How is that lit?  I can tell there is at least one light that is set to have no shadows (specular coming from the inside of the mouth) - this is bad, and can provoke some really bad artifacts.  E.g. light from behind the character's head hits the back side of the eyelash polys and bounces around in an impossible way.

Do you have AO on for any lights?  If so, turn it off.  Do you have AO on for any materials?  Turn it off.

P8 still has a problem with blotch artifacts, which can appear in places where you have geometry close to other geometry (like your eyelash problem).  These are hard to predict and sometimes hard to correct, usually I have to just move lights around more or less at random.  The IDL solution itself is somewhat random too, and blotch artifacts can appear in different locations (or if you're lucky, not at all) even if other conditions are not changed.
