Why do koreans have such good skin?

Koreans and Japanese traditional practices for the body (not skin)?

• I just noticed that the Asian women like Koreans and Japanese have the most ideal body. Just want to know what the average Japanese and Korean women do to have a body like that? Don't tell me it's genetics, cause I know that possibility. I'm trying to figure out something like their lifestyle. Or the traditional practices they have and are maintained till now. Any Koreans or Japanese there to share their native practices? Thanks in advance, I'm hoping for someone to understand what I meant. Thank you very much for reading!

• Answer:

  How about drinking green tea? And the food they eat. In a way, drinking green tea every day is like a diet- many people do it and it improves your body function and heart.
