I've been having a lot of trouble with my sagging jawline lately.

These days, when I look in the mirror, the first thing I notice is my sagging jawline. I haven't gained any weight, but the area under my chin feels strangely heavy and saggy, so I'm worried about it even when I take pictures.
So I'm trying hard to get rid of my sagging jawline by getting a Gua Sarang massage, but I'm not sure if it's really making a difference. I've heard that Inmode is helpful for managing sagging jawline, but is there a treatment that helps with managing sagging jawline? Please let me know if you can!
