I saw a post saying that Ondari Lifting is good. Are you satisfied?

At some point, even when I hold my head up straight, the sharp angle that used to drop cleanly from my jawline below my ears to my chin disappeared. The skin under my chin has sagged like a pouch, making it look almost connected to my neck. When I take ID photos or profile pictures, the boundary of my jawline is blurry, making my face look much puffier. When I touch under my chin, it feels like the skin itself is being dragged down limply. Even after dieting and losing weight, strangely enough, this sagging skin under my chin doesn't adhere firmly to the bone and just seems to move independently. I saw a post saying that Ondari Lifting is good for tightening sagging skin from the inside. For those of you concerned about the blurred angle between your jaw and neck like me, are you satisfied with the procedure?
