What should I do if the newly bought lipstick arrives by express delivery and is put in the refrigerator?

It can be stored in the refrigerator as an emergency method, but it is not recommended to store it in the refrigerator for a long time.

When the temperature is high, the grease component of lipstick will boil out from the surface of the paste; When the temperature is low, the grease will return to the paste, leaving traces on the surface of the paste, commonly known as "sweating" or "hanging beads". This situation will not cause lipstick deterioration, nor will it affect the use.

Solution to sweating problem: put lipstick or lipstick in the refrigerator, and it can be restored after the temperature is lowered, and it can be used normally.

Precautions for using lipstick:

Lipstick shell is most susceptible to dust and bacteria. You can try to disinfect the lipstick shell with an alcohol bath. 70% alcohol is enough to kill bacteria, and the higher the concentration, the less volatile it is. Hold the lipstick by hand and immerse it in 70% alcohol solution for a few seconds to remove the bacteria on the surface of the lipstick shell. Let the lipstick air-dry naturally to prolong the contact time of the remaining alcohol, so as to achieve the effect of disinfection while drying.

If you want to lend lipstick to your girlfriends or friends, you can try scraping a small part of lipstick on the back of your hand (near the tiger's mouth) with a cotton swab or a small scraper, and then apply it to your lips after mixing. This not only ensures the cleanliness of lipstick, but also prevents bacteria from staying in the paste.
