The note, in its truest form, is not a singular scent but a highly concentrated, alcohol-free perfume oil, an embodiment of pure botanical essence, typically achieved through hydrodistillation. Its olfactive profile is profoundly rich, deep, and often viscous, delivering an immediate intensity that evolves slowly and gracefully on the skin. Depending on its source (e.g., rose, oud, sandalwood, jasmine), it can present as exquisitely floral, hauntingly woody, deeply resinous, warmly animalic, or delicately spicy. It possesses remarkable longevity, often lingering for days, with a projection that is typically intimate, creating a personal aura rather than a room-filling cloud. The texture on the skin is often oily, luxurious, and deeply hydrating, absorbing slowly. It typically behaves as a heart or base note, revealing layers of complexity over hours.
