I want to refine my jawline. How cost-effective is jaw thread lifting?

My jawline has become much less defined than before, and I have a double chin.

In particular, the skin under the chin sags slightly, making the face look dull overall, and the face shape doesn't come out nicely in photos.

My skin isn't severely sagging, but the line from my chin to the sides isn't smooth, so I'd like to get some treatment.

While researching various procedures, I learned about jaw thread lifting. I understand it is a method that uses threads to pull up sagging skin, and I am curious about how the effects differ compared to standard laser lifting. Will I see noticeable changes if I only receive treatment focusing on the jawline?

However, the cost of the procedure is a burden, so I am looking for options that offer good value for money rather than simply opting for the most expensive treatment. It seems there is a significant price difference depending on the number of threads used, so please let me know how many threads would be appropriate for a first-timer. I would prefer to receive the procedure with only the necessary number of threads, rather than having as many threads inserted as possible.

I am also curious about the level of pain, bruising, and swelling associated with thread lifting. Please let me know if I can resume my daily activities immediately after the procedure, and how long the effects typically last.
