Will perfume cause allergies? Does perfume need to be shaken before spraying?

Perfume will not cause infertility, but pregnant women are advised not to use perfume because some chemicals in perfume are not good for the fetus. So will perfume cause allergies? Do you need to shake perfume before spraying it?

Under normal circumstances, the use of perfume will not cause allergies. People with sensitive skin may experience skin allergy symptoms after using it. There are three possibilities for perfume allergies. The first is the quality of the perfume. Avoid buying cheap and low-quality perfumes. The second is sensitive skin. When using perfume on this skin, do not apply the perfume directly to the skin. You can spray it on the coat. The third is that the skin with perfume is exposed to the sun, causing a chemical reaction. People who are allergic to perfume should try to avoid contact with perfume. They should also exercise more to strengthen their physical fitness and improve their body's resistance. If an allergic reaction has occurred, some anti-allergic drugs should be taken for treatment. In addition, during the allergic reaction, try to avoid eating spicy, irritating, photosensitive, and indigestible foods to avoid worsening the condition.

You must not shake the perfume before using it, which is a taboo when spraying perfume. Shaking the perfume will speed up the evaporation of the liquid, and it is also easy to speed up the oxidation of the perfume, which is easy to change its taste and lose its original fragrance. The perfume must be absolutely still. Shaking is a habitual action for the public when using liquid products. It feels that shaking will not cause the ingredients to precipitate, and it can allow the ingredients to be completely blended together. This idea is correct, but it depends on the product. Perfume must not be shaken roughly, and it is best not to shake it lightly, because shaking it is equivalent to killing the perfume. Letting it stand is the correct way to treat perfume.

It is not recommended to put perfume in a humidifier. Firstly, perfume will emulsify when it comes into contact with water, and the smell will change, so it may not be fragrant when sprayed. Also, many perfumes contain preservatives, fragrances and other chemical substances. These substances are more easily absorbed by the human body after being atomized by the humidifier, causing discomfort to the body and being harmful to the respiratory tract.

Perfumes don't go bad simply because of time. They usually go bad because of sunlight and high heat. If your perfume is stored in the right way and out of direct sunlight, it will become more mellow and better like wine. Whether perfume goes bad has nothing to do with the length of time. Whether it will go bad depends on the environment in which it is stored.
