maybe my foundation is not suitable for me? I think I have generally dry skin on the forehead and such but normal skin or oily skin on the cheeks. I'm using both the Clinique real makeup liquid foundation and the mousse foundation

It looks good and covered up when I've jsut put it on but give it an hour or so (even in aircon) it disappears! I don't understand.

Or perhaps my skin is bad? It looks rough these few days because of poor sleep
