Fragrance Notes Explained: Top, Heart and Base Notes

Short answer: fragrance notes are the stages a scent goes through on your skin. Top notes are what you smell first, and they fade within minutes. Heart notes take over and form the main character for the next hour or so. Base notes come through last and can stay for many hours. That’s why a perfume never smells quite the same at 9 am as it did at 8.

Once you understand notes, product pages start to make sense, and you’ll stop judging a scent by its first sniff. That’s the most common mistake we see.

Why a scent changes over time

A perfume is a mix of molecules of different sizes. Small, light ones float off your skin quickly. Big, heavy ones take hours. So the smell you notice shifts as each group evaporates in turn. Perfumers plan for this and arrange the materials into three tiers, usually drawn as a pyramid.

The pyramid idea, explained in more depth in Wikipedia’s article on notes in perfumery, goes back to the 19th century. The perfumer François Coty, who made the famous Chypre in 1917, was one of its pioneers.

The three tiers in detail

Top notes: the first impression

Light, bright and quick to fade. Citrus (bergamot, lemon, mandarin), fresh herbs like basil and mint, and spices like pink pepper usually sit here. Perfumers use them to grab your attention. In the classic system, top-note materials have an evaporation coefficient of 1 to 14, the fastest of all.

Heart notes: the real character

They appear just before the top notes disappear and last from about twenty minutes to an hour. Flowers like rose, jasmine and neroli live here, along with lavender and warm spices. When someone says “this smells floral”, it’s usually the heart they’re describing.

Base notes: what stays

Woods, musk, amber, vanilla, oud and resins. They’re often not obvious until 30 minutes in, during what perfumers call the dry-down. Some, especially musks, can still be noticed more than 24 hours later. Base notes also slow down the lighter notes above them, which is why they’re called fixatives.

How to read the notes on our product pages

Every oil in our shop shows a short line of three notes. They’re listed from top to base, so you can picture the whole journey at a glance:

Want to explore one note? We have a collection for each of the big ones: bergamot, jasmine, rose, saffron, sandalwood, musk, vanilla and amber.

Three mistakes notes help you avoid

1. Judging in the first minute. The opening is the least representative part. Wait at least 20 minutes before you decide.
2. Testing three scents at once. Notes overlap and your nose tires quickly. Try a maximum of three in a session, on separate strips or separate spots, and smell coffee beans or your own sleeve in between.
3. Buying for the top note alone. If you love a citrus opening but the base is heavy vanilla, you’ll spend most of the day smelling vanilla. Check the last note in the list.

Building your own blend? The same three-tier logic applies. A blend with no base fades fast, and one with too much base smells flat. Our home perfume recipe shows how to mix a finished oil into a spray.

Notes, families and lasting power

Notes describe the journey of one scent. Families group scents by their overall character, such as fresh, floral, amber or woody. Read fragrance families explained to find yours. And since base notes do most of the work in the late hours, they’re also the key to lasting power. More on that in how to make your perfume last longer.

Want to know what a single note smells like? Our ingredient guides go one note at a time: musk, sandalwood, rose, amber, saffron and vanilla. To combine notes yourself, see how to layer fragrance oils.

Questions we get a lot

What does “dry-down” mean?

The final stage of a scent, once the top and most of the heart notes have gone. It’s what you, and the people around you, smell for most of the day.

Why does a perfume smell different on me than on my friend?

Skin type, warmth and even diet change how quickly each note evaporates. Oilier skin tends to hold scent longer than dry skin, so the same oil can lean fresher on one person and warmer on another.

Are some notes better for long wear?

Yes. Musk, amber, oud, vanilla and woods are base notes and last the longest. A scent built mostly on citrus will always fade sooner, whatever its concentration.

Do all perfumes have exactly three notes?

No. Real formulas contain dozens of materials. The three listed notes are the ones you notice most at each stage, a simple map of a complex blend.
