Yes. About a year after thay are first open, they are said to expire and you should throw them away (or so the experts say. I have kept them longer than that and they seem to work fine)Are lipstick tubes suppose to be discarded after a certain length of time? If so, when?
Lipsticks usually have an expiry date on them,


if you opened a new lip balm and use it everyday


then it should be fine, and you should use it till its


all gone. But if you buy lip balm and use it once


or twice then leave it somewhere for a while its


best not to use it anymore because bacteria can


start to build up, as to lip balm you use every


day.
