I've only tried the trial for Portraiture; it puts a grid over the image if you haven't paid for it, but you can get a hint of how well it works thru the gridwork. Here's a StockXchng image -- before and after -- this was just using it on automatic -- probably too much smoothing of skin irregularities? It does allow some control over the strength of the effect, and it offers a number of choices -- Normal, Medium or High Smoothing and Enhancement settings of Glamour (see image below next to "before/after"), Tones, High Key and Low Key.
Here's one thread at DPreview discussing the Portrait plugin, and some of the posters actually have the working software -- I haven't read it all yet, but one good retoucher on the forum agreed that it is a time saver and has a good masking function.
