"Cutout Opacity" changes my G8F's skintone

Hey there!
For a render I need a G8F figure where only her face, head, neck, hands, and feet are visible.
So I used cutout opacity on a G8F's torso, arms, and legs.
In a way it works, the parts that should disappear indeed disappear.
But strangely, this also changes her skin to an ugly, greenish tone.
See attachments; you can see on the face (where no cutout opacity is applied) how her skin is supposed look like. There's a clear difference to the back of her head (which is part of the torso map.) This difference was not there before I applied cutout opacity, and I changed nothing else.
What's happening here, and how can I avoid it?
Thanks!

I think that applying cutout opacity essentially disables the SSS. You could probably use geografts to hide the mesh you don't want visible, or just use the Geometry Editor to set selected polygons invisible.
