Can Dysport in crows feet effect cheeks?

Sorry to hear about your Dysport experience.  You may have had part of your smile muscles affected.  This would be something that should wear off in a few months.  I would make sure that if you were to try this again that the you visit with a well trained and experienced injector who understands the anatomy of the crows feet/smile muscle region.

If Dysport is administered in such a way that it affects the muscles which elevate the cheeks this will have an effect on  your smile.  If this has happened to you, the good news is that the effects of all of the neuromodulators on the market today are relatively short lived.  Best of luck.

If Dysport was injected into the zymaticus muscle below the
cheekbone, it could cause this problem. Please schedule a followup visit with the provider that performed the injection.

If the Dysport is not properly placed, it can affect the zygomaticus muscles.  These are the lifters of the upper lip and your smile will be abnormal.  Under eye placement of Dysport should be left to the experts. 

Yes, if neurmodulators are not expertly placed under the eyes it can absolutely affect the upper cheek muscles and cause wrinkling and even droopiness. It will wear off in time, but could take 3-4 months to fully resolve. In the future either don't treat this area at all, or seek a more experienced injector for correct placement. "This
