What treatment can I do to get permanent results on my dark upper lip moustache? (Photo)

The skin above my upper lip is dark creating a mustache effect on my face. I've never worn sunscreen that much and whenever I wax or bleach the dark upper lip mustache doesn't not go away. Even when I have no hairs on my upper lip it still looks like I have a mustache. I've done hair removal lasering and that didn't help. The picture below doesn't do justice to what I'm talking about but I don't like taking selfies because I'm self conscious about it.
