Smile is ruined from Botox! What went wrong? (photos)

Botox injections can be used around the mouth to lift the corners of the mouth, decrease chin dimpling and expression, reduce gummy smiles and to halt vertical lip lines.  However, it is best done by an expert injector because injections of too high a dosage or wrong location can lead to negative results such as you are experiencing.  The injections have effected your depressor labii inferioris muscle which lowers and everts the bottom lip.   Thankfully, it will fade more quickly than other areas of the face; however, you could consider treating the opposite side to create symmetry for the time being.  Make sure to seek out an expert in facial injectables if you want this corrected and for all treatments in the future.

Thank you for your question.
In my opinion, the asymmetry you are having is from right lower chin injection. Based on your picture, you have weakness of the muscle of the right lower lip called depressor labii inferioris. Its function is to lower the lip. When inhibited by Botox, the lip on the affected side won't move down with smiling which results in asymmetric smile. It usually takes around 3 months for your symptoms to improve.
I hope this helps. Best wishes.

It appears that your asymmetric smile may be due to having Botox placed in the depressor anguli oris, or possibly the depressor labii inferioris, muscle on one side but not the other.This muscle pulls down on the lower lip. By temporarily paralyzing this muscle with Botox, the lower lip on the affected side will no longer move down.If you wish to improve your smile to a  more symmetric one, you may have Botox placed on the non-affected side's depressor anguli oris/depressor labii inferioris.The other option of course is to wait until the Botox wears off over the next 2-3 months. Thanks for sharing.
