Try increasing your Shadow Min Bias to 0.5 if that is indeed mesh.  It almost looks like SSS artifact under the eyes.  Do you have SR2 installed?  What is your SSS scaling value?  A value of 1.5 or greater, not a problem; lesser than 1 you might get artifacts.  Though the image I posted has a value of 1 for SSS scaling, but I do have SR2 installed.

With render gamma correction, your light intensity shouldn't be 127%.  Way too much lighting.
