My jawline has become less defined since entering my 30s; will Shurink be effective for me?

It seems like my facial contours stayed distinct until my late 20s without any special care, but since entering my 30s, I can feel my skin elasticity dropping noticeably.

I am particularly concerned because the swelling in my face doesn't go down easily when I wake up in the morning, and when I look in the mirror, my jawline doesn't feel as sharp as it used to and seems to be sagging slightly. It isn't severely sagging, but I can see a subtle double chin and my cheek lines collapsing, so I am looking into laser lifting.

Among lifting procedures, I am considering Shurink first because it is said to be accessible and easy to get started with. However, now that I am actually about to get it, I am concerned whether I can see a definite line correction or lifting effect despite the loss of skin elasticity in my 30s.

Has anyone else in their 30s had Shurink treatment like me? I am wondering if 300 or 400 shots would provide satisfactory results for fine lines and jawline refinement, or if it would be better to combine it with other procedures like Ulthera or InMode. It would be a great help in making my decision if you could share honest reviews or tips from those in their 30s who have had the treatment!
