How long can a lipstick last?

A lipstick can be used for one or two years, and the lipstick used at the same time is related to the frequency of using lipstick, so it varies from person to person.

You may run out of lipstick every day for half a year. The shelf life of lipstick is about 3 years, but for the sake of safety, the shelf life after opening can be greatly shortened, and it can be used for up to one year.

The main components of lipstick are wax and oil as well as antioxidants and emollients. The high melting point of solid lipstick is the key component of lipstick reinforcement, which provides a support structure for solid lipstick.

Lipstick uses a variety of oily substances, such as olive oil and some wool paper, and even other trace metals are also present in lipstick, so the use time is generally about three years, but this is also suitable for better quality lipsticks.

Extended data:

The main components of lipstick are wax, fuel, lanolin and so on. These substances provide good adsorption for lipstick, so that lipstick will not easily fall off and disappear when applied to lips, and at the same time increase the possibility of adsorbing various bacteria. These poisonous bacteria can enter the human body through the human mouth, causing various diseases.

Beautiful lips can attract people's attention, but at the expense of lip health. Lipstick is a modern chemical product, and a lot of chemical pigments will inevitably be added in the production process. Although the country has issued many relevant policies, which stipulate the safe content of various harmful substances, it is still impossible to avoid the possible harm of lipstick to the human body.
