A. How long a perfume can be used depends on the product and its storage conditions; there is no single number of years that applies to every perfume. Start by checking the product label and the manufacturer’s guidance.
Where you store a perfume and how you handle its container matter if you want to limit changes in its scent. Chanel’s official FAQ also recommends avoiding heat, air, and light and keeping the cap tightly closed. Depending on storage, you may be able to enjoy a fragrance for a long time, but the fact that it still has a scent does not, on its own, tell you whether it remains suitable for use on skin. If your perfume is old or you are concerned about changes in its condition, check with the manufacturer.
When storing perfume at home, keep these two points in mind.
①Store it away from light and high temperatures, in a place with little temperature fluctuation. A drawer or closet out of direct sunlight and away from heaters or other heat sources may be suitable.
②Keep the container properly closed. Close capped bottles securely, and if you keep one in a bright place, shield it from light with its original box or something similar.
What, then, should we make of the advice to “store perfume at 12°C”? The Osmothèque’s official description of its perfume archive combines storage in darkness at a constant 12°C under an argon atmosphere with regular assessments by perfumers. Argon is a gas used to limit the perfume’s contact with air. This is specialist management for preserving fragrances as cultural records, not a claim that keeping perfume at 12°C at home will achieve the same preservation.
In a 2011 official newsletter, founder Jean Kerléo describes examples of perfumes preserved for twenty years or more using this method. At the same time, Kerléo says that they cannot be preserved forever. These examples cannot be used to make a blanket judgment about a perfume’s usable life at home or the safety of applying an old perfume to skin.
Perfume is alive. It evolves, changes, and shifts. But its worst enemies are light and heat. My advice is very simple: keep your perfume away from light and heat.

Among the places around your home, be careful with the following, which are particularly exposed to light, high temperatures, or temperature changes.
Bathrooms and washrooms where steam and heat build up, and windowsills exposed to direct sunlight
