Removing "nipping" if possible on re-augmentation? (photos)

I currently have 12 year old 260cc high profile implants that are being replaced soon. I will be going a little larger but have been very happy with the results and would only change one thing that appeared a little more over time but was there after the initial swelling had gone and the implant had settled over the muscle. The little nips or tucks that are visible by my armpits, what would need to be done to ensure the breast was full and rounded at that point rather than appearing nipped? TY
