Is it okay to get Shrink done only on the necessary areas rather than the whole face?

I am looking into lifting procedures for the first time, but I am confused about whether I need to have my whole face treated or just the areas I am concerned about.

I tend to only be concerned about the area under my chin and around my mouth, so I'm wondering if it's really necessary to treat my whole face.

However, I’ve heard that doing it partially might make the overall facial contours look awkward, so it’s hard to make a decision right away.

I understand that the hospital would be the most accurate in determining the best course of action based on my facial condition, but I would like to know how others handled this before the consultation.

For those who received Shurink primarily on the areas that needed it, how satisfied were you?
