My Asian GF is 26 and works in the Chem lab at a University. It's extremely frustrating for her because students always think she is just another freshman and don't listen to her or respect her. While I on the other hand look forward to many years with my hot 18 year old looking girl

....yeah you wish, wait until she looks for another fellas when she's 30 and you starting to wrinkle

.
Actually, looks like that is not always about race.
Scientist said that it might be the skin capability to absorb vit E which make them look more young than other.
Most of Asian also live at high humidity area, which also makes the skin more humid than people in not so humid area.
I live in Asia. My wife has a grandma whose 70's, and you won't even believe that she's on that age.
If we ask her what's the secret, she answered truly doesn't know. She said that she occasionally swim at magic river which known can make people who swim there eternally young. But her sisters which always swim at the same place don't have the privilege as her.
And the look is passed to only 1 of her daughter.
I'll take a picture when I met her again (the grandma)
