Stretch marks

Im seventeen years old (senior is highschool) and I have been struggling with stretch marks on my breast. I understand that my breast grew too fast(I was A cup in middle school then Freshmen year I was D) and I was able to reduce the lighter scars and the dark color on the deeper stretch marks. However, they have came back and some are darker than before. Do you ladies have ideas or remedies that can lessen the appearance or get rid of them?
