How long is the shelf life of perfume

I believe that many people in life like to collect perfume, because perfume is not only beautiful in appearance, but also has great collection value. However, the shelf life of perfume varies according to the variety. Some perfumes may have a shelf life of no more than one year, some are around 3-5 years, and some antique perfumes are around ten years.

meeting. But the main reason is the sunlight and temperature, not the fault of time.

If you find two bottles of the same perfume, put one on the windowsill to dry in the sun, and the other at the bottom of the box, after two weeks you will find that the smell of the former has deteriorated.

So I usually don’t recommend putting perfume on the center console of your car. After being exposed to the sun and high temperatures for several months, some smells become really unbearable.

This has little to do with whether it is opened or not. The spray-type perfume bottle itself has a certain degree of sealing, and even if it is opened, it will not be exposed to the air over a large area. But even if the perfume is unopened, there is still air in the bottle. So there is no need to worry about whether it is opened or not, there is not much difference.

Keep in a cool place, away from light and avoid shaking.

Perfume has no fixed shelf life. According to the above storage conditions, three to five years will not be a problem.

If it's ten years...it depends on the quality of the perfume. For some perfumes, the top notes have already deteriorated but it does not affect the middle and base notes at all. For some perfumes, the whole thing has deteriorated to the point where it is unscentable.

There is also a saying that "the scent becomes mellower with the passage of time", but most of them are early perfumes (such as Guerlain's original Madame Butterfly), the raw materials are expensive and sophisticated, and some fragrance raw materials are even banned now.

If you are not a vintage perfume player but just a perfume consumer, there is no need to keep it for ten years. Most modern perfumes are of average quality and have no collection value. What's more, a bottle of perfume may no longer be popular after ten years.

I keep perfumes that I rarely use in my closet to add a little fragrance to my clothes.

Why do perfumes sold at domestic counters have production dates or expiration dates marked on them?

This is the requirement of our country's health quarantine department. Cosmetics and perfumes must be labeled. Foreign counters do not have this requirement.

Why do some perfume packages have a sign saying "Recommend using up within xx days after opening"?

This is a recommendation, not a requirement.
