What are the complications of gummy smile Botox? Is it recommended in slight cases?

A gummy smile Botox injection complication can be one of 2 things 1) you feel no result 2) you feel as though your lip has lost the ability to move or is elongated. Most injectors administer Botox conservatively in this area to avoid the second option listed above. All the best.  

Neuromodulators like Botox are a great option for a gummy smile. There are 2 main risks really: under correction leaving you unsatisfied with the result and over correction making your upper lip feel dropped and motionless. Finding that sweet spot is a matter of experience, but can give a beautiful result even in mild cases. Find a dermatologist, oculoplastic surgeon, facial plastic surgeon or plastic surgeon who is board certified in one of those 'core four' cosmetic specialties and you will be in the hands of someone who knows the proper anatomy for injections and amounts to inject.
