So now you've got two new points in your curve.

All you need to do now is to make the line between the two steeper. Experiment with it, and see what looks good to you. 

This type of a curve is called an S Curve, for it's shape. It's the most basic of curves.

The top point in my curves here is the cheek highlight, and the lower on is the shadow of the cheek. By making the shadow a little darker (draggin it down) and the highlight a little lighter (dragging it up), I've increased the contrast in the tonal range of the man's face.
Take a look at the curves dialog here. There is a line running at 45°. This is the curve. When it's straight it's telling you that what goes in, is what comes out. The curve is not changing any values.

The most basic concept in curves is that you want the steepest part of the curve to be in the area of interest. Contrast gets our attention. But in order to steepen the curve in one section, it has to be flattened in another. So all moves in curves come at a cost. You are drawing attention to one area at the expense of another.
Now we're going to set the white point. 

Create another adjustment layer for the white point. Remember, Layer>New Adjustment Layer>Curves.

When the curves dialog opens, double-click on the white eyedropper, and set the values for white at R247G247B247.
