Did you try using Curves on adjustment layer and then masking out what you don't need to be brightened up.
That is:
-roughly select areas that you want to brighten
-go to Layer>Adjustment Layers>Curves, now you automatically get mask applied which you can fine tune later
-make adjustment with Curves for desired look
It is always good to overdue the adjustment a bit and later use the Opacity slider to make it just right.
Levels should also work with that.
