I doubt it. Nigella Lawson is of 100% Ashkenazi descent.
I've been following her for years on her various tv cooking shows, and I've never noticed any drastic changes. She's obviously had botox on her forehead, but so has the other woman. No woman in her fifties has no horizontal lines on her forehead. However, you can tell she hasn't had lots of facial botox, because people who do start getting "lumpy" faces. I'm sure Nigella also has had dermabrasion on her face, facials and on and on, and also she clearly wears make-up to disguise some natural signs of aging.
However, the differences are still there. Part of it is that as she's gotten older Lawson has put on weight. A little fat plumps out the face.
Sometimes you have to choose between your face and trying to still wear your wedding dress comfortably thirty five years later. She has at times put on a lot more than ten or fifteen pounds, however. She has also said she was always religious about not sun-bathing etc.
Part of it is indeed genetics. No offense intended, but I do think Southern Europeans (and Ashkenazim), on average seem to have "stronger" skin, with more collagen, and so have less wrinkling and sagging at comparable ages. I'm routinely guessed to be ten to fifteen years younger than my actual age, and my mother was the same.
The last part is indeed diet. I don't care how much vegetarians claim that their diet is the healthiest. I don't buy it. You need some nutrients that only animal proteins provide, and you need good healthy oils in your diet, preferably a lot of olive oil.
It's not as if she looks the same: that's impossible. She just looks good for her age.
Younger:
@Salento,
How little you know.
I look better than she does. Good genes and olive oil, buddy.
