I had closed rhinoplasty surgery around 5 months ago and I still have visible dark circles under both eyes which weren't there pre op. Could this be permanent? Is there anything I can do to get rid of them? I had a bad reaction to Arnica so had to stop using it. The bruising was quite bad after surgery but got progressively better up until around 2 months ago, since then I have seen no further improvement so am worried that this is permanent now.
