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 ispossible that Dysport injected in your chin can cause a lopsided smile. Alwaysmake sure you seek treatment from a board-certified dermatologist.
