Will my breast implants fluff and drop? I recently got dual plane, 550cc saline breast implants. (Photos)

"Drop and fluff" refers to the fact that as the skin stretches and the muscles relax, the implants move down and out slowly – about 1 percent a day. It’ll be about six weeks before they even begin to settle down, but they’ll be close to 80 percent settled and softened at three months. Watching their progress is like watching your hair grow. You don’t see a difference in your hair growth daily, but all of a sudden you need a haircut. 
Be patient after surgery. Give yourself a few months before making a judgment about your surgical results. You won't know the outcome until then. Your increased volume will make it easier to push your breasts closer in clothes.

Thank you for sharing your question and photographs and congratulations on your breast augmentation.  Initially after surgery the swelling in your breast skin and underlying muscle causes the implants to appear wide and high against your chest.  As this swelling resolves you should see the silicone gel redistribute within the implant into the lower portion of each breast giving you a more natural appearance (drop and fluff).  This typically occurs in the 6-8 week range.  I know it is difficult but hang in there and allow your results more time to mature. 

You did not share with us how far out from surgery you are but if you were my patient and this were your appearance a week or so after surgery, I would recommend to you to wear an elastic upper bandeau 24/7 for a week or two or three. Please discuss your concerns with your plastic surgeon and do not consider this email as "advice". Any recommendations made in this forum should be discussed and supervised by your surgeon who knows best exactly what operation you had done. Best of luck to you.
