How long your perfume can be stored depends on a variety of factors, including the scent's chemical composition, the quality of the fragrance, and how it is stored. While some perfumes will begin to expire in less than a year, others can last upwards of 10 years or even several decades if stored correctly. Proper storage involves keeping the fragrance in a cool, dry, and dark place, such as a bedroom drawer or closet, and avoiding exposure to light, heat, and humidity. Additionally, it is recommended to keep the perfume in its original container to prevent oxidation and evaporation of the alcohol inside. Well-respected brand names and perfumes with heavier base notes tend to have longer shelf lives.

Opened vs. unopened
Perfumes typically last for several years, but once opened, a bottle should last anywhere between three months and three years, depending on the scent's construction, packaging, and storage conditions. Most fragrance manufacturers recommend disposing of the bottle after one to three years, but it is sometimes okay to continue using it for up to five years. Opened perfumes are exposed to oxygen, which can alter the molecules of the fragrance and affect the overall scent. Over time, the scent may become oxidised, sour, acidic, metallic, or develop notes of plastic. Opened perfumes can also start to stain clothes and may cause skin irritation or allergic reactions.
To prolong the life of an opened perfume, it should be stored in a cool, dry place, away from heat and sunlight, and kept in its original bottle. The fridge or freezer is a good option, as long as the temperature remains consistent. Wrapping the bottle in aluminium foil can also help protect the perfume from light exposure.
Unopened perfumes can last for many years, sometimes even decades, if stored correctly. The ideal storage conditions for unopened perfumes are similar to those for opened perfumes: a cool, dry, and dark place, away from direct sunlight. The expiration date of luxurious and expensive perfumes tends to be longer than those of mass-market and ordinary brands. As a rule of thumb, perfume should be used within three years of the manufacture date. However, some perfumes, especially from well-respected brands, may not have a hard-and-fast expiration date and can last upwards of ten years.
To determine if an unopened perfume has expired, you can evaluate its scent, appearance, and any expiration dates or batch codes on the packaging. If the fragrance has changed, or the liquid has become darker or more opaque, it may be a sign that the perfume has expired.

Storing in the fridge
Storing perfume in the fridge is a popular suggestion for preserving the fragrance for longer. However, opinions vary on whether this is beneficial or detrimental to the perfume.
Some sources claim that the cold temperature of a fridge can 'shock' fragrances, breaking down scent molecules and reducing the overall depth of the scent. This can cause a decrease in the intensity of the perfume. Therefore, it is generally advised that unless you live in an extremely hot climate, there is no need to store your perfume in the fridge.
On the other hand, some people argue that storing perfume in a cool, dark place like a fridge can help slow down the oxidation process and protect the volatile fragrance compounds from damage. This can extend the life of the perfume by preventing the breakdown and oxidation of scent molecules, which can be caused by exposure to light, heat, and humidity.
One user reported that storing their perfume in the fridge helped them get more than eight hours out of a fragrance that was not performing well. Additionally, keeping perfume in the fridge can provide a refreshing and calming sensation when applied to the skin, especially during hot summer days.
While storing perfume in the fridge may have some benefits, it is important to consider the potential for drastic temperature changes, especially if using a regular refrigerator. Taking the perfume in and out of the fridge can cause condensation on the bottle, which may be undesirable for some.
Overall, while fridge storage may be beneficial in very hot climates or for fragrances that are not performing well, it is generally recommended to store perfume in a cool, dark, and dry place, such as a closet or cupboard, to maintain its longevity and prevent drastic temperature changes.

Exposure to light
Although it may be aesthetically pleasing to place perfume bottles on a windowsill, this is the worst place to store them if you want to preserve their integrity. Sunlight, in particular, can cause perfumes to degrade. Standard window glass blocks out nearly all UVB rays, but about 75% of UVA rays get through. If the bottle is clear glass, about 56% of UVA rays will reach the fragrance. However, if you add a shade to the window, the remaining, more scattered sunlight loses energy, and it is not strong enough to penetrate the perfume bottle. If you store the fragrances on a shelf further away from the scattered light, the UV rays become even weaker.
Light from a lightbulb may also damage fragrances over time, although the heat generated by the lightbulb is likely to be more damaging than the light itself. One source suggests that unless the light is shining directly on the fragrances for about six hours a night, there is no need to worry.
To preserve your perfume, it is best to store it in a cool, dark, and dry place, such as a cupboard or a refrigerator. Keeping the perfume in its original packaging or a full-size bottle will also help to protect it from external aggressors that could alter its scent.

Oxidation
To prevent oxidation, it is crucial to store perfume in a way that minimizes its contact with oxygen. This includes keeping it in its original bottle, as decanting the fragrance into smaller containers increases its exposure to oxygen. Storing perfume in a cool, dark, and dry place, such as a cupboard or a refrigerator, can also slow down the oxidation process. The refrigerator is an ideal storage location, especially for citrus-based scents, as it maintains a consistent temperature and blocks out light. However, frequent opening of the fridge door can negate its benefits. Wrapping the perfume bottle in aluminium foil or storing it in the freezer are alternative options.
Additionally, the perfume's packaging plays a vital role in protecting the fragrance from oxidation. The original packaging is designed to safeguard the perfume from external factors that can alter its scent. It is crucial to keep the perfume in its original packaging until use to ensure maximum protection.
While oxidation primarily affects the scent of the perfume, it can also cause other changes. One notable alteration is the darkening of the perfume's colour, which is a direct result of oxidation and light exposure. However, it is important to note that oxidized perfume can be safely used on the skin without any harmful effects.
Although oxidation in perfumes is typically associated with negative consequences, a recent study introduced the concept of the "human oxidation field." This term describes how the oils on our skin, when exposed to ozone, can generate hydroxyl radicals. Interestingly, the study found that applying perfume can lower the concentration of these hydroxyl radicals by 86%. While the implications of this discovery are still being explored, it highlights a potential positive impact of oxidation in perfumes.

Expiry dates
Perfumes do not have a hard-and-fast expiration date. Their longevity depends on the scent's chemical composition and how the perfume is stored. Some perfumes will begin to expire in less than a year, while others will last upwards of 10 years. If stored correctly and untouched, a perfume can even last for decades.
The oxidation that occurs when exposed to air can alter the molecules of the fragrance, affecting its overall scent. Therefore, it is best to keep the perfume in its original container and away from light, heat, and humidity. A cool, dry, and dark place such as a bedroom drawer or closet is ideal for storage. The fridge is also a good option, but constant lighting inside the fridge can spoil the fragrance.
Unopened bottles stored in a cool, dark, dry place can last for years, depending on the perfume and storage conditions. An opened bottle of perfume can last anywhere between three months to three years, depending on the scent's construction, packaging, and storage conditions.
There are some signs that your perfume could be nearing its expiration date. One of the most obvious ways to tell is to smell it. If the scent smells vastly different from when you bought it or develops hints of vinegar or other chemical notes, it is probably expiring. Another way to test is to look at the colour. Perfumes that become darker or develop opacity over time are signs of aging. If there is less perfume in the bottle and you're sure you haven't been using it, this is also a sign of expiration.
