I promised a few weeks ago I would do a video tutorial on a retouch example I posted a while back. This is not a quick and easy retouch process, however, some of the steps can be made into an action if you're familiar enough with Photoshop, which should help speed it up.  This is also a little different than some tutorials I've seen on retouching.  This technique keeps the skin texture intact and looks very natural, not plasticky or overdone.
