you may not want to use SSS on the EYE socket. I mean, it's hidden and you don't see it so why bother with SSS on it. That is one issue with the dark circles and sometimes the glowy rings around the eyes.

@ChromeStar I'm using the same shader on the gums, tongue, and inner mouth as I am for the skin. Just got to "bump" up the bump and gloss for those parts. It will be different for each texture/bump map you use.
