Hi and thank you for posting your question and picture! No face is 100% symmetrical and this is just part of our natural individual beauty. However, if this issue is bothering you, it can be best corrected with a combination of Botox and filler injections. Please keep in mind that issues that show themselves during facial muscle movement (e.g. when you smile), can be caused by muscles that are not necessarily located at the affected area, and muscles that are located further can also play a role. Therefore if you decided to try Botox, please make sure to work with a highly experienced physician with great expertise in facial muscles, their anatomy and their mechanics. I hope it helps and good luck!
