I'm writing a sci-fi screenplay and I wonder how a human face of an adolescent would look if it was somehow covered with a sort of flexible mask since birth? What would you discover if you removed the mask? What are the effects of constant irritation and absence of light on the skin? Would there grow hairs like after a cast? Is there a possibility that the skull or muscles are deformed by constant pressure? Would the skin start to fester? Or would it just be a pale, but fairly normal face?

Thanks in advance!
