What Is the Perfume Pyramid ? A Guide to Fragrance Structure & Scent Progression
Why does your perfume smell different an hour after you apply it?
The answer lies in the perfume pyramid—the structure behind how a fragrance develops over time. From the bright, fleeting top notes to the deep, long-lasting base notes, this model helps you understand scent evolution, improve your perfume choices, and even craft your own blends.
What Is the Perfume Pyramid?
The perfume pyramid is a foundational model used in perfumery to describe how fragrances unfold in three sequential stages:
- Top Notes (head): First impression, light and quick to evaporate
- Middle Notes (heart): Main body of the scent
- Base Notes (foundation): Deep, long-lasting anchor
These layers are structured based on evaporation rate, helping perfumers balance freshness, longevity, and scent complexity.
Breakdown of the Pyramid: Top, Middle, and Base Notes
| Layer | Description | Duration | Examples |
|---|---|---|---|
| Top Notes | Lightest, first to evaporate | 5–30 minutes | Bergamot, lemon, mint |
| Middle Notes | Heart of the fragrance | 1–4 hours | Rose, jasmine, cinnamon |
| Base Notes | Deepest, longest lasting | 4–12+ hours | Patchouli, vanilla, sandalwood |

Visualize the fragrance journey:
Top (Peak): Fresh, light, short-lived (e.g., citrus, herbs)
Middle (Heart): Rich, character-defining (e.g., florals, spices)
Base (Foundation): Deep, memorable, long-lasting (e.g., woods, resins)
Scent Progression Example: How a Perfume Evolves Over Time
- 🕒 0–15 minutes: Lemon and bergamot sparkle and fade quickly (Top)
- 🕒 15–60 minutes: Jasmine and rose dominate the heart (Middle)
- 🕒 1–8+ hours: Patchouli and amber emerge and linger on skin (Base)
Each stage contributes to the full sensory experience.
