What is the shelf life of lipstick?

I believe that everyone is very familiar with lipsticks. Everyone knows that lipsticks are a must-have cosmetic for girls. Some people even dream about lipsticks, so everyone will choose to collect lipsticks, but it is not recommended to buy too many lipsticks at one time, because the shelf life of lipsticks is generally about three years, and some lipsticks will have a shorter shelf life.

Lipstick is a very popular cosmetic among girls in life. Some girls often forget how long the shelf life of the lipstick is after buying it and using it for a while. So what is the general shelf life of lipstick? How long can lipstick be stored?

1. Generally about three years

The shelf life of lipstick is generally about three years. Usually when you buy lipstick, you can see the shelf life of the lipstick on the packaging, and this shelf life actually indicates how long the lipstick can be stored unopened. That is to say, if you open the lipstick, its shelf life may not be as long as three years. This is because the oil and wax contained in the lipstick are more likely to absorb impurities such as dust. Once opened, its shelf life will be more easily affected. Therefore, it is recommended that the opened lipstick can only be used for a maximum of 18 months or two years.

A must-buy cosmetic for many girls is lipstick, and there are so many colors of lipstick that many girls accidentally buy too much. If they buy too much and cannot use it all, the lipstick will expire. When faced with expired lipstick, most people would choose to throw it away, but in fact, expired lipstick can also be turned into treasure. For example, you can use expired lipstick as a crayon for painting, or you can apply a layer of lipstick on tissue paper to wipe silverware, then use a sponge dipped in detergent to wash it off to remove black stains.

Some expired lipsticks still look like they are in good condition, so some people can’t help but continue using them. However, this practice is not advisable, because some chemical ingredients are added during the production process of lipstick. After the shelf life, these chemical ingredients will deteriorate and may produce harmful substances. Continued use may cause allergies and redness, swelling and ulceration of the lips. Therefore, it is recommended that you try to avoid using expired lipstick!
