My face line has sagged and my jawline has sagged. How do you manage it?

These days, I'm always surprised when I look in the mirror every morning. My side profile used to be quite smooth, but at some point, I started to feel my face sagging. I'd even get really upset when I unconsciously lowered my head in brightly lit places and saw myself reflected on the screen. My sagging jawline was especially noticeable. Once I started to care about it, I couldn't stop looking in the mirror when I went out, and I even developed the habit of resting my chin on my hand. I tried using the best cosmetics and even massaged my face with care, but my sagging jawline was already there. It's not easy to manage this area. Even in photos I take with friends, I seem to be the only one showing the signs of aging, and my confidence isn't what it used to be. I've been searching for ways to restore my elasticity, but do I really need the help of a professional? I'm really curious to know how you manage your sagging jawline, which is particularly noticeable. Could you share any special methods or massage tips you've found effective?
