I'm curious about the effects of Ondari Lifting!
I was concerned about my facial contours sagging, so I became interested in On-Da Lifting because I heard it uses microwaves and is minimally painful. I am interested because it is said to be different from conventional ultrasound or radio frequency methods, but I am leaving this question to ask about the actual effectiveness of On-Da Lifting. I tend to be sensitive to pain, so procedures like Ulthera are daunting for me, but I heard that On-Da Lifting can be received comfortably thanks to its cooling system.

However, I am concerned that even if the pain is minimal, On-Da Lifting would be meaningless if the effects are negligible. I have seen reviews stating that On-Da Lifting is particularly effective on areas with excess fat, such as the double chin or deep cheeks; how long after the procedure can I expect to feel noticeable tightening? I would also like to know how many sessions are typically required for long-term improvement. I am looking forward to it since it is said to help regenerate collagen deep within the skin, but please let me know how long the effects of On-Da Lifting typically last compared to other lifting procedures!
