What procedures can I do to fix my asymmetrical face? (photo)

I want to know what are procedures that could be done to my asymmetrical face, mostly right side of my face from being droopy. My lip slants down so much and so does my eye, it becomes very obvious when I have pictures taken that my face is droopy on one side. I’m not trying to get Botox or filler because I don’t want to end up with pillow face years later. I also don’t want to add anything in my face that’s going to make it look fat. And I am young only 20 years old.
