I had a terrible reaction from expressions. Missed 10 days of work. There must of been a contaminated protein. I had it done by a plastic surgeon. My face swelled up and I had to have 2 drains put in. I also had2 b put on prednisone to reduce the swelling. It was the scariest time in my life. It was my 60th b/day present 2 myself. Never again!
