Is the Blue Skin Tone Something to Be Concerned About from my Recent Breast Lift/augmentation (Image at Five Weeks Out)? (photo)

I can't say that I have seen this before, so we can only speculate on what is causing the blue tinge. It does not look like anything serious, however, as your shape and healing look perfect.

I would agree that it is most likely some blood under the skin that is breaking down and giving the color. Marking pen ink goes away right away, and would not stick around five weeks.

I think time will give the answer.  If it is blood breakdown, it should resove in a week or two.  Your surgeon who knows best about your surgery is the one to keep in touch with.

Bluish discoloration after breast surgery is usually an indication of a hematoma or collection of blood under the flaps that will migrate toward the surface after surgery.  Sometimes it may take 3 to 6 weeks for deep fluid collections to surface, and I warn my patients that the tissues will sometimes push the fluid out through the incision scars.  So, don't be alarmed if you wake one morning with stained sheets, this fluid needs to be ejected, or it my take another several weeks to absorb.  Warm compresses may help resolve your issue here.
