I'm worried about my sagging jawline.

Hello. I've been having a lot of trouble with my sagging jawline lately, so I'm contacting you.

I don't think it was like this when I was young, but at some point, whenever I take a picture or look in the mirror, I see my sagging jawline and it stresses me out.

Is this what they call bulldog killing?

Do things like fillers without a chin help?

I don't think there's a way to fix sagging jawline at home. What kind of treatment would help?

And I'm also curious about the causes of sagging jawline.
