who has no plastic surgery in snsd

yoona has no plastic surgery

I think
Seohyun haven’t done any surgery yet.

All them have plastic surgery but yoona, seohyun, sooyoung and yuri not too much

All of them got at least 1 or 2 procedures done, I think the one with less plastic surgery is Seohyun.

there is a website called kpop plastic surgery that talks about that stuff.

All SNSD had plastic surgery but enormously

Seohyun from what I've seen from her pre debut photos
