3 months after nonsurgical nose job, nose is still red - should I be concerned about possible necrosis? (photos)

Your nasal tip certainly appears quite red. This can happen when too much filler is placed into a small area. Do you know how much volume was used? Does your nasal tip look improved with the filler as compared to before? If you have an improved tip appearance, you might consider IPL treatments to reduce the redness. If your nose is suffering from inflammation with variation in swelling and discomfort, this may not be a good idea. If your current physician cannot help you, please get a second opinion. I hope this is helpful. Sincerely, Dr Joseph
