Similarity is based on note and accord overlap, not molecular analysis.
Differences come from accords and community votes on longevity and sillage.
The main accords of L Eau d Issey Pour Homme are citrus and aromatic. It opens with Yuzu and Lemon, reveals Blue Lotus and Lily-Of-The-Valley at its heart, and dries down to Tahitian Vetiver and Musk. It lasts long and projects moderately; people reach for it in spring and summer, mostly by day.
