Step 1: 

Duplicate a layer from the photo for retouching purpose

Step 2: 

Select the area of face, you may use Lasso Tool, Quick Selection Tool or Pen Tool, whatever you like. Except the eyes and mouth.

Step 3:

Apply the Surface Blur filter to the face layer.

For the Radius, and threshold value, it depends on how much surface blur do you want. Actually you can check the "Preview", then you will see the result instantly.

Step 4:

Apply the Curve layer to the "skin" layer. Then tune up the mid tune in the curve.
