I have narrow upper lip. I want outer sides hidden in my mouth outside and make wider upper lip. Any suggestion?

My upper lip curves like Elvis lip on both sides-like sneering when I am talking. My teeth is showing so little when I smile so it is not an option to do botox on superior labii levator muscles. when I raise outer edges of upper lip it fixes. like liv tyler lip and ı like that look. what should be done? is it possible to shorten zygomatic majör, minor and levator anguli oris ? ı want to hang it like i do with my fingers. before doing it should the edges be cut a little like korean smile surgery?
