Can Dysport in chin cause a lopsided smile? (Photo)

Dysport and Botox injections can certainly result in smile asymmetry, and as such, require extreme care when being injected in the lower face.  Luckily, the results are temporary, and should resolve over the next several weeks.  Best wishes.

Yes, it can affect the lower lip and the corners of the mouth if the product migrates too much. It does not affect the upper lip and middle of the face if only the chin is injected. Best wishes, Dr. ALDO :)

If dosed inappropriately or not injected correctly, Dysport can cause a lopsided smile. Please see a highly experienced certified injector to complete all your injections. 

Thank you for the question and pictures.   Dysport (or any neurotoxin) injected into the chin can cause an asymmetric smile.  This is from the neurotoxin usually migrating to the muscle that pulls your lower lip down (the depressor angularis oris, or DAO).  This effect should wear off before the usual 3-6 month time period because there is presumably less neurotoxin there than in the intended muscle.  Good luck! 

Thank you for your photos. It is
possible that Dysport injected in your chin can cause a lopsided smile. Always
make sure you seek treatment from a board-certified dermatologist.
