I think she's taken a suggestion or two from here to heart and gone lighter with her eyeliner, or maybe I'm projecting and it's a coincidence.
But she has a much lighter, softer line on the upper eye lid, than her usual harsh and thick liquid line, for the past few days (I've watched her stories).
That's a massive change and makes her look much fresher.
The other thing is the hair cut and colour, which also makes her look much better and fresher.
If she's fiddled with her nose it was only minor surgery or filler/botox, as suggested before.
But her looking better and different has a lot to do with her hair and makeup.
She should ditch the current highlights as well, but it already is a massive improvement.
