Bleu de Chanel was created by Jacques Polge and launched in 2010. Wikipedia notes it was Chanel's first men's fragrance since Allure Homme Sport in 2004, and the first new men's master brand since Égoïste in 1990.
It is described as a woody aromatic, with top notes of lemon, mint, pink pepper and grapefruit; a heart of ginger, nutmeg and jasmine; and a base of labdanum, sandalwood, patchouli, vetiver, incense, cedar and white musk. An eau de parfum followed in 2014, and a parfum by Jacques's son Olivier Polge, Chanel's head perfumer from 2015, in 2018.
The launch film was directed by Martin Scorsese and starred the French actor Gaspard Ulliel, Chanel's first male ambassador. He remained the face of Bleu for twelve years, until his death in January 2022. Timothée Chalamet and later Jacob Elordi succeeded him.
