Is perfume flammable? Key indicators that your fragrance has expired
Many perfumes do not have a set expiration date. Some will die in less than a year, while others will live for up to ten years. A fragrance, on the other hand, has an average shelf life of three to five years. Perfumes with heavier base notes, according to experts, will last the longest.
It doesn’t last long. Can cologne go away? Is Perfume safe? Those are some of the things you might be thinking about as you keep adding perfume to your dresser. However, if you’ve had fragrance for a long time, you may have noticed that its strength has gone down, or that it has a weird smell.
So, can perfume go off? Is that true? There is no doubt about that. There are many things you can do to make it last longer. Not only that, but there are a lot of things that can affect how long a perfume lasts, like how well it’s made, how it’s stored, and how it’s used.
Here, we will try to help you understand how long perfume lasts and how to tell if your perfume has gone bad, as well as how to store it.
You can tell if your perfume has expired by looking for a few key indicators, such as scent – does it smell different, appearance – has the colour changed, and date – some perfumes may have an expiry date. Test How it smells – smelling your perfume is one of the most obvious ways to tell if it has gone bad.
How to Extend the Life of Your Perfume
- Keep Perfume away from direct sunlight.
- Keep Perfume away from heat and place it in a closed cupboard.
- Keep Perfume in a Cool Place
- Continue to use it until the bottle is empty.
Three Simple Ways to Tell If Your Perfume Is Expired
You can detect whether your perfume has expired by examining several important indicators: scent – does it smell different? appearance – has the colour changed? and date – certain perfumes have an expiration date.
- Test How it smells – one of the simplest methods to determine whether or not your perfume has gone bad is to smell it. Certain scents may contain fats such as vegetable oils and will eventually degrade. If your fragrance is fat-free, it will stay longer. If you find that the aroma smells much different than when you purchased it, or if it acquires undertones of vinegar or other more chemical notes, it’s time to replace it.
- Consider the appearance – a good technique to evaluate your perfume is to consider the colour. Perfumes whose colour darkens or turns opaque over time are an indication of ageing. Often, perfumes with a high alcohol content evaporate, leaving the essential oils much more concentrated. If you observe a decrease in the amount of perfume in the bottle and are certain you haven’t been using it, this is a good indication that it is about to expire.
- Examine the expiration date – frequently, a perfume producer will print an expiration date on the container. This may be a batch code or a PAO (Period After Opening) number. These are often located on the bottom of the perfume bottle or printed on the box in which the perfume is packaged.
How to Store Perfume
Properly storing your perfume can help to keep it in good condition for as long as possible. Temperature and humidity fluctuations, as with most things, can wreak havoc on the delicate chemistry contained within the bottle. As a result, you should keep your perfume in rooms with consistent temperatures, such as bedrooms and dressers, and resist the urge to do so in the shower.
Consider the placement of your dresser and makeup mirror, if possible. Additionally, avoid storing your perfume in direct sunlight, as heat degrades the chemical structure of the perfume, reducing its strength. Furthermore, avoid chilling your perfume in the refrigerator for a refreshing day, as bringing it back to room temperature may be harmful.
Perfume should be kept in a cool, dry, and dark place, such as a bedside drawer or closet. It is advised to keep the perfume in its original container because air exposure may alter the chemical equilibrium. Furthermore, it can hasten the evaporation of the alcohol contained within, causing the aroma to fade faster. It can be difficult to tell whether a perfume has expired or not.
If your perfume is more than two and a half years old, it should be tested for expiration. However, if your perfume smells good and retains its original colour and consistency, it is safe to use. Certain high-quality scents can even last for years if cared for properly.
How Long Does Perfume Last If It Isn’t Opened?
This is a question you may ask yourself every time you receive a new bottle of perfume, and to be honest, it’s difficult to tell with no expiration date on the bottle.
An unopened bottle of perfume can last several years depending on how it is stored, according to Givaudan perfumer Jacques Huclier, who has created fragrances for brands such as Gucci, Thierry Mugler, and Hugo Boss. “I recently had the opportunity to evaluate a never-opened bottle of perfume from the 1980s, and it was as good as new,” Huclier says. “There are no hard and fast rules; each fragrance has a different shelf life.”
That being said, it’s always a good idea to finish one bottle before beginning to use another.
How Can You Tell if a Perfume Has Expired?
When a perfume has expired, the smell becomes slightly sour, especially as the top notes oxidise. This may have a faint metallic odour.
“Oxygen in the air can change some of the molecules in a fragrance over time,” Huclier says. “Top notes, such as citrus, fruits, aromatics, green notes, and patchouli, are generally the most prone to oxidation. Discoloration [of the juice] is another sign that perfume has expired. The good news is that fragrances have a longer shelf life than ever before, thanks to the use of stabilisers and UV filters, which make the molecules less susceptible to oxidation.”
The best way to determine if a perfume has expired is to spray it on a piece of paper and smell for any off-notes. This method also ensures that you don’t have the scent on you all day, which is especially important if the scent has expired.
“You can also see if the colour or shade of the juice itself has changed; if it looks darker or has a yellow tint, it usually means the fragrance has oxidised,” Gavarry says.

Is it Possible to Extend the Shelf Life of Perfume?
Keep perfumes away from any source of heat. A perfume’s main enemies are oxygen, light, and heat. “It’s best to store a perfume in a cool dark place, away from heat and daylight, as UV light can harm the fragrance and breakdown its formula,” says Gabriela Chelariu, a senior perfumer at Firmenich who has created perfumes for Nest, Gwen Stefani, JLo, and Abercrombie & Fitch. “The best climate and storage space for a fragrance is in the refrigerator.”
Some perfumes also have a longer shelf life than others.
“In general, oriental perfumes with spicy, wood, and vanilla notes have a longer shelf life than other perfumes in different olfactive categories,” Chelariu says. “The natural ingredients in these formulas are more potent and structurally stable in nature.” Huclier adds that because they are less fragile, these rich base notes are less volatile and have a higher resistance to oxidation.
What Happens If You Reapply a Perfume That Has Expired?
There isn’t much to say about it except that it smells a little off.
“It’s unusual for a person to have an adverse reaction to expired perfume,” Chelariu says. “During the life of every perfume, there is a natural process of oxidation that occurs, and this can generate compounds in the juice that are irritating to certain skin types.”
