I had a chin contouring done 4 years ago and the next year
 I had a chin suction done, and my double chin area sagged like a pelican. ㅜㅜㅜ
 I think I had skin sagging rather than fat because I had a chin contouring done 3 years ago.
 In this case, will I see the effect of double chin muscle tying??
I made reservations for three consultations next week, but today I went to see the progress of the hospital where I had my nose surgery and asked about it, and the consultation director said it wouldn't be effective. So, please tell me about the experiences of those who got double chin muscles.
