Does lipstick have a shelf life?

In daily life, many women wear makeup every day. Among many cosmetics, lipstick is a kind of makeup that is particularly popular among women. Lipstick comes in many colors and you can choose the appropriate color according to different occasions. This will make the makeup more charming. Because many women have more than one lipstick, you should also pay attention when choosing a lipstick, because lipstick also has a shelf life.

How long is the shelf life of lipstick?

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.

2. Expiration processing method

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.

3. It is best not to use expired

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 may deteriorate and 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!

Precautions

The shelf life of cosmetics such as lipstick is generally about three years, so some girls think that a lipstick can be used for three years. But in fact, the shelf life on the packaging of lipstick and other cosmetics often refers to how long the lipstick can be stored in an unopened state. Generally speaking, opened lipsticks will have a shelf life of less than three years due to the absorption of bacteria, dust and other factors. Therefore, the opened lipstick should be used up within one to two years.
