Here is a suggestion.
Why not allow PPro to import skin selection created in Photoshop or elsewhere. Photoshops Quick Select does a great job of selecting things which other programs do not do nearly as well.
Specifically, have a skin selection import feature in PPro. That way if the user has selected skin area (w Photoshop or some other program and saved that file (in png file format for example, because png allows for transparency) PPro could import it to use to define the skin area. This would be an optional alternative to having to brush it in.
