I get to read and learn from clients their issues related to rosacea.  Most research concentrates on genetics, diet, stress, extreme temperatures, bacterial/parasitic infection, etc etc etc.  However, just recently, a client told me that she ONLY experiences rosacea breakouts when she is PMSing.  Other than that, she has no problems.  Because I haven't seen any indication of her rosacea, I asked her to send me pics of her skin when she does have a rosacea breakout and she sent me good close ups of her skin.  Indeed, it is rosacea! It is not acne, and she gets them on her cheeks.

I googled this particular situation and found some information.  However, I would like to know if anyone has any experience with this and how you deal with it.
