Creamy coconut water and clean aldehydes over soft musk, a little incense and warm sandalwood.
Byredo's 2025 Eau de Parfum, made by perfumer Jérôme Epinette and inspired by the easy joy of Brazil. It opens with coconut water and bright aldehydes, softens into musk, jasmine and a thread of incense, and dries down to sandalwood, cashmeran and amber. A clean, sunny skin scent rather than a beachy sweet coconut.
