Undecided Question

I have a skin care problem help !?

- i have brown skin
- my face is really oily
- wash my face with aveeno bar soap like twice a day
- no i DON'T wear foundation unless im going out (like party church etc.)

when i wash my face in the morning, my forehead feels kinda sticky & i see like white stuff ( it looks like glue from a glue stick) all across my forehead & sometimes near my nose. its only there after i wash my face. btw, my forehead is the oiliest.

do you know why this happens?
should i switch my soap?
wash my face more often?
