Sagging jawline that is noticeably noticeable in the mirror

Man, I hate looking in the mirror every morning when I shave these days.

I used to hear people say that I had a sharp jawline when I went somewhere. But what's this? At some point,

You can see that the facial lines are just collapsing. Especially when I bend my head down while working, my jawline starts to sag.

It's thick and sticky, but it's really awkward to look at.

These days, when I look at myself on the video camera during business meetings, my sagging jawline catches my eye.

I can't concentrate at all. It feels like everyone is just looking at my chin... I go to the gym to take care of my health.

I'm trying to lose weight and eat less, but this damn fat on my face just won't go away.

Now I really need to do something or apply something. I feel like this can't go on like this, so I'm posting this with a desperate heart.

How do other older brothers and younger brothers manage their sagging jawline? How can I manage it without making myself look awkward?

Are there any lifting products that I can use quickly, or effective massage techniques that I can do at home while watching TV?

Please share some practical tips to help me get back to even half of my former, resilient state. I'd appreciate it if you could share some advice, mixed with your own experience, on how you all manage it!
