I would like to inquire about the effects of leg lifting!

Hello. At some point, my double chin and deep cheek fat started sagging, and I'm worried about it. My facial contours are a mess, too.
I have an important event coming up, so I am looking into a lifting procedure that can quickly refine my facial contours without redness or marks.
I searched online and found that many people recommend Ondari Lifting, saying that it causes minimal irritation even immediately after the procedure and is virtually unnoticeable.
I saw reviews from people around me saying that the effects of Ondari Lifting, such as line definition and improved elasticity, appear immediately.
I am curious if the effects of the leg lifting are felt immediately on the same day after the procedure, or if it takes a few days for the collagen to build up and the lines to become defined.
I am curious if there is a significant difference in terms of effectiveness and duration of results when compared to existing lifting devices! I would also like to know if the satisfaction level with On-Da Lifting is truly high, considering it is painless.
