Options for Pityrosporum Folliculitis? Possible to use lose dose Isotretinoin?

Hi I have rosacea, oily skin and mild acne. I've had it under control the past year using a salicylic acid lotion and finacea. I struggled previously with these and was on antibiotics for a year. Now I have tiny little bumps forming all over my forehead. They're incredibly itchy. Along with a itchy scalp. I think it's Pityrosporum Folliculitis. What are the treatment options ? I know this disease has a high relapse rate so I'm worried. Has anyone had success treating this without relapse ?
