I'm looking at LST and JST, and please recommend some good places for thread lifting as well.

My cheeks are sagging, so it feels like my face is falling apart. I was stressed because my face looked fat, so instead of going all out right away, I decided to take a gradual approach and started eating only two meals a day this year. However, since I wasn't seeing the dramatic results I expected, I even added cardio exercises. But because the results aren't matching my efforts, I'm thinking of getting a procedure done, so I'm planning on getting a thread lift. I'm not doing this on impulse; I've been thinking about it for about a month, haha. That place looked good from what I saw online, but are there any other plastic surgery clinics famous for thread lifts? It doesn't matter as long as it's within the Seoul area. Please give me some recommendations.
