Welcome to the forum.
One possible treatment, within PrPro would be to do a Track Matte Key, where a little bit of Blur is added. Once, there was a great tutorial on softening blemishes in skin tone, but it is no longer.
This article covers some of the high-points of the process. The success, and handwork, will depend on how much the host moves about: http://forums.adobe.com/message/4575874#4575874
Because so much can be Keyframed, and limited via Track Matte Keying, one is limited only by their imagination. I would first Duplicate the Clip, add a bit of Blur to that Duplicate, then limit that Blur to just the facial areas with a Track Matte.
PS - Beyond that, there are some neat tools in After Effects, that go beyond.
