Some industry experts say that perfume should be replaced every year, but properly stored, perfumes should last much longer. Most perfumes will keep several years, some will keep many more years than that.

To store perfume properly, keep it away from heat and light. A dark closet or a covered box is best. Also avoid direct exposure to air. Splash bottles, which expose the fragrance to air every time they are opened, are problematic. Consider decanting into a smaller atomizer for regular use. If you apply perfume directly from a bottle stopper, wipe the stopper with a clean, lint free cloth before replacing it in the bottle.
