Asked By:diamondeve21 in Walnut, CA

I have med/large bite muscles and received botox on my jawline. I first rcvd 30U of botox on each side of my cheeks. Two wks later, I rcvd 10U on the right and 15U on the left side of my cheeks. On day 4 after my 2nd inj, my smile became CROOKED! When I smile, the right side (rcvd 30+10U) have a weaker smile compared to my left. How often does this happen? Is it caused by inj area, amt of inj or inj technique? Did it hit a nerve or another muscle? When will I recover? What can I do to help it?
