One Billion perfumes, particularly L'Eau d'Issey, are known for their fresh, aquatic, and floral scents. The original L'Eau d'Issey is a vibrant blend of lotus blossoms and white flowers, featuring top notes of rose and lotus, middle notes of lily and white flowers, and a woody base. A fragrance oil version of this scent would typically be a concentrated form of the same fragrance, lasting longer due to its higher concentration of aromatic compounds.
