Slight Asymmetry After the Botox – Dysport Injection?

I would agree that you should wait some more time before evaluating your final result from the Dysport treatment to your crow's feet 2 days ago.  If you still notice some asymmetry after a week or so, I would contact your treating physician.  Often, there are slight touch ups that can be done to give improvement.  

Dysport will start to take effect in a day or two, but may take up to 7-10 days for full effect.  Muscles on one side of the face may respond at a different rate from the other side, so as the Dysport takes full effect you may notice improved symmetry.  Follow up with your physician in 2 weeks, as it's usually possible to perform a "touch-up" at this time if you still feel there is asymmetry.  

It may take 7-10 days to see the full effects of Dysport or Botox.  If after this time you still notice some asymmetry, I would recommend that you follow-up with your provider.  

In general, it can take up to a week for the Botox/Dysport to take effect. You
may be experiencing some swelling from the injection itself which will lead to
the chubby appearance in your cheek. In general, the side effects of
Botox/Dysport are as follow:

1) Light bruising
2) Swelling
3) Redness

As of now, there is not much you can do to calm the swelling down. This is
something that will resolve over the next 1-2 weeks. I would recommend giving
it some time and then reevaluating. I hope this helps, and best of luck.

As others have said, it takes 7-10 days to see the full effect of Botox and Dysport.  Asymmetries at this time may also be due to some asymmetric swelling after the injections.  If you still feel that there are asymmetries after two weeks, revisit your injector.  there may be some touch-ups that they can do.
