When you smell a fragrance for the first time and then smell it again two hours later, you perceive different things. This is no coincidence: it’s the olfactory pyramid at work. Fragrances are composed of three layers of notes that reveal themselves progressively as the alcohol evaporates and the aromatic molecules interact with your skin.
The top notes: the first impact
The top notes (also called head notes or top notes) are the first you perceive when you apply a fragrance. They appear in the first 15 to 30 minutes and their mission is to create a first impression. They are the most volatile — the ones that evaporate fastest — and therefore do not represent the true personality of the fragrance.
Typical examples of top notes:
- Citrus: bergamot, lemon, orange, grapefruit
- Fresh herbs: lavender, mint, basil
- Green notes: galbanum, violet leaf
- Light spices: pink pepper, cardamom
They are fresh, bright, and sometimes the reason you fall in love with a fragrance in the store... only to be surprised when it evolves on your skin.
The heart notes: the soul of the fragrance
Once the top notes have evaporated — between 30 minutes and two hours after application — the heart notes (or middle notes, heart notes) emerge. They are the core of the fragrance, defining its true character. They last between 2 and 4 hours and represent between 40 and 80% of the total composition of the fragrance.
Typical examples of heart notes:
- Floral: rose, jasmine, ylang-ylang, peony, geranium
- Spicy: cinnamon, clove, nutmeg
- Fruity: peach, plum, red berries
- Aromatic: rosemary, thyme, sage
The base notes: what lingers
The base notes (base notes) are the last to appear and the longest lasting — sometimes for hours or even the next day on clothing. They are heavy molecules, slow to evaporate, that fix the fragrance to the skin and add depth and warmth to the entire composition.
Typical examples of base notes:
- Woods: sandalwood, cedar, vetiver, cashmere wood
- Resins and balsams: amber, benzoin, incense, myrrh
- Musk: white musk, clean musk
- Gourmand: vanilla, tonka bean, cocoa
- Oud: agarwood, one of the most prized raw materials in the world
How to read the olfactory pyramid
When you see a fragrance description with notes organized into three levels, you are reading the olfactory pyramid. The top is the most fleeting, the middle defines the character of the fragrance, and the base is what remains hours later. Knowing this structure allows you to understand why a fragrance smells different in the spray, on the wrist after 20 minutes, and on clothing the next day.
The most common mistake when buying fragrance
The main trap is to stick with the first impression. The top notes are the most striking but also the most fleeting. To know if you really like a fragrance, apply it to your wrist, wait at least 30 minutes, and then decide. What you smell from that moment on is what you will wear for the rest of the day.
