Need help with realistic skin or close to it.

Hello, hope you all doing good. 

I have been working on daz for few months now. But there is a problem I am facing is the genesis figures I have bought over the time all faces looks plain and even I zoom into them I see some spots on the face which adds to realism but I dont see any skin texture as i use to see in CC4. Actually I want my character to look as real as CC4 character or less. I had searched a lot on the internet but didnot find any result on this topic. I also seardhed the shop for a texture normal map to put on but I am not sure, Maybe if you guys uses some so please let me know so I can try it or os their any other way in surfaces to edit the texture or something.
