Can lipstick be kept in the refrigerator? Can lipstick be kept in the refrigerator in summer?

1. In summer, lipstick can be kept in the refrigerator. If the lipstick is not used for a long time, it can be kept in the refrigerator for a long time. However, it should be noted that the lipstick should not be taken out from the refrigerator for use from time to time. This will cause the moisture in the lipstick to be lost. Therefore, the lipstick should not be taken out of the refrigerator for use too frequently.

2. The main ingredient in lipstick is wax. Wax has a relatively long shelf life, but most lipsticks will cause mold to grow due to long-term absorption of moisture in the air. Under normal circumstances, lipstick has a service life of three years and a shelf life of one year. If it has been opened, it is better to use it within three months. Lipstick should be stored in a cool place. In summer, the temperature is high and the humidity in the air is relatively high. Lipstick is prone to moisture problems or deterioration problems due to excessive temperature, so lipstick is generally stored in a cool place. It can be placed in the refrigerated layer of the refrigerator, tightly closed, packed in a disposable fresh-keeping bag, and placed in a small box, so that it can be effectively isolated from other food in the refrigerator.
