Can changing just one part of the face change the overall impression of the face?

The side of my nose looks a bit sunken, so I'm looking into fillers.
I'm actually a bit worried about whether I only need to fill in one spot.

I just want that specific part to improve naturally.
I'm worried that I might end up worrying about other things for no reason 🤔

Did you go for the initial consultation with just one specific area in mind?
