I'm sure a lot of people do wonder... When do I need to toss out my makeup? Sometimes it seem like I have some stuff that's been here forever. OK, maybe not forever, but a long time. I sometimes just don't go through them or just don't want to toss them. It's not like they look old or that they smell..right? Well, I guess that can be true, but you don't want to risk bacteria..the really really micro type that you don't see being there and then applying it to your face, eyes or lips.
