Do Thai ladies get their bodies done professionally?

I work as a secretary at a modeling agency and we’ve been getting a lot of auditions from Thai ladies lately. I noticed that these women are really stunning; they’ve got the perfect body and a pretty face to match. Sometimes, it makes me think that some of these Thai models had their bodies or faces done. I mean there’s no way ALL of their features are natural, it just seems impossible in my opinion. Is it common for these women to get their bodies or faces done professionally? Is it an acceptable practice in Thailand? Just curious.
