I would like to inquire about the price and effectiveness of leg lifting.

Lately, my skin feels like it has lost a lot of elasticity and is sagging, so after much consideration, I am planning to get a leg lifting procedure. I tried managing it on my own using only cosmetics and home care, but I felt like I had reached my limit and wasn't seeing any improvement, so I thought it would be right to get professional help.
I have a few questions. I would like to know the approximate cost of the On-Da Lifting procedure. I am curious if there is a significant price difference depending on the area treated or the type of tip used. Also, for those who have received On-Da Lifting, I would appreciate it if you could share your reviews on how many sessions are typically required to see noticeable results.
I am planning to get consistent care on schedule, so if anyone knows about this, please give me some advice.
