The Top Notes of a fragrance represent the first impression. It is hugely important that the top notes not only succeed at luring you in, but also smoothly transition into the heart of the fragrance. The top notes are also the first to fade given their light molecular structure.
The Middle Notes are considered the heart of the fragrance. They last longer than the top notes and have a strong influence on the base notes to come. It is often a smooth combination of floral and fruit notes; sometimes infused with spices like cinnamon, nutmeg and cardamom.
The job of the Base Notes is to provide a lasting impression. These often-rich notes linger on the skin for hours after the top notes have dissipated. The base notes mingle with the middle notes to create the full body of the fragrance.
