A perfume is built like a musical chord, composed of Top, Heart (Middle), and Base notes that evolve throughout the day.
The initial scent you smell immediately upon spraying. Typically light, volatile, and fresh (citrus, bergamot, aquatic accords). Lasts 15 to 30 minutes.
The core character of the fragrance that emerges after top notes dissipate. Features florals, warm spices, herbs, or fruity accords. Lasts 3 to 5 hours.
The deep, long-lasting foundation that binds with your skin chemistry. Features rich woods, amber, vanilla, musk, and oud. Can last 8 to 24 hours.
