Have you ever noticed that a perfume doesn't smell quite the same when you spray it and a few hours later? It's not your imagination: a perfume evolves on the skin in three stages, called top, heart and base notes. Together, they form the olfactory pyramid. Understanding this structure helps you choose your perfume better and know why you like it.
Key takeaway: a perfume reveals itself in three stages: the top notes (the first few seconds), the heart notes (its character) and the base notes (the lasting trail). To really judge a fragrance, you need to let it evolve on your skin. Discover our extraits de parfum concentrated at 30%.
What is the olfactory pyramid?
The olfactory pyramid describes how the different ingredients of a perfume reveal themselves over time, according to their volatility. The lightest notes come through first and evaporate quickly; the heaviest appear later and last a long time. That is why a perfume is "read" from top to bottom, like a pyramid.
Top, heart and base notes
Top notes
These are the first impressions, the ones you notice as soon as you spray. Fresh and volatile, they last from a few minutes to around fifteen minutes. They often include citrus (bergamot, lemon), green or aromatic notes.
Heart notes
They appear as the top notes fade and form the perfume's true character. Rounder and more persistent, they last several hours. Flowers, fruits and spices usually come through at this stage.
Base notes
These are the deepest and most tenacious notes: they fix the perfume and make up the trail that stays on the skin and clothing. Woods, amber, vanilla, musk or patchouli are often among them. They are what gives longevity.

Why does it help you choose?
Understanding the pyramid helps you test a perfume intelligently:
- Never judge a perfume only on the first spray: those are the top notes, the most fleeting.
- Wait 15 to 30 minutes to discover the heart notes, which reveal its true character.
- Smell it again after several hours to appreciate the base notes and its longevity.
This is also why we offer samples: they let a perfume evolve on your skin before you choose. And because concentration affects longevity, find out the difference between eau de parfum and extrait.

Frequently asked questions about perfume notes
What is the difference between top, heart and base notes?
Top notes are the first you notice and the most volatile; heart notes form the perfume's character after a few minutes; base notes are the most tenacious and make up the trail that lasts several hours.
How long do top notes last?
Top notes usually last from a few minutes to around fifteen minutes, before giving way to the heart notes. That is why you shouldn't judge a perfume too quickly.
Why does my perfume smell different over the course of the day?
Because it evolves according to the olfactory pyramid: the lightest ingredients evaporate first, then the heaviest are revealed. Your skin, its temperature and its hydration also influence this evolution.
