How effective can I expect a double chin lift?

Hello. I am an office worker in my 30s.

My facial contours used to be relatively distinct, but recently, it makes me sad because the skin under my chin looks saggy when I take photos or video call. Even though I haven't gained much weight, my double chin looks prominent, so while looking into ways to manage it, I became interested in double chin lifting.

I have read that double chin lifting can help refine the jawline and create a smoother facial contour, but I am curious about the actual effectiveness I can expect. In particular, I would like to know if the satisfaction rate is high even for those in their 30s, a time when skin elasticity begins to gradually decline.

I would also like to inquire whether changes from a double chin lift are visible immediately after the procedure or if the improvement occurs gradually over time. I am also curious about the pain, swelling, and the recovery period for returning to daily life.

Since it is usually difficult for me to make time due to work, I would like to know how long the procedure takes and whether a single session is sufficient or if multiple sessions are required. Please also explain the duration of the double chin lift effect and the recommended treatment cycle.

Finally, I would appreciate it if you could provide detailed information on whether a double chin lift is a suitable option for someone in their 30s like me, whose jawline has become blurred and who is starting to worry about a double chin, as well as who is recommended to undergo the procedure and what precautions to take. Thank you!
