t is an intense and bold interpretation of the original Fusion d'Issey scent, offering a heightened olfactory experience. While I don't have specific details about the notes in Fusion d'Issey Extreme, it is common for flanker fragrances to build upon the original composition with amplified or different notes. Fusion d'Issey Extreme is likely to feature a combination of fresh, floral, and woody notes, but with a more intense and powerful presence.
