Metahuman face redness

Hi, I’m making a couple of characters in the UE 5.8.1 Metahuman editor and I have an issue with one of them.

There’s this effect of I guess blushing, when squished skin gets more red. On my other female character this is very subtle and creates a nice delicate pink/red highlight, but on this male character it’s very exaggerated to the point of completely changing his skin color. It’s very jarring to see, especially in motion when whole portions of his face suddenly become almost yellow/red.

Are there any knobs in the Metahuman editor to control the intensity of this effect? I can’t seem to locate it. If not does anybody know how to hack it out?
