How fragrance notes actually work
Top, heart, base — and why the pyramid is a simplification worth understanding anyway. A plain-language guide to reading a fragrance before you buy it.
The pyramid is a timeline, not a recipe
Top notes are simply the molecules that evaporate fastest. Base notes are the ones that stay. Nothing in a bottle is "layered" — it is all mixed together, and what you smell changes because different components leave at different rates.
Volatility in practice
- Top (0–20 minutes): citrus, light aromatics, aldehydes
- Heart (20 minutes–2 hours): florals, spices, tea, fruit
- Base (2 hours+): woods, resins, musks, vanilla, ambers
Reading a note list
If a fragrance lists bergamot, jasmine, and sandalwood, you are being told the arc: bright open, floral middle, soft creamy close. If it lists oud, labdanum, and leather with nothing volatile on top, expect it to smell the same in hour four as in minute one.
Why heat matters
Warm skin and warm weather accelerate evaporation. The same fragrance sprayed in July finishes its arc far faster than in January — which is why Aura biases recommendations by live temperature and humidity.
