Many factors influence how a perfume smells, including temperature, humidity, and exposure to oxygen. Some fragrances are designed to smell better after being exposed to more air, and some people believe that perfumes need to rest for a few days or weeks after opening to smell their best. Additionally, perfumes with high concentrations of alcohol and synthetic components may darken or discolor over time due to oxidation, but this does not necessarily indicate that they have gone bad. Natural oils in the perfume, as well as the presence of vanilla, can contribute to discoloration. Ultimately, individual preferences and olfactory senses play a significant role in perceiving the quality and appeal of a fragrance.

What You'll Learn
The effect of air on perfumes is not extreme
Some fragrances are designed to be at their best when exposed to more air. This is why a small spray of perfume on the skin can change over time, revealing top notes, middle notes, and base notes as the liquid oxidizes. However, the impact of air exposure on perfumes is not drastic. Some perfumes may change slightly after being opened and exposed to air, but this is not always the case, and it is not extreme.
It is common for scents to change colour over time due to the oxidation reaction, but this does not necessarily indicate damage to the perfume. Vanilla, for example, tends to stain and brown when exposed to air, but it is still safe to use. Similarly, some perfumes may change in scent after being exposed to air, but this is usually a gradual process and may not be noticeable.
Additionally, perfumes with a higher concentration of alcohol (60% or more) and synthetic components may discolour or darken over time. While these perfumes should not be applied directly to the skin to avoid potential skin irritation or allergies, they can still be used as air fresheners. Overall, while air exposure may have some effect on perfumes, it is not extreme, and other factors, such as temperature and shipping conditions, may also influence the fragrance.

Perfumes are designed to be at their best when exposed to air
Many people suspect that perfumes smell better after being exposed to air. Some people have noticed that perfumes smell stronger after a few weeks, while others have noticed that perfumes with higher concentrations of alcohol and synthetic components can cause skin irritation if they have been exposed to air and discoloured.
It is a well-known industry secret that all perfume formulations are made with a three-week incubation period. Perfumes need to "rest" rather than "breathe", and this is why unprimed bottles are not affected by exposure to air. Perfumes are also affected by changes in temperature and humidity.
Some people have also noticed that perfumes smell different when they first buy them, and that the fragrance comes through after a few sprays. This could be because perfumes are designed to be at their best when exposed to more air. As you use more of the perfume, it will be exposed to more oxygen, which will change the scent over time. This is why a single spray will smell different from a room filled with the same perfume.
Additionally, perfumes may smell differently on your skin due to high temperatures, humidity, and other factors such as mood, season, temperature, diet, and health.

Some perfumes need to 'rest' after being opened
Many people suspect that perfumes get better after being exposed to air. Some fragrances smell different from what is expected upon the first spray and/or application, but after a couple of sprays from the bottle, the fragrance soon comes through. This is also why a small spray on your skin changes over time and you get top notes, middle notes, and base notes—it is the liquid oxidizing off of you.
It is a well-known industry secret that all formulations are made with a three-week incubation period. Perfumes need to 'air' on the skin, not in the bottle. Fragrances may smell differently on your skin for many reasons, such as high temperatures, humidity, etc. Some fragrances smell best in cool temperatures, while others bloom in hot temperatures.
Some perfumes need to rest after being opened. It is very likely that all fragrances get better with some resting time as changes in temperature and other things during shipping affect perfumes. However, if your perfume contains a higher concentration of alcohol (60 percent or more) and synthetic components, a darker or discolored perfume should not be applied directly to the skin as it may cause skin irritations or allergies.
Some people have also experienced the opposite effect, where a fragrance that initially smelled good eventually starts to smell bad. This could be due to mail shock, which is more prevalent in extreme climates.

