That's just a common problem with ALL the official "Pro Bundle" characters from the DAZ store.
Most of them look saturated like oranges, perhaps looking like people in the old days of TV with the color cranked up to max. Not like real people.
Now if the base diffuse maps are solid orange, or even pink, you can only try to reduce the red- and other channels in the base color of the maps in the shader settings. But for everything else, there are shader settings too.
Example here, this is my "F95 slut" used for some images posted here.
IIRC she uses the materials from Godin's character "GDN Meg". They render a bit dark for my references, but this is otherwise a very realistic product out of the box. You can check this in fullscreen size, there are plenty of fine details like skin pores, it generally looks like a human being. So we're not gonna fiddle with that.

So... this is what the GDN-Meg textures look like in the viewport, and how they look in the IRAY preview.

Now i'm using different textures. These are actually from 3DU Emma which are child textures, but they show the problem real nicely (and how to fix it)

Alright so these look simply weird. MAYBE if she spent a few weeks tanning and then the tan began to wear off, but this doesn't look anything like a picture book "white redhead with pale skin".
So now i'm pulling out my magic wand, and fiddle around with the shader settings until i get this:

Day and night difference, right?
Can even go for more white and pink, like this:

Maybe a bit too stylized in the final result, but you get the idea.
Any questions, just ask. This post was mainly for demonstration.
