Breast Reduction from 500cc to 400cc?

Photos are important but a physical exam will be decisive. A 40 cc reduction in implant size will not make a difference. It is impossible to say whether going smaller than that will result in significant sagging. Another issue is whether the problem is size alone or the profile of the implant.

In order to see a significant change in breast size, it is likely that you will need to downsize breast implants at least 100 mL. In other words, the change of 40 mL may be a waste of your time/efforts.

 Whether or not additional breast lifting will be necessary, will depend on your physical examination. As you know, if you end up with loose/"sagging" skin after the downsizing of breast implant procedure, the overlying skin “envelope” will need to be tightened. You may want to give your plastic surgeon  your consent to revise your breast lift if necessary, at the time when you undergo downsizing of breast implants.

 I hope this, and attach link, helps you as you learn more about revisionary breast surgery.

Best wishes.

If you really think your breast implants are too large reducing them by 40 to 100 mL doesn't make much sense. They really will be that much of a
