Unfortunately , you are stuck with the effect for approximately 3 months. I don’t recommend adding more Botox to even things out. Follow up with your injector.
It is difficult to judge due to the fact that there are no before Botox pictures. Everyone responds differently and a lot is based upon your baseline and the amount needed to achieve your goals. I recommend that you have a conversation with your injector
Masseter and downturned mouth can be treated with Botox during the same session. I think you will be happy with the results.
After looking at your picture, I believe you would most likely get a better result with fillers. See your facial aesthetician for a personal evaluation.
Based upon what I see in your picture, Botox can definitely improve the wrinkles. See a qualified injector for a face to face evaluation. Good luck.
