M1Kendra it is possible that you are on too much Pred, most with locah only take about 3 mg, 2mg in the very early am and 1 mg in the early evening/late afternoon. Those with classic cah take 5mg sometimes less than that from what I have read.
To be honest the hair on your face may thin, and new hair may not grow but the old hair will always be there. I strongly suggest you looking into laser hair removal. Since you are being treated it should take very well. Laser hair removal is a Godsend!
It is also possible that the higher than necessary dose of preg can cause your acne. Please see another endo soon.
Do you have copies of your labwork?
