Swelling, 8 days post BA, when should I expect them to go down? (photo)

At 8 days you are about 5 percent healed, settled, shaped, softened, dropped and fluffed. When concerned always a good idea to check in with your surgeon. "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.

Hello. Thank you for your inquiry and congratulations on your surgery!
It is important to have an in-person medical assessment regarding this issue as it is difficult to determine virtually. Continue to update your doctor in the matter and follow their post-op protocol.
It is important to get cleared by your doctor before engaging in specific physical activity before the 3 month healing period has ended as the healing stage is crucial for healthy results.
It generally takes around 6 months to a year to see your final results. Your tissues will take time to relax and allow your implants to "Drop and Fluff" settling into place.
Our tips for recovery following breast augmentation are to wear a supportive sports bra for 3 months post-operative and refrain from lifting anything heavier than 10 lbs for 3 weeks as we don't want any strain at your incision sites. Make sure to keep the area of your stitches clean by cleansing with hydrogen peroxide daily. Showering is encouraged! But, no sitting in water for 2 weeks following surgery (no baths, hot tubs, pools etc.).
