It is a common misconception that sealed perfume has an indefinite shelf life. While oxygen and evaporation are the primary causes of perfume degradation, sealed perfumes are still susceptible to external factors such as light, heat, and humidity. Therefore, it is crucial to store sealed perfumes in a cool, dry, and dark place, away from direct sunlight or heat sources. Additionally, the quality of the perfume also plays a role in its longevity, with some cheaper brands more likely to spoil within a few years, even when stored properly. However, with adequate storage conditions, a well-sealed perfume can last for several years and sometimes even decades.

What You'll Learn
Sealed perfume can last for decades
Sealed perfume can indeed last for decades, provided it is stored correctly. The biggest threat to perfume is oxidation, which occurs when perfume is exposed to oxygen, light, heat, and humidity. This causes the chemical compounds that make up the scent to break down, resulting in a change in the fragrance that causes it to go bad.
To prevent oxidation, keep your perfume in its original packaging and bottle, tightly sealed, and stored in a cool, dry, and dark place away from direct sunlight or heat sources. The fridge or freezer is a good option, as long as it is not constantly being opened, which can cause temperature fluctuations. Another option is to wrap the bottle in aluminium foil and store it in a cupboard.
Additionally, avoid storing perfume next to other strong-smelling products, as perfumes can absorb other smells. Keep them away from bathrooms and showers, as humidity can also cause the perfume to break down.
While perfume does not have an expiration date, the scent may change over time, with some of the top notes disappearing or fading in potency. However, this does not mean that the perfume has gone bad, and it can still be safely used.
If you are concerned about the safety of using old perfume, it is recommended to spray a small amount on your wrist and wait for a day to see if there are any skin reactions before spraying it elsewhere.

Oxygen exposure causes perfume to spoil
Sealed perfume can indeed go bad, but it takes a long time. Generally, perfumes have a shelf life of around 30 months, or two to three years, but they can be preserved for decades if stored correctly.
To prevent oxidation, keep your perfume in its original bottle and store it in a cool, dry, and dark place. The fridge is a good option, but if the fridge door is constantly being opened, this may not be ideal. Wrapping the perfume in aluminium foil or storing it in the freezer are alternative solutions.
Perfumes with citrus notes are more prone to faster rates of oxidation, so these scents should be prioritised when it comes to storage. Additionally, the actual perfume formulation may impact how quickly the scent will spoil.

Keep sealed perfume in a cool, dark place
Keeping sealed perfume in a cool, dark place is essential to preserving its scent and preventing bacteria from growing. Ideally, perfumes should be stored at room temperature, away from heaters, windows, and direct sunlight.
A consistent environment will help preserve the fragrance for longer. The bedroom drawer or cupboard is a good option, as long as it is not too hot or cold, and the bathroom should be avoided due to the heat and humidity from showers, which can degrade the scent.
The original box is also a good place to store perfume, as it was made to hold the aromatic elixir within, and when paired with a closet or dark cupboard, you have a fail-safe method of essence endurance.
Additionally, it is important to note that perfume will stay pristine until it is opened. Introducing a bottle of fragrance to oxygen causes the scent inside to dilute and become oxidised, so keeping it sealed until use is best.

Humidity and heat can cause perfume to break down
Sealed perfumes can last for years, but they do expire eventually. Heat and humidity can cause perfume to break down, even if it is sealed. The ideal storage conditions for perfume are in a cool, dry, dark place, such as a cupboard or drawer.
Heat can cause the chemical bonds in perfume to break down, altering the scent or making it less powerful. This is true for perfume in a bottle and perfume that has been applied to the skin. Exposure to direct sunlight, even during winter, can impact the quality of a fragrance. The more frequently a perfume bottle is exposed to sunlight and heat, the faster its chemical bonds will break down.
High humidity can cause perfume to evaporate more quickly, making it less potent and shortening its lifespan. This is why it is not recommended to store perfume in bathrooms, as the steam from showers and baths can increase humidity.
To preserve the quality of your perfume, it is best to avoid exposing it to large temperature swings and extreme heat or cold.

Perfumes can absorb other smells
While perfume does expire, proper storage can extend its shelf life. For example, storing perfume in a cool place like a fridge or freezer can help slow down the oxidation process that causes the fragrance to expire. However, it is important to note that frequent decanting of fragrances into smaller bottles exposes the perfume to more oxygen, accelerating its expiration.
Perfumes are susceptible to absorbing other smells, which can alter their chemical makeup and cause them to expire sooner. To prevent this, it is advisable to store perfumes in their original bottles and keep them sealed when not in use. Additionally, storing them in a cool, dark place like a cupboard or drawer can help minimize exposure to oxygen and potential odour absorption.
The presence of oxygen accelerates the alteration of perfumes, so it is recommended to use the perfume consistently and avoid letting it sit half-empty. If you have multiple perfumes, rotating them can help manage oxygen exposure and slow down the expiration process.
Certain perfume formulations are more prone to oxidation and expiration. For example, citrus-based perfumes tend to oxidize faster, so storing them in the fridge or freezer is particularly beneficial. Additionally, cosmetic chemist Ginger King notes that perfumes can turn a darker brown colour when they go bad due to the oxidation of the oils they contain.
To summarize, perfumes can absorb other smells, and proper storage practices can help mitigate this issue and extend their shelf life. By minimizing oxygen exposure and maintaining consistent usage, you can enjoy your perfumes for longer before they expire.
