Is there almost no pain or irritation from the Ondari Lift to refine the sagging lower jawline?

Hello! As I enter my mid-30s, I am extremely worried because the elasticity in my lower face has noticeably decreased. Even when I just tilt my head slightly, the skin under my chin folds thickly, and the dull-looking jawline makes me upset every time I look in the mirror. I had been hesitant to try conventional lifting procedures like Ulthera or Shurink because I heard they are too painful. However, while researching at Maypure City Hall Station, I learned about the Onda Lifting device, which allows for a comfortable treatment without anesthetic cream thanks to its powerful cooling system! I am really curious to know how painful Onda Lifting actually is for members who have received it. I would appreciate it if those who have experienced Onda Lifting could share their honest advice and information regarding whether the procedure is truly painless and provides a lifting effect that tightens the jawline after just one session, as well as side effects like sunken cheeks, bruising, swelling, and downtime.
