MOLECULAR ARCHITECTURE

THE FRAGRANCE PYRAMID

LAYER 01 / VOLATILE

TOP NOTES

Citrus, aldehydes, light herbs. Molecular weight: 100–200 Da. Vapor pressure: high. Duration: 15–30 minutes. The first impression, and the most deceptive layer.

Common: bergamot, lemon, grapefruit
LAYER 02 / SEMI-VOLATILE

HEART NOTES

Florals, spices, resins. Molecular weight: 200–350 Da. Duration: 2–4 hours. The true character of the fragrance: what it smells like after the top notes clear.

Common: lavender, pepper, geranium
LAYER 03 / FIXED

BASE NOTES

Musks, woods, resins, ambers. Molecular weight: 350+ Da. Very low vapor pressure. Duration: 8–12+ hours. These molecules bind to skin proteins for exceptional longevity.

Common: sandalwood, vetiver, musk
