Will Bruising After Blepharoplasty Go Away?

The degree and duration
after blepharoplasty varies from patient to patient and technique to
technique. Bruising will always go
away. A bruise is the result of
blood trapped in the tissues under the skin. Over time, this blood is broken down and the components
reabsorbed into your system.

Most bruising, if it's true bruising, will all eventually go away. Sometimes there are pigments in your skin that was not noticed before surgery and now you just started seeing it, and those pigments won't likely go away. but if you are only one month after surgery, I recommend waiting longer first.

This question should be presented to the surgeon who performed your operation.  "Bruising" is the common term equivalent for "ecchymosis," blood clot (hemoglobin) beneath the skin that is visible on the skin as violet-blue-dark red coloration.  Darkness may indeed be related to hemosiderin (breakdown product of hemoglobin), post-inflammatory hyperpigmentation, swelling with fine wrinkles and resulting shadows, some combination of these, or something else.  What will happen to that coloration over time depends on what it is, and your surgeon would know, based on your skin type, on his/her technique, and on the type of blepharoplasty you had.
