What is the best procedure to deal with pigmented lips and bacne spots? (photos)

I have dark lips since 12 years old and prone to skin sensitivity from a very young age too. Used to have clear yellowish complexion but it became dull with age. I do have clear facial skin though. But my lips have darkend a lot. I do smoke very occasionally. My bacne problem occurred in 2014 few days after I got a professional waxing done for hair removal. Small pimples appeared but now it's gone and left hideous marks behind. I'm very embarrassed to wear backless or go out without lipstick.
