Best Treatment for sun damage and discoloration under eyes, fine wrinkles and brown discoloration around mouth? (photo)

I am 34 years old and have developed a lot of sun damage discoloration under my eyes and on my cheek bones that is really starting to accentuate my already dark blue/purple tear trough areas. I also have some brown patches around my mouth that I think might be a type of melasma & some fine wrinkles under my eyes. What is the best treatment for these? The biggest thing that, bothers me is the under-eye tear trough area because I think it makes me look tired and ill if I don't have makeup on.
