Déjà Vu room spray (& scent overall) is, well, something you’ll never forget😄 We’ve yet to try it in the diffuser but will get there bc the room spray is delightful. The notes creating this fragrance blend expertly together. Each has their time in the sun (your nose). Particular hats off to Aroma360 for using Oud not only as a base but anywhere as a note bc if you don’t know, oils like Oud Wood or Opopanax are wildly expensive. Top quality like Aroma360 uses, when bought as oils in TEENY TINY drams (bottle is less than an inch!), cost well into the 100s. An all organic, top essential oil place I know (& are 100% legit) has all size OIL bottles but even the tiny dram size is near or over $500! So, if you didn’t know the pure decadent, luxurious fragrances that are in these blends, like Déjà Vu, if you like the scent, you’re getting a SUPER deal bc Aroma360 chose to use some of the most expensive oils in the world- and don’t take it out on us! Déjà Vu as a room spray, lingers well and holds its scent to enjoy for hours. Bc I love Narcissus so much, my nose is able to distinguish that scent from its “scent siblings/notes” in the delightfully crafted blend. But, each note has its turn to peak. I also use it as a wearable fragrance (pls do not do so w undiluted scents until you do a scent test patch on skin or otherwise dilute it; my skin is tough & only feels warm if hit by cinnamon or mints; everyone is different so use caution here pls), while I’m happily married, when I’m out…
