Photoshop Fix features

Apparently Photoshop Express incorporated all the great features of Photoshop Fix before making Fix obslete sadly.  Though this does seem the case and Express is barely patch on Fix, there has to be a face (that it can recognise) to use many features, how does one use smooth for skin or other areas of the photo without a face for example? 

Another classic case of developer @Adobe f**king with the recipe for no apparent reason. 

Thanks in advance!
