Fragrances are a highly personal luxury, with people often developing a signature scent that becomes a part of their identity. However, fragrances can change over time, and several factors determine how long a perfume will last. The quality of the perfume, its chemical composition, and how it is stored all play a role in its longevity. While some perfumes can last upwards of 10 years, others may expire within a year. Exposure to air, temperature changes, and oxidation can all alter a fragrance's scent and potency, and even make it go bad. Additionally, the olfactory system's connection to the brain means that our perception of a fragrance can change over time as we pick up on different notes and associate the scent with memories and experiences.

What You'll Learn
Fragrances smell different to different people
The scent of a perfume is contingent on its chemical composition and how it is stored. However, the same perfume can smell different to different people.
One of the reasons why fragrances smell different on different people is because of the pH level of their skin. The pH level is a measure of the acid or base level of the skin environment. Skin that is either too acidic or too basic can cause a perfume to break down. Dry skin absorbs more fragrance, and oily skin retains the smell of top notes. The fragrance will react differently based on the individual's skin condition and its acidity.
The body's natural odour and temperature can also alter how the perfume wears on the body. When we smell a perfume on us, we are smelling a blended mixture of that perfume and our own body scent.
The activities we do while wearing a fragrance can also impact how it smells. For instance, drinking alcohol or eating garlic-heavy foods might give your skin an alcoholic or garlicky scent.
Additionally, our perception of a fragrance can change over time as we get used to it or go nose blind to certain notes, causing us to pick up on other notes that we didn't smell as much before.

Fragrances smell different over time
Firstly, individual body chemistry plays a significant role in how a fragrance smells over time. Each person's skin chemistry is unique, and factors such as pH levels, skin oils, and hormones can affect how a perfume interacts with the skin. For example, someone with oily skin might find that the middle or "heart" notes of a fragrance dominate, while someone with dry skin might experience the base notes more strongly. Additionally, external factors such as body wash, laundry detergent, or fabric softener can interact with a perfume, altering its scent.
Secondly, oxidation can cause fragrances to smell different over time. Similar to how alcohol oxidizes and changes flavour over time due to increased exposure to oxygen, fragrances, which also contain alcohol, can undergo chemical changes that alter their scent. The more surface area a fragrance has to interact with oxygen, the faster it will oxidize, potentially changing its smell.
Lastly, the way a fragrance is stored can impact its scent over time. Heat, light, and exposure to air can break down the chemical compounds in perfumes, causing them to smell different or expire faster. Therefore, it is recommended to store perfumes in a cool, dry, and dark place, such as a bedroom drawer or closet, to maintain their original scent for as long as possible.
It is worth noting that fragrances do not have a definitive expiration date, and their lifespan can vary significantly. Some perfumes may start to expire in less than a year, while others can last upwards of 10 years. Additionally, the quality of the fragrance and how it is cared for can impact its longevity.
Overall, it is not uncommon for fragrances to smell different over time due to a combination of factors related to individual body chemistry, oxidation, and storage methods.

Fragrances can expire
The most obvious way to tell if a perfume has gone bad is to test its scent. Some perfumes may contain vegetable oils, which are known to expire over time. If a perfume smells like vinegar or has a significantly different concentration from the original scent, it has likely expired. Additionally, exposure to heat, oxygen, and light can break down perfumes and cause them to expire faster. Therefore, it is recommended to store perfumes in a cool, dry, and dark place, such as a bedroom drawer or closet, and in their original containers to prevent exposure to air.
The potency of a fragrance can also lessen over time, or it may start to smell different. This could be due to oxidation, or it could be that, each time you wear a scent, you are picking up on different facets that you didn't sense before. Additionally, the activities you engage in while wearing a fragrance can impact how it smells in the future.
To extend the lifespan of a fragrance, it is important to store it properly, layer scents strategically, and avoid muddling conflicting scents together.

The olfactory system impacts how fragrances smell
The olfactory system, with its connections to the hippocampus, thalamus, and amygdala, plays a crucial role in how we perceive fragrances. Our sense of smell is highly subjective and influenced by various factors, including our memories, emotions, and individual biology.
When we first encounter a fragrance, our olfactory system processes the scent through the olfactory bulb, which sends signals to the brain. This initial impression is often influenced by our expectations and the context in which we encounter the fragrance. For example, a fragrance might smell appealing in a store but less so once we bring it home. This is because our olfactory system is constantly learning and adapting, picking up on different notes and nuances with each exposure.
Over time, our perception of a fragrance can change due to a phenomenon known as "nose blindness," where we become less sensitive to certain notes and start to notice others. Additionally, oxidation can alter the chemical composition of a fragrance, resulting in a different scent. This process occurs as the fragrance interacts with oxygen when exposed to air or when there is more space in the bottle after usage.
The olfactory system's connection to memory is also significant. Fragrances can evoke powerful memories and emotions, influencing our perception of a scent. For example, a fragrance might remind us of a particular person or event, enhancing our enjoyment of it. Conversely, if a fragrance is associated with a negative memory, it may be less appealing.
Furthermore, individual biology plays a role in how we perceive fragrances. Our genetic makeup influences the sensitivity of our olfactory receptors, which can vary from person to person. This means that people may have different thresholds for detecting certain scents, and some may be more or less sensitive to specific fragrances.
In summary, the olfactory system's complex interplay with our brains, memories, emotions, and biology shapes how we perceive fragrances. This subjective nature of scent means that the same fragrance can evoke different responses in different people, and even an individual's perception of a scent can evolve over time.

Storing fragrances in a cool, dry, dark place makes them last longer
Fragrances are delicate and can easily break down, causing the scent to change or disappear. Heat breaks down perfumes, so storing them in a cool place is essential. However, it is important to avoid temperature fluctuations, as these can be just as damaging as heat. Aim for a consistent temperature of around 60 degrees Fahrenheit. A bedroom drawer, closet, or cupboard outside the bathroom is ideal. These locations are dark, dry, and protected from extreme humidity and temperature changes.
Another critical factor in preserving your fragrances is to keep them away from light, both natural and artificial. Light can break down the scented liquid's composition and even melt plastic bottles. Therefore, it is best to store your fragrances in their original opaque containers, as exposure to air can upset the chemical balance and accelerate alcohol evaporation. Additionally, keeping the fragrances in their original boxes can drastically increase their lifespan. The boxes protect the bottles from light and other environmental factors.
The quality, scent family, and storage method of a fragrance significantly impact its longevity. Some perfumes can last upwards of ten years if stored correctly. By storing your fragrances in a cool, dry, dark place, you can extend their lifespan and enjoy your favourite scents for longer.

Frequently asked questions
Perfumes do not have a fixed expiration date. Their longevity depends on factors like quality, scent family, and storage. However, if your perfume is more than two and a half years old, you should test it for signs of expiration. Common signs include a change in scent, colour, or consistency.
Perfumes are best stored in their original containers, in a cool, dry, and dark place like a bedroom drawer or closet. Avoid exposing the perfume to air, temperature fluctuations, and direct sunlight as these factors can alter the chemical balance and cause the perfume to expire faster.
This could be due to oxidation, which occurs when the perfume is exposed to oxygen. Additionally, each time you wear a scent, you may pick up on different facets that you didn't notice before.
To enhance the scent and longevity of your perfume, apply it to moist, damp skin, or on your pulse points (wrists, inside elbows, back of knees, behind ears, neck, and chest). You can also spritz it on your clothes and hair for a full-body perfume experience. However, avoid combining conflicting scents on your body and clothes, as this can reduce the potency of your perfume and create an unpleasant final scent.
