Hello, 4 months ago I got Dysport in my frontalis, 11s, corrugators, and brow lift with a new injector. When I raise my brows, I get a bulge in the lower center of my forehead. I got Dysport again 10 days ago with another new injector, same thing is happening. Would a specific touch up help this? My injector seemed to be unsure if it was a frontalis or brow issue. I had not had this issue prior.
