Anytime this question is raised it is always going to depend on the reason of the intended image.
Your shot shows more texture because it is an extreme close up and the light design. Perhaps a certain foundation would conceal some of the texture or shoot her with flat light. I am not saying showing texture of skin is bad.
She has good skin but not flawless. Your model in my opinion on this image presented will not be doing any close up beauty make up ads the way I see it presented here. There are some bumps and a dimple smoker line that some might frown on for close up work. I can see her in many other things worthy of modeling.
Fantasy, Glamour, Art, etc could have a reasonable amount of softening, if desired as long as it is done nicely and not what we see in so many cases. Nothing wrong with creating images in art form for an IMAGE Merit.
If it's designed for character or commercial/lifestyle then skin softening(blur) techniques are not what is usually desired. In other words, real life should result in real life.
Agencies have "go sees" for a reason.
So how much is too much, you ask?
Put the image itself in context. However you present it, for what it's for, will determine the best opinions towards a question like this.
