Why can't I smell my fragrance if there's still a little bit of liquid left?Updated 4 months ago

Our fragrances are designed with a special oil that effectively disperses the scent. Each fragrance has its own lifespan, but if you can no longer smell the fragrance after diffusing it for over 100 hours, what remains in the vial is just plain oil, without any fragrance. That's when you know it's time to replace it with a new vial for a fresh scent experience!
