I'm not 100% sure, but I think Yoona and Seohyun haven't done it. Taeyeon is also most likely natural. Yuri only did eyelid surgery, Sooyoung changed her jaw, and Sunny got a nose job and did something to her eyes. Hyoyeon, Tiffany, and Jessica had a ton of work done.
I think all 8 has surgery because if anda compare them to the older foto and video anda can see things change in times...its not that big changes but anda can see what has done on the girls...and the one who doesnt got surgery is the youngest one, Seohyun has exacly same face since she was a child...and i think shes the kind of person that doesnt want change things on her look :)
1. Taeyeon - Double-Eyelid Surgery and Nose Job/ Rhinoplasty 2. Jessica - V-Line Jaw Reshaping and Nose Job/ Rhinoplasty 3. Sunny - Double-Eyelid Surgery 4. Tiffany - Double-Eyelid Surgery and Nose Job/ Rhinoplasty 5. Hyoyeon - Double-Eyelid Sugery and Nose Job/ Rhinoplasty 6. Yuri - Double-Eyelid Surgery 7. Sooyoung - Nose Job/ Rhinoplasty 8. Yoona - V-Line Jaw Reshaping and did Nose Job/ Rhinoplasty two times.
Actually . What i feel is snsd never do a plastic surgery . They can change oleh doing an exercise , diet and growing older. anda try to look ur pic when your aged was 10 or12 im sure thats super diff . Like me i also hav a lots of diff . All my friends thought that i do a plastic surgery but i didnt do . It was just because im growing older and my looked change :) . For me i always do an exercise and diet . Maybe bcause of that i became lebih diff . And guess what my skin tone bcome lebih whiter than bfore. Last time my skin lebih darker . The color was like a coffee . lol . But its true . Dont judge a book oleh its cover :)
