Storage: The preservation of your perfume’s fragrance and/or longevity depends a lot on where and how you store it.

Fragrance Family: The shelf life of a perfume is also affected by the type of scent: is it a fresh scent? Is there any floral scent in it? Does it have a woody scent? Does it have an oriental scent?

Storage time: As long as they can be sprayed on the body or clothing, perfumes have a shelf life. The sweet spot usually lasts three to five years, however, some last only a few short months in a year, and others last for a decade. This factor, in addition to preservation, has a significant impact on the longevity of the scent.

Oil concentration: Colognes with a larger percentage of fragrance oils usually last much longer than those with a smaller percentage of aromatic ingredients. Find a way to determine the concentration level of the perfume. Most scents typically fall into one of the following categories for fragrance oil concentration by volume or percentage:

  • 20%-50% aromatic chemicals are present in perfume extracts.

  • Eau de toilette: 5% to 20% aromatics.
  • Eau de cologne: 2% to 5% aromatics.

Notes at the facility: Perfume shelf life is preserved by base notes; note the stronger the base, the longer the shelf life. Because of this, oriental perfumes generally last longer and improve with age, in contrast to perfumes from other scent families, which tend to fade away faster.

Checking the Expiry Date

How do I know if my perfume is expired? By looking at the expiration date on the bottle or other packaging, you can also determine if your perfume has run out of time. The Best Before Date and the Expiration Date are two different dates (the best time frame in which your perfume should be used). Look for the expiration date on the packaging’s surface or beneath it. The Batch Number or Period After Opening is the ideal place to look for the expiration date (aka PAO).

  • Batch Number:  the letters of the alphabet are frequently included in this number count, which falls between the ranges of 3 and 12. These batch numbers are often put on the packaging during the distribution of the fragrances, and even while they are used as a standard for quality control, they also reveal the date and location of a perfume’s production.
  • Period Following Opening, or PAO: This is represented graphically on the package as a cylindrical container with a number on it that has already been opened. This number, which is typically written next to the letter M for months, designates how long after opening your perfume you should use it. This is only an example, but if you see 20M on the jar it signifies that you should only use your perfume for 20 months (1 year, 8 months); again, this is just an example. It is advised to use the product for 30 months (30M).
