A lot of women have that facial fluff but it gets more pronounced if you don't eat enough or are not faddy diets.
As for the aging, I'm not shocked. The trouble is we're so used to seeing KW in very hightly over photoshopped images of herself in magazines, movie posters....and especially advertising. I walk past a jewellery advert she features in most days at they airbrush 15 years and about 4 stone off her. So when you see her in real life it's a bit odd.
