Revision surgery was done over the same scars - what needs to be done to improve the appearance? (photos

I'm a white female in my mid 30's. After having a child after I had my first breast augmentation I wasn't happy any longer with the appearance of them. After my divorce years later, I decided to get them redone again. I went to the same dr. who suggested A-profile implants and I went from a C to DD. I explained that I was worried about going over the same scars, but was told because I was getting silicon again under my breast is the only place they can be inserted. what happened?
