If you have a render artifact, please post your render settings.
Sometimes a slight minor change can solve the problem.

Also check that close geometry is in another SSS Group.
Teeth, inner mouth, eyes, cornea should be in another SSS group then the outer skin.
Some blue shine can come to the surface when all are in the same SSS group.

Same for close fitting clothing, that also should be in another SSS group.

There really are too many improvements in SR2 to roll back to SR1.

But if you feel you have to. . .
Post render examples and your render settings please.
