Oranges Stretch Marks Do My Breasts Have Stretch Marks On Them?

Do my breasts have stretch marks on them? - oranges stretch marks

I am 13 years old and a C cup since I was a B-cup, I noticed a line of reddish purple outside. I think they are stretch marks, but I do not know. Me too, and orange / brown like bruising on the head. What is it and how do I get rid? Nothing can at home, perhaps a lotion that I buy to get rid of them without irritation? Thank you!
