Is it okay to receive Volneumer only on the necessary areas rather than the entire face?

While looking into lifting procedures, I found that there are cases where the entire face is treated at once.
I've noticed that some people focus only on problem areas like their jawline or cheeks.

I don't feel like it's sagging overall, though.
When I take photos, my jawline looks particularly blurry, so that's the only part that bothers me.

Rather than unconditionally treating the entire face
I am wondering if it is a good idea to consult first about the specific areas of concern to determine the scope.
