For Jubelook, is it okay to apply it only to the necessary areas rather than the entire face?

I am looking into Juvelook because of my pores and skin texture.

But do I have to do the whole face?
I'm wondering if it's okay to focus only on the areas I'm particularly concerned about, like the sides of my nose or my cheeks.

Those who received it partially
I also want to know if there was a noticeable difference compared to the full procedure.

Since it's my first time, I'm hesitant to make it too wide.
I'm curious about the experiences of those who have had it done on different body parts.
