I usually know when some of my makeup is old, like that Juicy Tube that is all nasty and separated, but I just won't throw it away. Items that are clumping are a given, but with some products I am simply clueless. When did I buy that Smashbox mascara? It doesn't seem like that long ago. Or my Betsey Johnson lipstick? Sure, it's no longer in production but it can't be that old can it?

The answer is yes, it can, and it is ,that old. It's pretty important to know that sort of thing. Bacteria and all sorts of nasty germs can fester in our old cosmetics and there is nothing glamorous about that.

Thank goodness for Timestrip. Timestrips are adhesive strips that stick onto your cosmetics and let you know when they have expired. Not a bad idea and judging by the photo they are pretty aesthetically pleasing too.

Would you use Timestrip or just take your chances on bacteria ridden beauty products?
