What You'll Learn
Check the scent for vinegar or chemical notes
One of the most obvious ways to tell if your cologne has gone bad is to test its scent. If the cologne smells of vinegar or has developed other more chemical notes, it has likely expired. This is because some perfumes may contain fats such as vegetable oils, which are known to expire over time.
If you notice a significant change in the concentration of the original scent, it might be expired. It is also likely to have expired if the scent is significantly different from the one you started with.
To test the scent, spray the cologne once or twice on your hand and wait for it to dry. Then, bring your hand close to your nose and smell it. If you can't smell the cologne at arm's length, move your hand in small increments closer to your nose until you detect the scent.
Additionally, you can also check for other signs of expiration such as changes in appearance (darker colour or increased opacity) and the expiration date on the packaging.

Check the colour for opacity or darkness
One of the ways to determine if your cologne has gone bad is to check its colour for opacity or darkness. If you notice that the cologne has become darker or more opaque over time, it is likely that it has gone bad. This is a sign of oxidation and indicates that the fragrance is aging.
Additionally, if you notice that the cologne has evaporated and there is less liquid in the bottle than before, this could be another indication that the cologne is expiring. This is often the case with perfumes or colognes that have a high concentration of alcohol. The alcohol can evaporate over time, leaving behind a more concentrated mixture of essential oils.
It is important to regularly check the colour and opacity of your cologne, especially if it is older or has been stored for a long time. This will help ensure that the cologne is still safe to use and has not deteriorated. Checking the colour can be a quick and effective way to assess the condition of your cologne without having to open and smell it.
However, it is worth noting that some colognes may naturally change colour over time, especially those with heavy base notes such as woody, mossy, or earthy scents. These colognes tend to get better with age, like a fine wine, and the change in colour may not always indicate that the cologne has gone bad. Therefore, it is essential to consider other factors such as scent, expiration dates, and storage conditions to make a more accurate determination.

Check the packaging for an expiry date
Checking the packaging for an expiry date is a crucial step in determining whether your cologne has gone bad. While colognes and perfumes typically have a long shelf life, ranging from one to ten years, it's important to be aware of their expiration dates to ensure their potency and avoid any potential skin irritation or allergic reactions.
Expiry dates on cologne packaging can take the form of batch codes or PAO (Period After Opening) numbers. These are usually found on the bottom of the cologne bottle or printed on the box it came in. The PAO number specifically indicates the number of months the product will last once opened.
If you're unsure about the expiry date, it's best to refer to the batch code on the underside of the cologne bottle. You can contact the brand or manufacturer to inquire about the product's expiration date based on the batch code. This way, you can be certain about the cologne's shelf life and whether it's safe to continue using it.
In addition to checking the expiry date, it's important to consider the storage conditions. Proper storage plays a significant role in prolonging the life of your cologne. It's recommended to keep cologne in a cool, dry, and dark place, such as a bedroom drawer or closet. Storing it in its original container can also help maintain its chemical balance and slow down the evaporation of alcohol, resulting in a longer-lasting fragrance.
By paying attention to both the expiry date and storage conditions, you can make an informed decision about your cologne's freshness and effectiveness.

Check for skin irritation
Skin irritation is a sign that your cologne may have gone bad. If you experience redness, bumps, or allergic reactions on your skin after applying the cologne, it is likely that the cologne has expired and should be discarded.
To check for skin irritation, apply a small amount of the cologne to your skin and wait for a few minutes to observe any reaction. If you notice any redness, bumps, or other irritation, wash the area with mild soap and water to remove the cologne. You can also refer to the label to check for any ingredients that you may be allergic to or contact the brand for more information.
It is important to note that even if you have used the cologne previously without any issues, it can still cause skin irritation if it has expired. The expiration of cologne can depend on various factors such as the quality, scent family, and storage conditions. Therefore, it is recommended to test the cologne on a small area of skin before each use, especially if it is more than a couple of years old.
In addition to skin irritation, other signs of expired cologne include a change in scent, appearance, and the presence of an expiration date. If the cologne smells different, has a vinegar-like odour, or a significant change in concentration, it is likely expired. Moreover, if the colour of the cologne has darkened or become opaque, it may be a sign of oxidation and should be discarded. Checking the expiration date on the packaging, usually in the form of a batch code or PAO (Period After Opening) number, can also help determine if the cologne is still safe to use.

Store in a cool, dry, dark place
Cologne and perfume can definitely go bad, but there are ways to extend their lifespan. The quality, scent family, and how the fragrance is stored can have a major impact on how long it lasts.
One of the best ways to store cologne is to keep it in a cool, dry, dark place. Cologne is best suited to rooms with stable conditions and consistent temperatures, away from sunlight and humidity. A bedroom drawer or closet is ideal. Keeping cologne in its original container is also recommended, as exposure to air can upset the chemical balance and cause the fragrance to expire faster.
It's also worth noting that the more oxygen in the bottle, the quicker the scent will develop, so it's not a good idea to keep a bottle for a special occasion years down the line.
Other ways to store cologne include keeping it in its box (to filter out sunlight) and in the fridge, which maintains a stable and cold temperature.
