Dysport on chin, crooked lower lip, and smile. Any suggestions?

It is never permanent but it does seem like forever when you do not like what is going on.  The chin is tricky and when it is not done correctly you look like you had a stroke.  This will eventually wear off.  Do not have treatment in these areas again and do not have service with the doctor who injected you again.  Do not case improvement for this resolving service.  Let this wear off.  If you get out 6 months and things have not fully resolve, which is unlikely, consider reposting here or see a very experienced cosmetic dermatologist or surgeon for input.

Thanks for this important question. Your angle of mouth depressor muscle was also affected. You can wait it out and the effects will go away or you can have the other side depressor injected for better symmetry. Speak with your injector and don't forget the product migrates a little and no one can control that 100%. Warmest regards,Dr. ALDO

It is unfortunate, but I suspect from your description, that the Dysport
was injected or diffused into the depressor labi muscle. In some cases if the
undesired effect is not severe an expert injector familiar with facial anatomy
can inject the opposing side to balance. Since it has been 2 months since the
injection, my suggestion would be to wait it out as the effects should resolve
3-4 months after the injection. Good Luck!
