Whatever you are doing it looks really overdone. The skin looks like textured plastic. Almost like a black and white plastic orange peel.
There's a couple things going on that really stand out. Keep in mind I'm nowhere near a pro at this, but this is what I have learned. First, your model doesn't have the smoothest skin to begin with, and she is not wearing much if any makeup. Second, the lighting isn't the most flattering for the beauty type look you're trying to go for.
You would need to be very skilled/experienced to pull off something realistic with the image you have. I would have her put on some foundation or smoothing makeup and reshoot with a different light setup. More lights, more diffused, reflector under her, etc... All these things serve to soften the lighting and fill the shadows in the texture of her skin. Tons of tutorials on youtube about this. Search for Joel Grimes. That will give you a better image to work with that will be a lot easier to retouch without looking fake.
