Longevity of a perfume
Normally, opened perfumes last around 24 to 48 months without any loss in durability or intensity if they are stored correctly! As a rule, scents do not expire like milk, for example: they change the scent, the color, the consistency and the durability. It doesn't sound too dramatic at first. But after this “tilting” of the perfume, the perfume can no longer be used for its actual purpose.
Better a spray bottle than a shake bottle
In order to achieve optimal longevity of the perfume, you should always choose a perfume with a spray bottle instead of a shaker bottle. Due to constant contact with the skin, the durability can decrease significantly. You should also pay attention to the alcohol content of your perfume; the higher it is, the longer your scent will last on your skin.
This is the best way to store your perfume
Proper storage is the be-all and end-all for optimal shelf life. It's best to keep your scents in the bedroom. The temperatures there are usually constant and it is not too bright. If you want to be on the safe side, you can also store your fragrances in a dark drawer, a box or in the outer packaging of the perfume. You should also always make sure that the perfume is tightly closed with the lid. This could cause too much air to enter the bottle and the scent would gradually evaporate.
