The note of steam is less a traditional scent and more an ephemeral, textural impression; a shimmering, transparent veil that carries and amplifies other aromas. It opens with an initial rush of humid warmth, a sensation of moist air that is almost mineralic, faintly metallic, and incredibly clean, like fresh rain on hot pavement or the first breath of air from a just-opened dishwasher. It presents as an elusive, weightless current, a diffusing agent that softens sharp edges and lends a dewy, almost effervescent quality to a composition. Its intensity is subtle yet pervasive, creating an enveloping aura rather than a singular focal point. It has virtually no inherent evolution, but its presence dramatically alters the perceived evolution of surrounding notes, making them bloom with a newfound dewy freshness. Projection is gentle, often intimate, creating a 'second skin' effect of warmth and purity. Longevity is tied to the notes it elevates; on its own, it is fleeting, designed to create a momentary impression of clarity and diffusion. It functions predominantly as a top-to-heart note, dissolving into the composition like mist at dawn.
