Did Ok Joo-hyun have liposuction surgery?

If you look at old photos, her face was particularly chubby and her body was chubby... She looked really healthy during Fin.K.L's first album, but after that, her body looked slim, probably because she went on a diet. So, I think she must have had liposuction or something like that. Ock Joo Hyun is very. Since she has been fat for a long time, it is difficult to change her constitution, so I think she must have had some surgery to remove the fat and then exercised to tone her body. If you look at Ock Joo-hyeon these days, she has a slim face. Of course, she looks slim because she had facial contouring, but she also lost weight . I think that's why the line around her neck looks pretty. Did Ock Joo-hyun get liposuction around her neck too? ;;;;;
