The boobs' stretchmarks are perfectly fine. Anyone who has lost and gained or gained and lost weight or grown in any way has stretch marks, regardless of age. I had my first stretchmarks at 12 when I grew 5 inches in one summer. Were they wrong for my age? No. They were what happened, period. Often it's also genetic, some people are more prone to them than others. So like, that's fine and good for her for not feeling like she has to blur them or whatever. There's little one can do to truly erase them beyond super expensive laser treatments that aren't always effective.
The sun damaged skin though? That is 100% preventable and as someone who gets sent loads of products for free, she surely has some good sunscreen somewhere. Plus, part of her job is to advertise creams and treatment and her poor fried skin (you can almost hear the crunch) isn't it.
And yeah, the way she behaves with posing half naked sometimes and then being all "why are you people in my business?" is so bizarre.
