Something worth checking out. http://www.portraitprofessional.com
I just picked up this program for 50 Euro and wow... !!!! I have to say it's extremely powerful.
Here's a very casual shot I took with my wife's camera.

Notice that not only is the skin airbrushed, the actual shape of all the features are changed and their reflection has changed. The mouth and eyes are the most noticeable.
