How long can bruising from a filler last?
It really sounds like you did everything you could to prevent bruising. A few small to medium sized bruises that last a few days to a week or so are considered normal. But 6 weeks later? This doesn’t make sense to me.
You didn’t tell me which filler was used. If the filler was a hyaluronic acid filler like Juvederm or Restylane, then it’s time to consider that it might have been placed too superficially in the dermis, which will result in a bluish discoloration which doesn’t go away. It’s sometimes called the Tindall effect. If it’s a placement problem, the filler should be removed with hyaluronidase and redone a week or two later, in my opinion, at no extra cost to you.
Please go back to your provider – hopefully a board certified dermatologist or plastic surgeon, or a very experienced RN in their office, and see what their evaluation is.
Hope this helps, Dr. I
