I'm curious about the lifting effect for sagging under the chin.

Lately, it feels like my jawline has sagged a lot more than before.
I haven't gained a lot of weight, but it bothered me because the area under my chin looked folded even when I lowered my head just a little.

It is especially noticeable in side profile photos, so it makes me feel like I look older than my age.
I am wondering if these areas can also be improved with lifting procedures like Shurink or InMode.

Is it the case that changes are visible even after just one session?
Or I would like to know if I need to receive it consistently to maintain it.
I'm also curious about the extent of pain or swelling.
Lately, even lifting creams or bandage devices aren't working, so I'm wondering if washing is the only answer.
