What are the top, middle and bottom notes of perfume? How long does it usually take for the top, middle and bottom notes of perfume to last?

I often hear people introduce perfume as having top notes, middle notes, and base notes, which makes me feel that perfume has very rich layers and is also quite particular. So do you know what the top, middle, and base notes of a perfume mean?

Perfumes are generally divided into top notes, middle notes and base notes. The top notes are the first scent you smell when you come into contact with the perfume, the middle notes are what appear after the top notes disappear, and the base notes are the lingering fragrance of the perfume after both the top notes and the middle notes disappear, mixed with the smell of the skin again. At this time, we call it the base note of the perfume. Every perfume with the same smell will leave different base notes when sprayed on different people. When we choose perfume, we must choose perfumes with these three base notes more obvious, so that you will feel more wonderful when you taste these flavors. The middle note is generally the most important part of a perfume. It is emitted after the top notes disappear. This smell is often retained for a long time, which can last for about several hours or even longer. It is the essence of a perfume. However, compared with the middle note, the base notes of some perfumes are retained longer than the middle note. Sometimes, the scent of the perfume can still be smelled the next day, which is generally the base note of the perfume.

1. Top notes are also called top notes, which are the first smell of the perfume that reaches the tip of the nose. Generally, the top notes last for about 10 minutes. At this time, the smell of the perfume is relatively strong, but it will gradually become lighter with the exchange of air and time. It should be noted that the top notes are not the real smell of the perfume.

2. The middle note is called the main note, which is a very important part of the perfume, that is, the core of the perfume. The middle note usually lasts about 1-7 hours and can better express the inner world and charm of the user. Perfumers have also thought of many ways to make the fragrance at this stage more lasting.

3. The aftertaste is the lingering fragrance, which can last for a whole day or several days. It has a very good effect of integrating the fragrance of perfume.

Domestic flights only allow cosmetic liquids to be carried on board, and each must be less than 100ml; international and regional flights stipulate that each liquid cannot exceed 100ml, and the total volume cannot exceed 1L. Please note that the volume of the container for perfume cannot exceed 100ml. If you use a 101ml container to hold 98ml of perfume, you are not allowed to bring it on board. When carrying perfume, keep it in a separate sealed bag to facilitate inspection by the staff.
