Do I have to throw my make up away?

My whole make up bag was in a car for 4 weeks with outside temperatures between 89F and 104F (32C - 40C). I should get it back tonight, so I haven't checked how it looks/feels/smells by now. I don't worry about the powders, but about the liquids.

Does anyone have experience with this? Do you think it will still be good?
