My cheeks are sagging and I've lost a lot of elasticity. Will the Denser-T lifting be painful? ㅠㅠ

These days, I can really feel my skin barrier thinning with every fiber of my being as I get older. When I look in the mirror, my jawline seems to be sagging slightly, and the jowls around my mouth are sticking out. It makes me feel depressed and upset because I look old even when I'm just standing still. I don't think contouring injections will solve the sagging skin issue, so I'm seriously looking into the radiofrequency Density Lift, which is said to tighten both the surface and the inner layers of the skin simultaneously! Everyone highly recommends it, saying it's less painful and safely shapes the jawline. However, my skin is on the thinner side; can someone like me really get a V-line lift without worrying about side effects like sunken cheeks? I'm scared about whether the bruising or swelling will last a long time. Beauty veterans who have had amazing lifting treatments, please share all your tips!
