The subject of this thread and my previous comments were about face reshaping, not skin smoothing.
But since you didn't address my questions, and since you brought up skin smoothing instead, you should know that just like with their face reshaping, it has large number of separate adjustments for skin smoothing, ALL of which can be set to zero, if desired. So, if you ever see a Portrait Pro edit in which the skin of the subject looks too "doll like", you are looking at a user who doesn't know what they are doing.
If you are making this assertion about "doll like skin" because you have read it on the net, but have no personal experience with the program, then you should download a free trial and see for yourself. Of course, like any complicated program, it can easily take several dozen practice runs before you get good at using it properly.
