Typically, the shelf life of cosmetics is 2 to 3 years, and the usage period after opening is about 6 months to 1 year.
Lipstick, in particular, has a shorter shelf life than other products, around 6 months.
This is because there is a risk of bacterial contamination due to exposure to air, and since it comes into direct contact with the lips, it is easily contaminated by saliva, etc.
When using several different colored lipsticks together, you often end up exceeding their expiration dates, so I think you need to be careful.
