Chiquita-82 7 years I'm using it until it gets dry sumnboutme 7 years I thought mascara expires in 6 months but I've had my Mac X for more than a year. I know, but I switch off between 3 other mascaras (Mac Pro Lash, Maybelline Lash Discovery, and Diorshow)...all of which is over 3 months old (except Diorshow, only about 1 month old)...is that bad? dmblauren 7 years i get rid of it when it gets clumpy & gross. i use it everday, so it doesn't last past the 4-5 month mark anyway. pattyxxcore 7 years i need to buy a new tube today so i've got some to wear to work. Ashly 7 years I NEVER check for exp. dates! I guess I should. The only time I get rid of old makeup is when it runs out. I used to keep pink eye in HS and had to get all new makeup every other month or so. That got annoying and expensive! vmruby 7 years Never....there's nasty bacteria that grows in an expired mascara that can sometimes cause really bad eye infections or blindness.That's the reason why they have expiration dates. BeckyBoopie 7 years i didnt know mascara had use-by dates! JT13 7 years I usually use all the mascara before it hits the expiration date...That's the one make up item I don't think I could ever live without! daniemre 7 years i usually forget it:S daniemre 7 years i usually forget it :S Lill-McGill 7 years I *try* and keep track of expiration dates... I generally know becuse if starts to get all flaky and crappy :) missro21 7 years Keep track!!!! I am a tomboy by heart except when I go to the an occasional "super" party or ball. So I don't wear makeup nor mascara often. Which is why I got a HUGE eye infection after using mascara that was possibly old. Nasty! I'm PR and a big eye is not cute when you are in the public. No eye damage, but it took two weeks to heal! The best way is to literally clean your brush off everytime with a cleaner per each use (This is how makeup artist keep their products clean.) Sounds like a lot of trouble but well worth it!!! warau 7 years I finally gave in and bought a new mascara after using the same old one for two semesters. haha It was about time! ShimmerBronze 7 years yes more so every 4-5 months simply because i use it for brow gel instead and rarely for my lashes. shini 7 years I totally forget that cosmetics like mascara have deadlines :P hhaha I think I gotta check how old mine is... iheartstarbucks 7 years I never really think about it. I usually use the tube up in 3 months;) gruaig_rua 7 years 3 months!!!:JAWDROP: I never knew this! I would never have a whole tube of mascara used in this length of time. gruaig_rua 7 years 3 months!!!:JAWDROP: I never knew this! I would never have a whole tube of mascara used in this length of time. ktjones 7 years Once in awhile...but it is usually all gone within 3 months so I do not really keep track!
