Here's my guess.
You have a light directly behind her head and shadows are not enabled for this light. Light is leaking through and illuminating her face.
The reason is that RSS (and any proper skin shader) implements Fresnel specular reflection. This means that you get strong specular effects when the light hits the skin at a very shallow angle of incidence. When you set up a light like this it's called a rim light, because it highlights the rim of curved surfaces.
This is usually desirable as it is realistic, but not without shadows enabled.
So enable shadows on the rim light.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
