Bruises 4 weeks after breast augmentation surgery? (Photo)

From the photograph you sent of your excellent breast augmentation, I seriously doubt at this point that you have a problem.Small blood collections (non hematomas) in the subcutaneous tissue often take weeks to migrate to the skin.  Since the migrations usually occur downward and not upward because of gravity and the normal flow of lymphatics in that part of the body, I suspect you have delayed bruising to the upper part of your breasts.  This bruising in my experience takes a long time to dissipate.  If you were my patient, I would treat this bruising with topical DMSO which opens choke vessels leading to an increased number of white blood cells to any given area which hastens the elimination of bruises.  I highly recommend you discuss your concerns with your personal plastic surgeon.

Bruising is normal and to be expected following any surgery.  Some individuals have no bruising, some have a little, and some have quite a bit; it is unpredictable. Bruising from the tape appears to be dissipating.  If it does not fade within a few days, phone your plastic surgeon's office.

Your results look great.  The bruises are turning yellow which is the final phase of your body destroying the red blood cells.  This phase usually takes about 1 week before you see an improvement.   If you left it alone, you will see improvements over the next week or so.    I find that massaging and using warm compresses helps to speed up the process.
