Definition
Dry-down is both a technical descriptor for the phase sequence of a formula and colloquial shorthand among enthusiasts for the heart-to-base transition specifically. In community usage on Fragrantica and Basenotes, "the dry-down" often refers to what a fragrance smells like 1 to 3 hours in, not the entire evolution.
The concept entered widespread English-language perfumery vocabulary in the 1990s through professional evaluation training and was subsequently popularized by online community writing.
How it works
The dry-down is structured by the volatility differential of fragrance materials. Top notes (citrus, light aldehydes, fresh aromatics) are highly volatile and evaporate within 15 to 30 minutes. Heart notes (florals, spices, some woods) last 1 to 4 hours. Base notes (resins, musks, heavy woods, ambers) persist for many hours or days on skin and fabric (Société Française des Parfumeurs EN, accessed 2026-05-27).
Skilled perfumers design transitions between phases to feel smooth and cohesive: abrupt phase changes can create a dissonant experience. The dry-down is a critical criterion in professional fragrance evaluation; critics often assess perfumes across multiple sittings to capture the complete arc (Now Smell This, Bois de Jasmin, accessed 2026-05-27).
