Procedure to slim/feminize face shape?

How can i feminize my face a bit more? I was thinking the lower part of my face appears heavy, i am 25, however my cheeks have always looked this way since I was a young child. I I do not mind round cheeks but i would like the bottom to be more V shaped (look at last pic laying down) how can I achieve that? I am not sure if injecting masseter muscle will slim the lower half, or buccal fat removal or chin implant. I want to be cautious i do not age myself just feminize more
