Fragrance notes are the individual scents that make up a perfume, arranged in three layers: top, heart and base. Top notes are what you smell first and fade fastest. Heart notes are the main body of the scent. Base notes are the deep, long-lasting foundation. A perfume unfolds through these layers over hours, which is why it smells different at first spray than it does later in the day.
Buying tip hidden in the pyramid: the base notes are what you and everyone around you will smell for most of the day, so read those first when choosing a perfume. The pretty citrus opening is gone within fifteen minutes.
The three layers of a fragrance
| Layer | When you smell it | Typical notes |
|---|---|---|
| Top notes | First spray, first 5-15 min | Citrus, bergamot, fruit, fresh herbs |
| Heart notes | After tops fade, next few hours | Florals, spices, fruits, green notes |
| Base notes | The dry-down, lasts longest | Woods, amber, musk, vanilla, oud |
Why a perfume changes through the day
Notes evaporate at different speeds. Light top notes lift off first, revealing the heart, which eventually settles into the long-lasting base. That evolution is why the dry-down defines a fragrance far more than its opening, and why base-heavy scents feel richer and last longer.
How to use notes when choosing a perfume
Read the base notes first. They define what you will actually wear for hours. If you love warm, cosy scents, look for vanilla, amber and woods in the base. If you prefer fresh, look for citrus and clean musks. Concentration then decides how long that base holds; see what is extrait de parfum. Ready to browse by profile?
