Hiya, I'm not personally much into birds and know nothing about them - posting this all on behalf of a non-internet-savvy friend!
She has a lovebird which started out with a small bump just above its beak, started treating it for... something to do with mites, can't remember off the top of my head, but over the last couple of weeks it's started to spread down the beak and the treatment doesn't seem to have made a difference. Starting to wonder if it might be something bacterial perhaps? Apologies for not being too clear - as I say I have no clue when it comes to birds! Hopefully the photo is clear enough.
