Looks to me like the makeup she's wearing is too thick. I've noticed that, about some red-haired women in particular, that they often wear makeup that is so thick that at any reasonably close distance, you can clearly see that it is not skin that you're seeing on her face, but a substantial layer of makeup. It looks fine from farther back, but it looks unattractively fake, from very near. Of course, these pictures were taken from very near, perhaps the optimal distance to most enhance the unattractive fakeness of the look.
I suspect that the reason for this is that red-haired women, in particular, tend to have a lot of freckles, that they think the freckles are unattractive, and that that is how much makeup it takes to cover them. That would appear to be the case here. The makeup seems to be thinner on her forehead, and you can see a few freckles showing through; and also some freckles on her shoulder in a few of the shots.
I have a hard time imagining that the freckles could be as unattractive as the excessive makeup that it takes to cover them.
