How long until redness and bruising subside after nasal fillers?

Your question is difficult to answer without a picture. Though, redness and bruising can be seen after filler injections, the nose is an area which is at risk for vascular compromise after filler injections. The best thing to do is see your injector ASAP for an in-person examination. Best wishes.

It's too soon to tell what your final results will be. I recommend following up with your Doctor for a formal evaluation and after care recommendations if you're concerned. Swelling can last 1-2 weeks after filler injections. If you're unhappy with your final results, you can have it reversed with hyaluronidase and try a different technique next time. See an expert. Best, Dr. Emer

Bruising is typical after injections and usually resolves before two weeks.  Redness at the time of injection is common, but that should resolve after a few hours.  I would contact your injector regarding redness that has persisted this long.
