Why does a perfume's scent change over time?
The scent of perfume changes over time after application, a natural phenomenon that can be explained by the interaction of the three layers found in every perfume bottle: Top Notes, Middle Notes, and Base Notes. Each layer has its own characteristics and evaporation rate, and the changes occur due to the different evaporation behaviors of the molecules in each layer.
The reason perfume scent changes over time is that the molecules in each note vary in size and evaporate at different rates
o Top Notes contain small and light molecules that evaporate quickly from the skin, causing their scent to fade shortly after application.
o Middle Notes feature slightly larger molecules that evaporate more slowly, allowing their scent to linger longer after the Top Notes have dissipated.
o Base Notes are composed of the heaviest and largest molecules, making them the slowest to evaporate and the longest-lasting.
In summary
Perfume scent evolves over time due to the varying evaporation rates of molecules across its three layers. As the Top Notes fade, the Middle Notes emerge, followed by the Base Notes that leave a lasting impression. This natural progression gives a perfume its depth and unique character during wear.
Understanding how each layer transforms over time can help you select a fragrance that perfectly suits your preferences and fits different times of the day!
