Long, narrow gaunt face. Will fillers fix it?

I am a 26yo male and I have a long and very narrow face. I have always had a gaunt face, maybe because of not meeting my required calories or its just genes. Under the sun and some lights my face appears very gaunt and I would like a fuller and generally wider face. I do not want to get a surgery so would fillers help me get the look I am looking for? What kind of filler would best suite me, how many would I need and where exactly in the face?
