Bleu Noir Eau de Toilette Extrême lends new elements of mystery and magnetism and signals fierce confidence. Bleu Noir Eau de Toilette Extrême is intriguing; it’s a fresh scent that’s both enigmatic and strong. Crisp, cool and vibrant: signature musc remains at the heart of the fragrance and is juxtaposed with icy citrus notes—mandarin green and basil— animated by sensual woody notes—blue cedar, black ebony and citrus.
