All cosmetics have a lifespan, and most lipsticks have a lifespan of three years. But if the lipstick is opened and used, it will not be as many as three years. Used lipstick, because lipstick is very easy to breed dirt, so the general life span is only one year.
It is better not to continue using lipsticks that have expired. Why is it better not to continue using lipsticks that have expired? Although they are expensive lipsticks, they are cheap lipsticks, and they are all added during production.
Deteriorated lipstick will not only cause damage to the mouth, but may also cause damage to the body. So I suggest you try not to use lipsticks that have expired. And, the opened lipstick needs to be used up as soon as possible within 18 months to two years.
