Are Botox injections near nostril the only way to treat gummy smile or can injections across top lip help as well? (Photo)

To correct a gummy smile the injections are done near the nostrils. The injections across the upper lip are sometimes used to address "smoker's lines". Results from Botox are temporary and you should return to your previous look gradually over the next few months.

Precise placement of botox around the mouth is the best treatment for gummy smile.  I suggest you see an expert for a consultation.  Best, Dr. Emer.

Thank you for your question.  Botox injection that helps with the gummy smile is an injection just lateral to your nostril.  An injection across the top of the lip will not drop the upper lip but it will affect the orbicularis oris muscle.  An injection in this muscle will weaken your ability to purse your lips (affect drinking out of a straw).  Make sure you go to a Board certified plastic surgeon for your injections.  Best Wishes
