Perfume expert, Serrano McLean, tells the Southern Living website that most types of perfumes have a long shelf life of up to 3 years, which begins with opening the perfume bottle, as once the perfume is sprayed, air enters the bottle, which leads to the oxidation of the perfume over time.
The shelf life varies from one perfume to another depending on the ingredients and conditions in which it is stored. According to Maclean's, perfumes that contain citrus essential oils such as lemon and grapefruit oils, or natural flowers such as bergamot or rose, expire faster than those that contain ingredients such as Musk, woody scents also have a degree of chemical stability and are more resistant to oxidation, which is why they remain usable even after 3 years.

Quoting the “InStyle” website, perfume manufacturing expert Jacques Hockler adds that a perfume bottle can last for decades if it is not opened and remains tightly closed, and this depends on the chemical composition as well as the conditions of storage and preservation in a cool, dry, dark place. He added, “I have had "The opportunity to evaluate a bottle of perfume that had not been opened since the 1980s was quite good."
Hockler pointed out that the shelf life of perfumes is now extending for longer periods than before, after many of their manufacturers have turned to using stabilizers and ultraviolet filters that make perfume molecules less sensitive to oxidation. According to Hockler, “You may have the opportunity to own a variety of perfumes at the same time.” They are used on different occasions, but you should finish the bottle of perfume before starting to use another.”
Signs of perfume expiration
The perfume expert explains that the smell and color are important to ensure the expiration date. If the smell is different from what it was when you purchased the perfume, or if it emits an unacceptable or somewhat unpleasant smell, or if it loses its luster or changes color, these are all signs that indicate the packaging is spoiled, according to Maclean’s. “Most perfumes are either colorless or light yellow, and once the perfume molecules change and lose their potency, they appear darker or take on an orange colour.”

The Makeup website lists a set of perfume expiration signs as follows:
Change in smell:
If the smell of your perfume changes to acidic or metallic, it may have expired. However, if it turns to the smell of vinegar, it should be disposed of immediately.
Crystallization:
If small crystals appear on the perfume bottle, it is time to throw it away. In general, the greater the volume of air in the perfume bottle, the lower the quality of the perfume’s scent and its stability rate due to the chemical reaction between the perfume components and oxygen. Therefore, experts do not support the idea of saving the last drops of your favorite perfume for a special occasion after a year or more.
It is no longer transparent:
If your perfume was a transparent golden color and then becomes cloudy or opaque, this is another sign that it has expired. Color change: There are some perfumes that change color when exposed to light, so the pink color turns to peach (halfway between pink and orange). This is normal, because the red dye tends to fade faster. However, if your perfume was golden in color and then changed to green, this is evidence of... It expires, especially with a change in smell.
Irritation to your skin:
If skin irritation occurs after using the perfume or any allergic reactions appear, you should look for the PAO symbol (i.e. period after opening) on the bottom of the bottle to know the estimated period of time after opening.
