Expiration Dates?

I have a few lip products and I was wondering how quickly I would need to use them up before they go bad. I know tube lipsticks last about 1 year, but how quickly do doefoot applicator lip products go off? I have a couple liquid lipsticks and lip glosses and I have been focusing on them trying to use them up this year but I kinda want to use my other lipsticks too. I'm starting to think that instead of finishing 6 of my lip products in the year as I originally planned, I might try to finish 50% of each of my lipsticks throughout the year. I'm just wondering if by the time I reach the end of the year, my liquids and glosses would be bad.
