The note unfolds with an immediate, dazzling effervescence, a vibrant burst that is at once tart and exquisitely juicy, yet possesses a nuanced sweetness distinct from a common Persian lime. It carries an almost bell-like clarity, bright and piercing without being harsh or metallic. There's a subtle, green-floral undertone, a whisper of crushed leaf alongside the sharp citrus, suggesting a more complex aromatic profile than a simple lemon or standard lime. Its texture is initially sharp and almost fizzy, then settles into a smoother, verdant acidity. Projection is typically strong and exhilarating upon application, a beacon of freshness that swiftly dissipates, marking it firmly as a top note. It lends an unmistakable sense of uplift and clarity, bright and invigorating, with moderate longevity for a citrus, often allowing its character to subtly intertwine with developing heart notes before gracefully fading.
