I'm talking about leg lifting. Does a painless and effective procedure really exist?

I am someone who almost gave up halfway through last year, tearing at my pillow and sobbing uncontrollably while getting hit with something. I can see my jawline sagging, so I know I need to get a lift again, but I simply can't bring myself to go through that bone-pounding pain again. After asking around, I found out about On-Da Lifting, which is said to be so comfortable that you don't even need anesthetic cream. But seriously, does a painless, effective procedure really exist? Honestly, I have this fixed idea that it has to be painful to be effective, so I'm skeptical that On-Da Lifting might just be an expensive heat massage. I'm a total wimp who hates pain, so those of you who have tried On-Da Lifting, please give me some honest, harsh truths on whether your jawline really tightens up without any pain.
