Lipstick will stink after being used for a long time because after each use of lipstick, lipstick will fully contact with human saliva, producing bacteria, and lipstick will produce odor.

After each use of lipstick, wipe the lipstick cream with a tissue in time, and be careful not to leave saliva or other substances.

The ingredients of lipstick are pure natural vegetable oil. If it takes a long time, the oil will change and produce an odor. The shelf life of lipstick is generally about one year. Once the lipstick is opened, try to use it within the shelf life. After the paste goes bad, it will definitely smell.

It should be noted that a lipstick can only be used by one person and cannot be shared with others.

Avoid different saliva contact lipstick, resulting in bacterial odor.
