PS is so common in kpop its like people wearing shoes. Which plastic surgeries in your opinion achieved the best results when it comes to aesthetics and how much it led to the idol generating profits from it? For example, IOI Chaeyeon is said to hit the jackpot thanks to her PS.
1st generation - ps wasnt as common or least not that noticeable but I give it to SES Eugene because she refined her nose slightly to enhance her visual, I think she wins for both categories
2nd gen - aesthetics: OC Nana, she gets praised a lot, but in later years the ps may have produced some adverse effects unless properly maintained
profit: Yoona - she also did some basic tweaking like Eugene and it enhanced her visual and made her popular for many years
3rd gen - aesthetics: Irene, again SM does a good job improving overall visuals for people who were naturally attractive
profit: Jungkook - he had a significant following since he was young but his upgraded visual multiplied his appeal and made him one of the biggest male soloists
4th gen - aesthetics: Sullyoon, went from pretty to super pretty
profit: Winter, was really life changing for her otherwise she would have been another Luna or Wendy
5th gen - aesthetics: Yooyeon, slight tweaks that had a big effect, but she should avoid more ps to not go deep into Gangnam territory
profit: Wonbin, i think a similar case to Winter
