Botox for asymmetric smile? (Photo)

Thanks for this great question. Since this was a childhood surgery, it is unlikely that the nerve will come back. You have a nerve palsy (marginal mandibular nerve) that prevents the right corner of the mouth from being pulled down when you smile. The best treatment would likely be to relax the opposite side to ring the left corner up. The most famous asymmetrical mouth is, of course, Sylvester Stallone who was born with the same nerve defect that causes his bottom lip to look higher when he smiles/grimaces. I suggest you speak with an experienced injector and consider a combination of dermal filler and neuromodulator. You can also try Dysport or Botox without the filler to relax the muscle which pulls the mouth corner down. Best wishes always, Dr. ALDO :)

Fillers and botox can be used to improve this area. Lasers or surgery can sometimes help asymmetry.  See an expert. Best, Dr. Emer

Thank you for sharing your question and photographs.  In order to balance out your smile you would need to have Botox placed in the areas of the left lower chin where the muscles responsible for pulling the lower lip downward exist.  This typically involves treatment of the depressor anguli oris and depressor labii inferioris.  Hope this helps.
