Hi, cooks, last week I was diagnosed with rosacea, too - after delaying a visit to the dermatologist for about 3 months. I'm just getting used to my lovely new complexion and its special needs.
From what I've learned so far, rosacea is an inflammation disorder, and triggers that worsen the condition vary from person to person. It can be helped but not cured. And it can take time to figure out your triggers, be they dietary, environmental or "other". So far I've identtified sun, heat (indoor and outdoor), anxiety, ketchup, PMS and red wine.
I've gotten a lot of great info and advice from the following discussion board:
