Uneven smile after treating masseters with Dysport.

Some of the Dysport has perhaps migrated to affect surrounding muscles and affect the balance of the muscles during your smiling attempts. Fortunately, the effects are reversible, but it may take up to 3 months.

I'm sorry that you are experiencing an uneven smile after Dysport treatment. It may be related to the product being injected in the wrong area or the product migrating after injection. Fortunately the effect is temporary and your smile should return to normal as the product is metabolized.

Thank you for your question. It is possible that the Dysport has migrated from the masseter muscle to an adjacent muscle resulting in a temporary change in your smile. Your smile will return to normal once the Dysport wears off in 3-6 months. However, I do advise letting your injector aware of this so this can be avoided in the future. Best of Luck!

Thank you for posting your question. While the Dysport injection targeted the masseter muscles, it is possible that the toxin migrated to adjacent muscles involved in smiling, resulting in a temporary change in your smile. The effects of a neuromodulator typically last 3 to 4 months, and therefore your smile should return to baseline in a few months. 

Sorry to hear about your experience. It is possible that Dysport diffused to the adjacent muscles and did not stay confined to the masseter muscles resulting in a smile abnormality. Your smile will return to normal once the Dysport has worn off.
