Does the impression of a person change more than expected depending on where fillers are injected into the face?

When I look at my recent photos, one side of my cheek or temple looks a bit sunken, so I am thinking about getting fillers.
But I don't plan on adding much; I just want to improve it a little bit. 😊

Can the impression of a face change significantly depending on where the filler is injected, even with the same amount?
