Scent Journey

1
Opening 0-30 min

The first 30 minutes are a dazzling explosion of citrus—pomelo and yuzu, sharp and juicy, with a hint of mandarin sweetness. The aldehydes add a sparkling, effervescent quality, making the opening feel like a glass of prosecco on a hot afternoon. The citrus is not harsh but rather luminous, with a slight bitter edge from the pomelo that prevents it from becoming too saccharine.

2
Heart 1-2 hrs

As the citrus begins to settle, the heart reveals a tropical softness: melon and mango lend a creamy, slightly honeyed sweetness, while galbanum introduces a green, resinous undertone that grounds the fruitiness. This phase is where the fragrance becomes more intimate, with the aquatic and ozonic accords emerging to create a sense of coolness and space. The sweetness is balanced, never cloying, and the overall impression is of a sun-kissed, relaxed vibe.

3
Drydown 4+ hrs

Hours later, the base notes take over: ozonic and solar notes create a warm, mineral-like aura that feels like sun-warmed skin. The aldehydes reappear, giving a clean, slightly powdery finish. The fragrance becomes softer, closer to the skin, yet still perceptible. It's a drydown that is both comforting and refreshing, leaving a trail of sheer cleanliness and subtle sweetness.
