I have squinty eye when I smile, why? (photos)

Everyone has slight asymmetries in their body and potentially the orbicularis muscle is stronger on one side.  I wouldn't do anything surgical.  If this bothers you, consider Botox or Dysport with an Oculoplastic Surgeon.  

As per the other respondents I agreed that Botox or Dysport would be the way to correct this.  It is likely due to a tightness of the muscle could be inherited.  A small amount of Botox would correct this for a few months.  I would be glad to see you in my Altamonte Springs office if you would like a free consult.

It sounds like you could use some botox or Dysport to relax your orbicularis muscle.  That is the muscle that is responsible for the contraction you are describing.  Botox and Dysport are neuromodulators or muscle relaxers.  I think this would do the trick for you.  Just please make sure you see a plastic or oculoplastic surgeon who knows how to best correct this.  Good luck.

Do you mean when you smile they have a squinty look?  If crow's feet bother you, then botox can help with that.  Best of luck.

Posted photos appears as a very very slight asymmetry. I would do nothing.............................

The muscle that lets you tightly close your eye is called orbicularis oculi. It goes all the way around the eye. The lateral part is responsible for crow's feet, the lines that form at the corner of the eyes over time due to repeated contracture of this muscle. Part of a really authentic smile includes activation of this muscle, and it sounds like yours is overactive.The answer therefore is Botox, a safe and effective therapy that temporarily relaxes muscles for 3-5 months. This may be something you wish to start now because an overactive orbicularis muscle will eventually permanently etch crow's feet lines into your skin around the lateral eye and upper cheek. Find yourself a reputable injector and get their qualified opinion.Best wishes!  Harry V. Wright MD, Sarasota, Florida

You have some over activity of your eye muscles causing asymmetry.  Everyone has asymmetries in varying degrees.  I would consider a neuromusculoparalytic agent such as Dysport to soften this problem.
