Does lipstick need to be refrigerated in the refrigerator?

lipstick doesn't need to be refrigerated in the refrigerator.

Lipstick is a cosmetic, and its main raw material is wax oil. If it is in high temperature, the wax oil in lipstick will melt, so it can be stored in the refrigerator in high temperature, but it is not necessary to be stored in the refrigerator in other cases.

Lipstick can be stored for three years before opening, and the shelf life is shortened to one or two years after opening due to contact with oxygen. When the color of lipstick changes or smells bad, you should stop using it. In addition, the pigment or dye contained in lipstick determines the color tone of lipstick. Generally, it can be divided into three categories: organic colorants, mineral pigments and pearlescent pigments, among which mineral colorants are the most used colorants.
