How to lighten tattoo on lower back is that is to dark on African American skin?

I am AA not to dark pretty fair toned. I have a fairly month old tattoo on my lower back that is a cover up but it is so unrecognizable and dark. Is there anything I can do? or the artist can do? I was told some artist aren't good with either AA skin or cover ups that she may have scared me for than anything. But this is a well known tattoo place full of professionals.
