How long does the double chin lifting effect last?

Lately, whenever I take a photo, I am very worried because my jawline doesn't look the same as it used to.

So I am looking into double chin lifting procedures.

I am especially curious about how long the effects of a double chin lift last.

I looked it up and found that there are various types of double chin lifts.

I heard that there are also high-frequency and ultrasonic methods.

For those of you who have actually received a double chin lift, how satisfied were you?

I am also curious if I can feel a change immediately after the procedure.

I would also like to know how many months the double chin lifting effect lasts.

I am curious about the average duration of maintenance, although it may vary from person to person.

If additional procedures are needed, please let me know the intervals at which they should be received.

I am also curious about the extent of the pain.

I would also like to know if the swelling or bruising tends to last a long time after the procedure.

If the satisfaction is high compared to the cost, I would like to try it.

We would appreciate honest reviews from those who have actually experienced this.

Thank you in advance for your reply.
