I have a double chin and a prominent chin.. First of all, because I don't have a chin, when I gain weight, my double chin gets worse and my side profile looks unusually round and flat. If you don't have a chin, you definitely have to have a thin face to look more human, right? It really looks like my face will roll around ㅠㅠㅠㅠ Even if I get filler for my chin, I still have a chin..
