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

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.

Injecting around the mouth is for advanced injectors because this is what can happen. I'm sorry this has happened. The chin injection hit the DLI on the right so you can't pull it down when smiling. The gummy smile injection prevents the upper lip from lifting. Some people like this injection, many don't. There's nothing to do at this point but wait it out.