Perfumes with high alcohol content may cause skin irritation if discoloured
While perfumes are intended to be left on the skin, they can contain low-molecular-weight chemicals that may induce skin sensitization and cause allergic contact dermatitis. The presence of sensitive skin has been associated with exposure to perfumes, and some people with sensitive skin may be unable to spray perfume on their skin without developing a rash.
Perfumes with a high alcohol content, of 60% or more, may cause skin irritation if discoloured. Discolouration can be caused by oxidation reactions, which are sped up by factors such as light, heat, water, and exposure to air. Vanilla perfumes, for example, may become brown when exposed to air for extended periods. However, discolouration does not necessarily indicate that a perfume is damaged or useless, especially if it is predominantly composed of natural oils.
If you have sensitive skin, it is recommended to be cautious with exposure to scented products. To determine specific allergic triggers, you can undergo patch tests that expose you to small amounts of different allergens. Once you know what you are allergic to, you can avoid any perfumes that contain those ingredients.
Some people have reported that their perfumes smell better and last longer after having them for a while, suspecting that this is due to air getting into the bottle. Unprimed bottles, which have not been sprayed before, do not seem to exhibit this effect.

Vanilla perfumes may change colour due to oxidation
While perfumes may get better with age, it is important to note that vanilla perfumes are particularly susceptible to discolouration due to oxidation. The primary compound in vanilla, vanillin, naturally oxidises and darkens over time. This process is accelerated by exposure to air, light, heat, water, and alkaline pH levels. As a result, vanilla perfumes can develop amber or brown tones, with some even turning a dark brown colour. This discolouration is not an indication that the perfume is damaged or useless, but it is something to be mindful of, especially if the perfume has a high concentration of alcohol or synthetic components, as it may cause skin irritation or allergies.
Vanilla is a popular ingredient in perfumes due to its sweet, warm, and milky scent. However, its primary compound, vanillin, is prone to oxidation, which can alter the appearance of the perfume over time. This natural process occurs as the vanilla interacts with oxygen, causing a chemical change that leads to discolouration. The rate of oxidation is influenced by various factors, including exposure to air. When vanilla perfumes are exposed to air, the oxidation process is accelerated, resulting in a faster colour change.
In addition to air exposure, light and heat play a significant role in the oxidation of vanilla perfumes. Light, especially UV rays, can trigger photodegradation, which is the breakdown of fragrance molecules. Heat, on the other hand, speeds up the chemical reactions within the perfume, making it more prone to oxidation and ingredient breakdown. This combination of light and heat exposure can accelerate the discolouration process, causing the vanilla perfume to darken more quickly.
To minimise discolouration, it is recommended to reduce the exposure of vanilla perfumes to air, light, and heat. Choosing perfumes packaged in dark or opaque bottles can provide extra protection against UV light, slowing down the oxidation process. Additionally, storing perfumes in cool, dark conditions and maintaining a stable temperature can help prevent premature oxidation and the development of a very different scent. While discolouration may occur, it does not necessarily indicate that the perfume is no longer usable. However, if the perfume has a high concentration of alcohol or synthetic components, it is advised not to apply it directly to the skin to avoid potential skin irritation or allergies.
While vanilla perfumes may change colour due to oxidation, this does not diminish their allure. The unique scent of vanilla, with its sweet and warm notes, continues to captivate perfumers and wearers alike. The colour change is a testament to the complexity and artistry of perfumery, and the evolution of the fragrance over time can be enjoyed and appreciated by many.

Frequently asked questions
Yes, perfumes can get better after getting some air. This is because perfumes are often designed to be at their best once exposed to more air, and this is also why you get top notes, middle notes, and base notes. However, perfumes with a high concentration of alcohol (60% or more) and synthetic components should not be used if they have been exposed to air and become darker in colour, as they may cause skin irritation.
Air can impact perfumes by causing an oxidation reaction, which can change the fragrance. This is a well-known industry secret, and many perfumes are designed with a three-week incubation period to account for this.
It is recommended to let your perfume rest for a few days to a few weeks after opening it for the first time. Some people recommend spraying a few sprays onto a cotton pad first, while others suggest that perfumes need to "'air'" on the skin rather than in the bottle.
