Rosacea is supposed to be an infection and they treat it either with NOritate or tetracycline or sometimes other products--which might cause the itching, burning, and peeling.
It sounds a little like sunburn. I do get hard patches with my rash, but it is normally in my darker pigmented areas of my face--the porphyria looking places (plaquenil can cause porphyria). They peel a little but do not itch or burn, mostly are a hard spot of skin. They eventually go away by avoiding the sun.
I have been using medication for roseacea for well over ayear now and it does nothing for my constant malar rash. I have told the dermatologist, but really need to drive the point home. He may try switching my roseacea treatment. He does feel that there is some roseacea around my nose and I tend to agree there, but just in a small area. I don't know if there is a biopsy available for the malar rash.
My rheumie always thinks its the sun but then acknowledges it isn't. He just knows I do get more sun that I can handle, causing the dark patches and my arms get red, not burnt, but as if the skin is inflamed and it goes away fast, sometimes right away when I get out of the sun. I get red in just a few seconds.
Is your roseacea being treated? You might try it if not. That is an easy way to tell what is what. Maybe you are burning really easily like me, which is severe sun sensitivity. There are other skin conditions that can cause similar problems, even allergies to makeup or creams. I would go to the derm and see how much of a scar you get from a biopsy, or about treatments for biopsy.
There are also things lke psoriasis and eczema. We get a lot of problems.
I feel for you I have extensive disfiguring skin problems. You might avoid makeups and creams and the sun altogether, even through windows. When porphyria gets bad, it can make you feel really sick. I keep all my blinds shut all the tim and limit otside time to a few minutes.
Hope you figure it out. LIke me, its probably a combination of many things.
