How to fix a long philtrum and protruding lips/mouth? (photos)

I feel as though my facial features are not in balance and are not attractive. I have a small, short nose and a long upper lip that protrudes beyond my nose and chin. I really desire a more attractive facial frontal view and profile view. I was told that I could benefit from a chin implant, but I am more concerned with my mouth area more so than my nose and chin. I really want my lips to lay flatter in proportion to my nose and chin, but still be nice and full. What could I do to fix the issue?
