I noticed that too. There could be many factors like staying up late, drinking too much alcohol, not taking care of skin etc.

But here is something a FL in Beijing told me a few years ago. She was a very sweet, mid 20s, could talk in English. I fucked her a few times in hotel. She told that she used to take only 2 or 3 customers per day (also a part time travel guide) because she wanted to take care of her figure and serving too many guys has adverse effect on attractiveness of figure as she has seen among her friends. So this could be a reason too.

(BTW, She also told that she liked white guys and was looking for a husband. She eventually did get married to someone in Texas and living happily, enjoying holidays all over the world, musical concerts etc. Unfortunately she unfriended me on her personal Wechat account last year.)
