Sandra Oh hopes her natural features may have a positive impact on Korean viewers of her hit TV show Grey's Anatomy.
Oh, the Canadian-born actress of Korean descent who has played Dr Cristina Yang since the drama began in 2005, said one of the greatest accomplishments of the series was how the cast's ethnic diversity translated beyond North America.
"How other countries see faces and how that in a very, very, deep, deep subtle way opens up acceptance, opens up equality, opens up many positive things that I would like to be a part of," she told international journalists at the Grey's Anatomy panel at the Television Critics Association's winter press tour.
Oh said she had never done anything to her face, as noted by a 70-year-old friend of her mother's visiting from Seoul. "She said 'You haven't done anything to your face, have you' and I'm like 'No I haven't' and then she said 'We can tell; don't change it'," Oh said.
"I read this article recently on how K-pop has really influenced so much teen plastic surgery.
"In Korea, a lot of the images of women are images of women who have altered their face; just watch Korean dramas.
"I felt, here I am in America but this show is being broadcast in Korea and how just that can affect a population."
The prevalence of plastic surgery in Korea was recently explored on WA-made SBS documentary Change My Race.
Oh is leaving Grey's at the end of this season of the hospital drama that airs in Australia on Seven/GWN7.
