Have you ever checked the expiration date on your sunscreen/sun block?
I noticed it yesterday for the first time ever.
Yeah, but not the stuff I bought most recently. Which apparently wasn't all that recently. Says it expired in June 2013. That sucks, since I only bought it in 2012.
I'm betting the titanium dioxide part still works, at least. Will the rest kill me?
I've read it should be okay for ~3 years unless it smells funny or you can tell its separating/crystallizing but I'd use it with caution.
I never thought to do that, but then again, I don't use it often and it's usually borrowed.
I haven't either and apparently mine is still okay, it expired in 2006 and I'm not burning when I use it.
I wonder what expiration dates are for, then.
Expiration dates just mean the company had evidence/test results that at that age the product is still effective. Usually, companies only test as long as required instead of spending the money to test a product's actual life span.
Ah, well that makes sense. Very interesting. I wonder if there's any way to speed up the process.
No, I have never used it on my self.

Maybe, expiration dates just mean how long the company tested it and can prove it is effective. If it doesn't have a date it still should be good ~3 years but from what I read as long as it doesn't look or smell funny it may still be okay just less
effective. Use more or more often or toss it.
Sunscreen loses effectiveness after ~3 years. I just noticed mine expired in 2006.
