Long, luscious lashes are super sexy and can make your eyes stand out for miles. And now that you've probably found your favorite mascara you need to make sure you use it... or you'll lose it. What do I mean? If you don't use your product it will eventually go bad just like anything you'd leave out on the counter too long. So how do you know if your favorite lash enhancer is bad? The first sign is the smell. If your once pleasantly fragrant mascara is now odorific it's time to trash it. The smell could mean bacteria is present in the tube and that should go no where near your eyes. Second, if you've shared your wand... pass it on. Sharing mascara is a big no no and should be trashed (even if your pal in gym class borrowed for like, a minute, because she forgot hers). Finally, if you notice changed in consistency... dump it. Your wand should glide in and out of the bottle and there should be no cakey flakes in sight! Now that you've ingested all this info go check your mascara. If you notice any changes in smell or consistency throw out your bottle and get a new mascara today!
