The face and style capture files (*.facecap and *.stylecap), that can be found in your user "Documents/Adobe/Character Animator/Characterizer" folder, or by right-clicking on the square image thumbnails in Characterizer and revealing them in Explorer or Finder, are actually just zip files.
You can unzip them as a regular zip file by adding ".zip" to the end of the filename first, and see they're composed of a bunch of image files and a text file that contains the detected facial features in image coordinates. You'll notice that the face captures contain some additional image files compared to the style captures, but in general are very similar.
You should then be able to edit those images in Photoshop and then zip them back together. There are only a few things you have to be aware of to make those edited captures work.
* The content of the zip archives is in their root, not in a subfolder. This means you have to zip the files by selecting them at the same time, not by zipping a folder that contains them.
* All the images have to have the same image size.
* All images have to be stored as PNGs, except the face (not style) appearance, which is a JPG image.
* The hard segmentation image should only contain the five colors that are in it. So if you're editing it in Photoshop, it's good to use hard pencil instead of a soft brush.
