Many people are of the opinion that if the fragrance does not last long, then it is cheap or fake. It's actually not that simple.
The modern pace of life is much faster than in the 19th century and even in the 20th century, and this acceleration is reflected everywhere, including in perfumery. Fragrances change over time and gradually become less persistent, so that you can change a couple of fragrances in a day and they have time to disappear.
In addition to the trends of our time, the same scent can behave differently depending on the climatic zone. I was able to experience it myself when I took a bottle of my favorite scent on a trip. In another climatic zone, perfume behaved completely differently, and this is not in Africa, but everything within our homeland.
Therefore, do not rush to accuse stores of selling fakes, but try to figure it out with the help of publications, reviews from the Internet and personal experiments.
