My son has used dandruff (Selsum Blue) shampoo for prednisone induced acne with pretty good results. We haven't tried it yet, but I have heard using Milk of Magnesia as a wash or a mask helps too. It is a laxative so ONLY use it topically!!
I think Accutane has been pulled off the market recently for it's link to UC - so stay away from it if it is still on the market.
