Does lipstick have a shelf life

Generally speaking, when the lipstick is not opened, the shelf life is about 3 years. The shelf life of lipstick after opening is about 12-24 months.

Look at the color: the color degradation of deteriorated lipstick is obvious, and the coloring is particularly uneven, so it is not smooth to use. (KouGongYouBaoZhiJiMa)
