Here is a old tutorial I am going to move over to my Jerrycentral
Make a copy of your photo.
Use the healing brush with a small brush and work on the blemishes.
Now make a new blank layer that we will work on with this technique.
Now select the airbrush tool and grab a large soft edge brush. Set the pressure quite low, you will want to experiment with this as you work on your image. Sample the skin color in the area you are about to work and begin to cover the skin that needs retouching. On the PC machines sampling is done with an Alt click.
Paint freely with the large brush as we will be able to fix any over spray later with a Layer mask. Shan says the most important thing is to not use too small of a brush.
Now the image has a fairly smooth look to it and needs some noise added to match the grain or noise of the image. Again experiment with the settings to see what works. The 6.37 turned out to be too high for my example.
