Yea...you are a noob :tongue1:  (just kidding)

I would reload, and start again, if yo got white, cause you probably used "replace" instead of ignore

You don't really need it.  The bump is still way too high in any case.  It's on the surfaces tab of the head/face.  Dial it back.

If you do use HSSS When you apply that though, hold ctrl, when double clicking it, and choose ignore...then you got to drop the specular strength way down to 25%, turn on velvet to 10% and SSS to 25%

I would just leave any displacement off...for skin to start.
