Definition
Longevity is one of the two principal performance metrics for a perfume, alongside sillage. It is measured from first application to the point where the wearer can no longer perceive any olfactive impression on skin. Industry testing uses trained panels; community reviews rely on personal skin experience, which varies widely between individuals (Basenotes wiki, accessed 2026-05-27).
Longevity correlates positively with fragrance concentration (extrait > eau de parfum > eau de toilette > eau de cologne), presence of fixatives (musks, resins, ambers), skin moisture level, and application to pulse points.
Technical detail
The materials most responsible for longevity are the base note materials: macrocyclic musks, cedarwood derivatives, sandalwood, labdanum, benzoin, and synthetic ambers. Top notes by definition are the most volatile and contribute to opening impression, not longevity.
Niche perfumery communities on Fragrantica and Basenotes rate longevity on scales ranging from "poor" (under 2 hours) to "very long lasting" (8+ hours). Light aquatics and hesperidic compositions consistently score lower than oriental and woody bases.
