What can I do about my sagging jawline that worries me every time I look in the mirror?

These days, every time I wake up and look in the mirror, I'm deeply concerned about the drastically different facial contour. Before, a quick wash and basic skincare routine seemed smooth, but now, whenever I look at my profile, I notice my sagging jawline. Seeing the shadows cast by the light really shows how much elasticity I've lost, and it's frustrating. Especially after taking pictures with friends, it's hard to see the original without using a retouching app. I used to rarely reshape my face, but now, sculpting my jawline has become a necessity. I regret neglecting my skincare routine in the past, and I'm looking into home care devices because I feel like it's not too late. No matter how good my makeup is, it feels like my sagging jawline is difficult to resolve, which is even more frustrating. People around me recommend lifting bands or massage devices, but I'm curious to know if anyone has actually seen results. Or is a procedure the fastest way? If you have any helpful tips for simple massage techniques or lifestyle habits that you can practice at home, please share them. Rather than feeling depressed by the sagging jawline in the mirror, I'm writing this post to proactively find a solution. How do you manage it?
