perspective through a new approach to one of Guerlain’s most distinctive ingredients, iris.

The blue hour refers to the brief period between day and night, when the sky takes on a deep blue hue and the atmosphere seems to shift. It is this suspended quality that sits at the centre of the fragrance, expressed through an olfactive composition designed to move between freshness, powdery florals and warmth.

At its opening, an ozonic accord evokes the coolness of the open sky, before iris tincture and iris butter bring a powdery, luminous quality to the heart. Orange blossom adds a soft clarity, while vanilla tincture and Ambroxan introduce warmth and a subtle skin-like sensuality.

Central to this new interpretation is an exclusive iris tincture, developed by Guerlain over three years of research. The work has resulted in an expression of iris that the Maison describes as fresher, airier and more luminous, allowing the ingredient to take on a different character within the composition. Its powdery facets are softened by warm vanilla, creating a fragrance that moves between lightness and depth.

That story of L’Heure Bleue was then brought to life in Paris, where Guerlain recently gathered guests from around the world for an international celebration of the fragrance. Among the notable attendees was Song Hye-Kyo, alongside guests including Gina Alice and Catriona Gray.

The event unfolded across several experiences designed to explore different facets of the fragrance and the House behind it. Guests came together for a cocktail dinner on the terrace of Cheval Blanc Palace, overlooking the Pont Neuf, where they were introduced to the phenomenon of the blue hour and its connection to the original L’Heure Bleue.

Delphine Jelk also led a private olfactory workshop with Guerlain experts, offering guests an opportunity to explore the fragrance through scent and the Maison’s technical approach to perfumery.
