Our take

You spray Nº4 Neon and immediately the citrus trio of pomelo, yuzu and mandarin orange hits like a flash of highlighter across a clear morning sky. It’s sharp, electric, almost acidic, but the sweetness of mango and melon rushes in within minutes, softened by the green, slightly bitter edge of galbanum. This is not a contemplative fragrance; it’s a squirt of tropical neon light, the sort you’d see reflected off a pool at noon. The base of ozonic notes, solar accords and aldehydes keeps everything airborne and synthetic, like the heat shimmer above wet pavement. There is no hiding here.

The overall character is a single, vivid image: a plastic beach ball inflated with sunshine and left to bob on a chlorinated wave. It’s sweet and fresh, but the sweetness is candied fruit, not nectar, and the entire composition feels deliberately artificial in a way that works for a few hours. The longevity sits at 3.78, meaning it will evaporate before your afternoon coffee, and the sillage at 3.24 is a soft cloud that stays close after the initial burst. For a 2023 launch, the rating of 3.96 is fair: fun but fleeting.

This is a fragrance for the office worker who wants to feel like they’re on holiday while stuck at a desk, or for a sunny brunch where you want to smell like a splash of juice. It’s almost purely seasonal, summer and spring only, and strictly daytime wear. Skip it if you want something that lasts through dinner or has any woody, earthy anchor. It is a splash, not a story. Is a three-hour flash of citrus and melon worth the bottle? Only if you love to chase the light.
