Why do foreign women have such good skin?

Judging from the Korean sister paper that I came into contact with since childhood, I want to say that this is the * * * interaction between congenital factors and acquired maintenance. My first contact with Korean sister paper was in junior high school more than ten years ago. The parents of Korean sister paper in my class work in China. She met almost every day from elementary school to middle school, which basically confirmed that she had never moved her face. The appearance and skin of Korean sister paper are really average, but in terms of obvious characteristics, it is no different from our Chinese sister (not demeaning). The skin has the common problems of adolescent girls, a little acne and acne. Her background is really white, and the group of Korean sister papers with her is even more general, and some of them have dark and rough skin. In fact, our Chinese sisters are also like this. Some are born with good skin, while others are generally similar. Excluding congenital factors is acquired. At this point, I have to say that Korean sister paper really started with dolls for the cultivation of makeup and the like. More than a decade ago, when junior high school students basically didn't know how to make up or dye their hair, Korean sister paper in the class began to apply BB cream every day, modified their eyebrows and dyed their hair. Later, I went to college, including reading a lot of Korean sister papers during the American imperialists. Basically, the level is uneven, so there are individual differences. However, they attach great importance to makeup and grooming. When they were in the American imperialists, they knew a Korean MM who was studying medical school. Her schoolwork is so heavy that she can't sleep every day, but she insists that no matter how early she goes to work every day, she must get up more than an hour in advance to make up and never go out without makeup. Besides, I feel that Korean girls do have that gene. When I was an undergraduate, some of my classmates were Koreans. This MM looks quite Korean, with a cake face and small eyes, and her skin is round and smooth, white and tender. So you see, either you have an innate advantage or you try your best to manage your own image. Of course, the overall feeling is good.
