How high can make-up be heated before it spoils?

I left my make-up bag on the radiator for a bit and I was wondering if the make-up would still be OK to use. In the bag were eyeliner, eye shadow, mascara, foundation, concealer, lipstick. Thanks a lotHow high can make-up be heated before it spoils?
I don't think there's a specific temperature that will spoil makeup, really, it might just melt it an alter the consistency...I'd check anything that was in 'stick' form...if it was left there long enough, it'll be a melted mess.





The shadow, as long as it was powder, should be okay, the mascara should be alright too (after an hour or so), the foundation should be okay if it was powder, (hopefully it wasn't a stick), and the so long as the concealer wasn't a stick, either, it should be alright.





The liner and lipstick are probably the only things really affected. You can totally melt down the lipstick into another lipgloss-jar or something like that and use it from there...not sure how you should go about re-using the liner.





Anywho, best of luck.
