What can be done surgically or otherwise to reduce nostril flare when I smile. (Photos)

Since your nose is attached to your cheeks, when your cheeks elevate with smiling, this causes dilation of the base of the nose in everybody. If this is your only concern about your nose, I do not believe there is any non-surgical intervention to consider. Thank you for this question. Sincerely, Dr Joseph

You are describing a fairly common condition. Since the flaring of the nostrils relates to the dynamic actions of the tiny muscles controlling the wings (alae) of your nose, this can often be easily addressed via the proper placement of a couple of microdroplets of Botox to suppress the upward pull of the muscles responsible for the flaring. The two other currently available injectable neuromodulators (Dysport and Xeomin) may be also be used for this.  In experienced hands, the treatment should take no more than thirty seconds. Make certain that you consult with a board certified aesthetic physician with experience and expertise in the advanced uses of Botox. Best of luck

Well-placed Botox to decrease a nostril flare. You'll want someone meticulous. See an expert for a formal evaluation. Best, Dr. Emer
