Haha
I really have seen a lot of Asian women. I think you're just being ridiculous now...
And I'm sure it's partly genetic, as even her father looks 15-20 years younger than his age.
But she also does all the things we know about: She has cut out meat, she eats lots of vegetables, protects her skin, eats light, exercises, and uses skincare products.
While diet and lifestyle (exercise, etc) certainly play some part in the preservation/deterioration of your looks as you age, the most likely (and by "most likely" I mean "almost certain") explanation for the women in the pictures is at least one cosmetic surgery procedure, along with numerous treatments (botox, juvederm, etc), plus a copious amount of makeup.
It's likely that a lot of people here underestimate the effects makeup can have on a person's appearance. It's not uncommon for skilled application of makeup to result in someone looking like a totally different person:



And these are just some examples. Asian beauty products in particular are designed to present a "juvenile" (i.e. teenaged or childlike) visage (see Korean BB cream and other Korean skincare products in general).
Research does demonstrate that Asians (and Blacks) do age more "gracefully" relative to other ethnic groups, so there is some truth to the "conventional wisdom" about it:

Skin aging is also associated with progressive atrophy of the dermis and changes in the architectural organization leading to folds and wrinkles.25 Asian and black skin has thicker and more compact dermis than white skin, with the thickness being proportional to the degree of pigmentation.26 This likely contributes to the lower incidence of facial rhytides in Asians and blacks. In addition, darker skin types are thought to have more cornified cell layers and greater lipid content compared to white stratum corneum.27,28
However, the disparity between the age and looks of these Asian women is simply too radical to be the result of pure lifestyle or other natural factors. They're either lying about their age or they're surgically/cosmetically altered. End of story.
