Why didn't lasers work on thread veins around my nose?

The type of laser, settings, and person running the machine play a big component to the results you get . I suggest going to a laser expert for treatment.  Best, Dr. Emer.

I use several different lasers for veins on the nose, including pulsed dye laser, BBL/IPL, and 940 nm laser to trace out individual veins.  The choice of laser depends on several factors, including the size and color of the vein and the patient's skin type.  Veins on the nose (especially on the ala or the lower sides of the nose) can be stubborn and sometimes recur after treatment.  Pulsed dye laser usually works for stubborn veins but there is brusing afterwards which lasts for about a week.  Fraxel laser would not be expected to improve veins.  Make sure that you are seeing a doctor with extensive experience using lasers.
