My skin has lost elasticity and my cheeks are sagging slightly. Will the ultrasound lifting be painful? ㅠㅠ

I took a super close-up shot of my skin, and as I get older, my skin thins out, my overall elasticity drops drastically, and I can actually see my jawline and cheeks sagging slightly. ㅠㅠ It’s not like I’ve gained any weight, but my facial contours look dull, and every time I look in the mirror, I feel like I look incredibly old; it feels like I’m going to get depression. Haha. I’ve heard that ultrasound lifting machines, which pull the skin from the deep fascial layer rather than just the surface, are so good. If someone like me, who has lost elasticity, gets them, will my face be lifted up to a V-line? I heard it hurts so much when they shoot at the jawline that it feels like your bones are tingling. I’m really curious if I can just grit my teeth and endure it with only numbing cream without general anesthesia, and if there are any side effects like hollowing out the cheeks. ㅠㅠ Please leave some tips for those of you who have had lifting lasers and found your skin firmer! ㅋㅋ
