It was Retin-A, she had a very serious allergic reaction, on top of that you can't go into the sunlight much while using it, as one poster has said you will get some serious skin issues. It worked well for my wife until she almost died from it!
Retin-A was the one that scared me badly. See my post # 128. Very bad stuff!
Sorry... that’s *scarred* me badly. (Stupid spelling grumble snit)
