Does mineral makeup foundation go out of date?

I've had this mineral makeup now since December 2008, it's now July. I was wondering if it goes out of date? I've never used a mineral foundation before. But was thinking maybe it might not be good for you after a certain amount of months? Can someone explain a bit about this please?Does mineral makeup foundation go out of date?
all make up has an expiry date on it somewhere usually there's a wee picture of a pot on the label with a number next to it and the number is the number of months you should use it for before you should stop using it!Does mineral makeup foundation go out of date?
all beauty products has an expiry date on it. It has a number on the label as a guide as to how long you have with that particular product.
dont use after expiry date over
Yeah it goes off - you shud get rid soon. 6-12 months
