I have noticed that I have facial asymmetry, especially in my lips. What is the best way to proceed?

My cheekbones are asymmetrical along with my eyes. I have had braces in the past, but have not worn my retainers since. I'm concerned this is more of a jaw issue. Anyways, my biggest conern is my lips, which look very off and asymetrical. I am wondering what is the best, permanent solution with low risks to fix this issue. Thank you
