Weird Green Area on SSS Skin

I’m trying to make a skin shader for a human character, but I’m experiencing a problem with the SSS. It seems to be showing small bits of green on the model. Below is an example of what I mean. Around the eyes and around the mouth is some green light being cast, but I don’t know where it’s coming from. Sorry about the low quality of the head model. I whipped it up in a few seconds just to show my problem.

Here are my material settings (I got them from here):

What could be causing this problem?

It’s due to the algorithm that Cycles uses to calculate SSS.

You can mitigate though by mixing in multiple SSS shaders as well as a diffuse componet (optionally you might want to decrease the blue scattering distance a bit further to reduce it even more).

Mix in more SSS shaders and a diffuse? Can you show me the node setup for this?
