Food expires, and so does make-up. Even if the color is discontinued, or if you still have some left you need to throw it out. Expired foundation can cause break outs and expired mascara can cause a pink eye infection. If you can't remember when you bought it, throw it out! Most of you women will probably have an empty make-up bag after reading this, but most make-up expires after a year so you have plenty of time to save for the new year.
