Don't be reluctant to throw away those lipsticks that look good but have been put on for too long The shelf life of lipstick is generally about three years. Half of the lipstick is used after opening it, and it is best to use up all of it within a year. Otherwise, it is best to throw it directly into the trash can. Because the oily nature of lipstick accumulates a lot of dust and bacteria, long storage time is not only prone to deterioration, but also harmful to health when used. How to judge whether a lipstick or lipstick has deteriorated? Most lipsticks contain ingredients such as jojoba oil and grape seed oil. After these ingredients are decomposed by bacteria, they will rot and produce odors, so if they smell abnormal, throw them away.
