In need of help regarding textures

[pannicc]

So a long while ago I downloaded a texture replacer for UNP skinny body that was a pale skin with pink nipples. The problem is not that skin, the problem is the face. The texture for the body and the face do not match because the face is darker. The replacer I DLed did not bring face textures, it was only for the body so I had to use other ones like right now I am using one called better faces by bella or something like that. (if exact name is needed let me know and Ill go searching for it)

 

So my question is this how can I make the face textures match the body ones? I have tried doing it myself but I just cant get it to work not even come anywhere near.
