I'm considering a double chin lift. How effective is it?

Hello. As I get older, even though I haven't gained much weight, the skin under my chin is sagging and it looks like a double chin, so it is bothering me. My profile looks very different in photos compared to before, so I have been looking into double chin lifting lately.

If anyone has had a double chin lift, I am curious if it actually refines the chin line. I would also like to know if the effects are visible immediately after the procedure and how long the results last.

I am looking for a natural refinement of my jawline rather than a drastic change. I am also curious if women in their 50s generally have a good level of satisfaction, and I would appreciate honest reviews from those who have undergone double chin lifting. Thank you. Please share your experiences with double chin lifting.
