I had filler injection in june and not long after my face started to experience burning sensation all over. My eyes drooped, one side of my face is bigger than the other, i have swelling on my forehead and my top lip caved. I went back and the lady who performed the treatment and she started to use Focus RF to reduce the swelling on one side. Although, it worked and reduced the cheek i now have problems with both cheeks drooping when i lean to one side. Now they refuse to treat me!
