I have Dark spots between my breasts but darker ones underneath my breasts, I sometimes wash the dark, a little hard, flat spots on me, harder and it makes it smooth but ita still there. How can I get rid of them, and besides, I ve been trying to look for answers to get rid of them, they look embarrassing on me. They just kept getting worse. P.S they look like dirt once wet, scratching them off but if dry, kinda ictches and scratches on them.
