I'm guessing rosacea is a type of bacteria.
Not much I can tell you. Acne is a side effect of steroid use. If you already have acne, it almost always gets worse during a cycle.
Definately something you want to get under control before your next cycle. Also have a plan to abort the cycle early if it starts getting too bad. No use being big and freaky if your afraid to take off your shirt.
