O2
Fragrance notes
Character
O2 by Impulse opens with a sharp, almost aggressive citrus volley, lime and bergamot cutting through the air like a slice of cold, wet mint. The heart soon unfolds into something softer and more curious, a watery apple and water lily duet that feels less like a flower in a garden and more like the scent of a swimming pool at dawn, chlorinated and dewy. Musk anchors the base, but barely, a faint wisp that lets everything else evaporate quickly.
This is a fragrance built for a single moment, not a day. With a longevity barely scraping two hours and sillage that stays close to the skin, O2 is the olfactory equivalent of a half-sucked lemon drop, bright and tart, then gone. It feels synthetic in a charming, nostalgic way, like a body spray from a late-90s mall kiosk, but the rating suggests people adore it for exactly that reason. Who wouldn’t want a fleeting burst of spring mornings and summer afternoons, a clean, aquatic citrus that asks nothing of you but a smile? It suits anyone chasing a light, breezy refresh for gym bags, post-shower laziness, or a quick lift before a hot day. Those who need depth or staying power should look elsewhere, because this one fades before you’ve finished your first iced coffee.
