My face gets very red due to nervousness and/or embarrassment. Will Pulsed Dye Laser surgery help?

I find that pulsed dye laser is extremely useful for flushing and blushing. 
The physiologic response of flushing cannot be stopped completely, but with pulsed dye laser treatments, the flushing response results in less redness. Maintenance treatments are needed after results are obtained. My patients usually have one or two treatments a year to keep the redness managed. Best wishes, Dr. Sawyer

You're describing flushing which can commonly exacerbate with heat, emotions, caffeinated beverages, cheese, spicy foods and alcohol.  Avoiding these instigators can help.  VBeam or PDL and BBLare good choices for shrinking the blood vessels which dilate with the above instigators and can hence reduce the flushing issue.  We have also anecdotally found Fraxel laser, Venus Viva and Microneedling to help with this situation.  Combined with PRP is even better as PRP helps support vascular health and all procedures help to stimulate new collagen growth in the skin.
