Bottom of breast not rounding out. Will my skin stretch with time? (Photo)

Thanks for your question! It is very difficult to answer without your before pictures or a photo of the other side. It appears your implant is located at the base of your breast, but your breast tissue does have some ptosis on top of it. Considering all of the limitations with pictures (mentioned above) I would encourage you to be patient. I think there will continue to be further softening and descent of the implant position on this breast augmentation result. Best of luck!

Your story and photograph makes me wonder if the right implant has been released enough to drop into the bottom of the pocket. With pressure on a scar, such as what's happening on the left, the scar tends to mature faster and  thin out more quickly. If the right capsule feels more tight than some degree of capsular contracture may be at play. After three months, I would recommend, if you are my patient, that some consideration be given to do a small touch up to drop the right implant. Discuss with your chosen plastic surgeon. Best of luck.
