yes and no. if it is droopy, i need to see which nerve is affected. for example, if the central cheek buccal area is out on one side, then i have a harder time knocking out the other side because the nerve on the other side is all over the place. if it is in fact that one lip pulls down more due to an injury of a depressor muscle, then i inject the side that pulls down (which is the non paralyzed side) to release that area to balance it with the other side. i tend to use botox to balance faces so that if one area is paralyzed over time the other side creates tension that changes the face. i hope that is clear. may i ask what is the cause of your paralysis? best sml
