I got said nasty eye infection from an eye cream that was suppose to "smooth fine lines and crows feet". Well, whatever. I ended up with a pus-inflamed red eye lid that looked like I had something contagious! I stayed home for DAYS people! If I would have seen someone like me (Cyclops) walking around town... I would have gathered up my small children and ran the other way--FAST!!!
The point is, don't take chances with makeup (especially anything that goes near your eyes). When it doubt--toss it out! I've always tossed questionable left-over food and milk past the expiration date without hesitation. But, I guess sometimes a gal just has to learn things the HARD WAY! LOL!
I found this cool info-graph telling you when to toss it OUT!
WHEN IN DOUBT...TOSS IT OUT!!!
