Would a Lip Lift Help Tooth Show and Asymmetric Lips?

I'm 21 and considering a lip lift, I have researched a lot on it but am still unsure. I have little "tooth-show", and the right side of my lip is slightly "higher" than the other side, making my lips somewhat lopsided. I always notice it in photos and hate how it looks. My theory is that the muscle on the left side is weaker, and therefore more "droopy." Could that be corrected? Would a lip lift help me out? Thank you.
