Minocycline
"I am over 40 with adult acne for years. I had it under control with epidue for years but something hormonal happened and I had a severe break out and it was bad. My dermatologist started me solodyn 105mg. It worked immediately. My acne cleared up and my face was smooth again. But my only side affect is I have gotten really dark, I haven't read anyone complaints about getting dark so I would  like some responses to my post. I don't know if its because I am a black woman.  But after reading some of the posts I will start taking a lesser dose to see if that helps."
