Does perfume expire?
Perfume does not last forever. Good storage slows the change, and a few signs tell you when a bottle has turned.

Perfume changes over time
Fragrance materials react with air, light, and heat. Over time, a perfume can lose its top notes, darken, or develop a sour or flat smell. Some materials can also change chemically when exposed to air. EU rules treat certain fragrance substances that become known allergens through air oxidation as equivalent to those allergens.
There is no single shelf life for perfume. It depends on the formula and how the bottle is kept.
What the label can tell you
Many products sold in the EU carry a period after opening (PAO) symbol: a small open jar with a number and "M", such as "24M". It shows how many months the maker says the product keeps after opening. Some products show a "best before" date instead. Batch codes identify production lots, but they are not a date you can read easily.
How to store perfume
Keep it cool.
Away from radiators, windows, and hot cars.
Keep it dark.
In its box, a drawer, or a cupboard. Direct sunlight speeds up change.
Keep it closed.
Replace the cap so less air gets in.
Keep it stable.
Avoid moving bottles between hot and cold places. A steamy bathroom is not ideal.
Keep it away from flames.
Most perfumes contain alcohol and are flammable. Keep them away from flames and heat, and out of reach of children.
Signs a perfume has turned
- The top smells sharp, sour, or like nail polish remover.
- The color has darkened noticeably.
- The scent seems flat or very different from how you remember it.
If you are unsure, compare it with a fresh tester. If it has turned, stop using it on skin.
Travel
Use a small travel atomizer and keep it in a cool part of your bag. Check current airline and airport rules for liquids before you fly.
