The note of Body Heat is less a singular aroma and more a profound, enveloping olfactive sensation, a ghost of human presence. It presents as an intimately warm, soft, and slightly saline skin-musk, utterly clean yet imbued with an underlying, subliminal animalic warmth. Its texture is akin to cashmere or a perfectly worn cotton tee – soft, lived-in, and comforting. It possesses extremely low projection, existing as a true "skin scent" that merges seamlessly with the wearer's own chemistry, becoming an extension of their aura. Longevity is exceptional, often clinging to fabric and skin for days, evolving from a whisper of clean warmth to a deep, resonant musk. It functions almost exclusively as a foundational base note, an anchoring element that gives other notes a profound sense of human connection and lived-in comfort. It's not sharp or effervescent; rather, it is diffusive and enveloping, a warm hum rather than a distinct melody.
