Im going swimming in two weeks and you have a bikini how do you get rid of dark spots on your back above your butt and under your eyes?

The main problem here is the poor grammar and lack of punctuation. You're going swimming and I have a bikini??? I don't have any dark spots on my back, above my butt, of which I am aware. Nor do I have dark spots under my eyes, but what would this have to do with the bikini that I don't have, and the fact that you plan to go swimming in two weeks? The best that I can suggest is evening classes in English as a second language at a local community college.
