Every perfume changes as it wears. What you smell in the first minute is not what you smell after lunch. Those stages are called notes — top, middle (heart) and base — and once you understand them, choosing a fragrance (or a dupe) gets much easier.
What are fragrance notes?
A fragrance is a blend of ingredients that evaporate at different speeds. Light, small molecules evaporate first; heavy ones linger for hours. Perfumers group them into three layers, often drawn as a pyramid:
| Layer | When you smell it | Typical notes |
|---|---|---|
| Top notes | First 5–30 minutes | Citrus (bergamot, lemon, mandarin), fresh herbs, light fruits |
| Middle (heart) notes | About 30 minutes to 3–4 hours | Florals (rose, jasmine, orange blossom), spices (cinnamon, cardamom) |
| Base notes | From about an hour to the end of the day | Woods, vanilla, amber, musk, patchouli, oud, tonka |
1. Top notes: the first impression
Top notes are what you smell when you first spray. They're bright and fleeting — designed to grab attention, not to last. That's why a fragrance you "loved in the shop" can feel different an hour later.
Example: the grapefruit and marine opening of Lie 78 (Invictus-inspired), or the bergamot and blackcurrant opening of Lie 38 (Aventus-inspired).
2. Middle notes: the heart of the fragrance
Once the top notes fade, the heart takes over. This is the fragrance's real personality and the part people around you notice most during the day.
Example: the rose and rhubarb heart of Lie 108 (Delina-inspired), or the jasmine and orange blossom in Lie 30 (Black Opium-inspired).
3. Base notes: what lingers
Base notes are the heaviest molecules and the foundation of the scent. They're what you smell on your scarf the next morning, and they largely decide how long a fragrance lasts.
Example: the amberwood and cedar dry-down of Lie 40 (Baccarat Rouge 540-inspired), or the vanilla and tonka in Lie 37 (Tobacco Vanille-inspired).
How to test a fragrance properly
- Spray skin, not just paper. Skin warmth changes how notes develop.
- Wait. Judge it after 30 minutes and again after 3 hours, not in the first minute.
- Smell the dry-down. If you love the base, you'll love wearing it all day.
Why notes matter when choosing a dupe
A good dupe matches the whole pyramid, not just the opening. Plenty of cheap copies smell right for ten minutes and then collapse into something generic. When we develop a fragrance, the dry-down is where we spend the most time, because it's what you actually wear.
It's also why we're honest that dupes are close, not identical: some expensive natural materials (real ambergris, certain ouds and absolutes) are replaced with alternatives, and that usually shows up subtly in the heart or base.
Using notes to find your next fragrance

Frequently asked questions
Which notes last longest?
Base notes — woods, vanilla, amber, musk, patchouli and oud.
Why does a perfume smell different on me than on my friend?
Skin chemistry, skin dryness and temperature all change how notes evaporate.
Do top notes matter if they fade quickly?
Yes — they shape your first impression and set up the heart. But choose a fragrance for its dry-down.
