I am in my mid-40s and my jawline is sagging and I have a double chin. Which consultation would be right for me among InMode, Shrink Universe, and Density?

I am 47 this year, and lately, every time I look in the mirror, I feel upset because my face doesn't look as sharp as it used to. The boundary of my jawline has become blurry, and when I lower my head, the skin under my chin folds, making the line leading to my neck look messy. I haven't gained much weight, but my cheeks feel like they have sagged. I look fine in the morning, but by the afternoon, I look much more swollen, so I end up avoiding taking photos.

Since this is my first dermatology consultation, I am unsure where to begin, so I have a few questions. First, if my main concern is sagging rather than weight gain, I would like to know which procedure among InMode, Shurink Universe, and Dencerty is the right fit, and if combining multiple treatments is common practice. Second, I understand that the treatment method varies depending on whether the double chin is due to fat or sagging skin; I would like to know if this can be confirmed via ultrasound during the consultation. Third, as I am in my late 40s, I am concerned about side effects such as sunken cheeks or further skin sagging. Fourth, since I work, I would like to know if swelling and bruising subside within a week, and what is the appropriate interval between treatments.

Given the cost, I would feel burdened if I were recommended multiple items at once. I would appreciate it if you could let me know if there are any specific things I should prepare or check before the consultation.
