Four years post deep plane facelift and I can’t get my smile back. Will a lip lift help? (Photo)

I had a deep plane facelift and neck lift 4 years ago. Immediately after the surgery I could see that my right side of my face had dropped. I was told no nerves were cut but they had been stretched. After dozens of facial physio treatments, acupuncture, Botox my smile is still uneven and my teeth don’t show anywhere like they used to. It’s making me very sad. I’ve been told a lip lift will help to show more teeth? My lips are symmetrical when at rest it’s when I smile they are crooked.
