My mum (70) has rosacea, the weepy, burning, flaky, spotty kind, plus irritated rosacea eyes and it seems to run in the family as I've had the same on and off since my early 20s (now 40) and one of my sisters is prone to it too. It comes and goes for us, and our triggers are almost always stress.
We have found the only thing to get rid of it is Oxytetracycline antibiotics, which clears up a bad attack really well in a matter of a few days, but I don't want to keep taking these so I'm looking into some alternatives.
I've just found out that a lot of research points to a relationship between too many demodex mites in the skin and rosacea, but I don't think anyone has proved which causes which. Masses on MN about it.
I happened to be with a dermatologist this week for an unrelated issue and I asked her about my rosacea, and she suggested more antibiotics, which I refused. Then she was non-committal about the demodex possibility, simply getting the nurse to give me an 'information' sheet about avoiding common triggers like alcohol, chilli and hot drinks. Personally I think these triggers are more likely to affect the flushing sort of rosacea, rather than the one I have, so I wasn't v impressed.
The flaky patches are just another joyous part of the condition I'm afraid, but sticking to products for sensitive skin (ie no soap) can help lessen irritation.
