With Shurink, is there a difference even if I only use it on the jawline rather than the whole face?

I'm not really worried about my facial fat.
The blurry jawline keeps catching my eye.

So I'm looking into Shrink.

But do I have to do my whole face?
I'm not sure if it's okay to only do the necessary areas like the jawline.

If your cheek fat decreases along with it
I'm worried it might turn out the opposite of the face shape I want.

Even if you have received treatment mainly under the chin or along the jawline
I'm wondering if the lines feel organized.
