I keep feeling like my jawline has become blurred.

Lately, every time I look in the mirror, I keep feeling like my jawline is becoming blurry.
I haven't lost weight, but my face feels strangely saggy, so I'm looking into lifting procedures. However, there are so many types that I can't quite figure out which one to choose.

I've heard that thread lifting is good, and that many people get Shurink or Ultherapy, but considering the pain and the duration of the results, I can't readily make a decision.

If someone is getting a lifting procedure for the first time, which procedure would be less burdensome to start with?
