Are there changes in the effects of the leg lifting immediately after the procedure?

I am considering a leg lift and I am wondering when the effects will appear after the procedure.

Does your facial contour become more defined or your jawline gradually become smoother right after the procedure?

Or is it a method where skin elasticity improves and the jawline gradually becomes more defined over time?

I am also curious if there is a difference in the effects between immediately after the procedure and about 2 to 4 weeks later, although there may be individual differences.

For those who have actually received the treatment, please share your experiences regarding how much time passed and whether you noticed changes in your facial contours or elasticity.
