This is going to sound preposterous, but I promise it is true! I have suffered from roseacea for about six years. Sometimes it was pretty bad. Tried everything. Then, I travelled to Turkey and Greece for one month this summer. I knew sun was a trigger for my condition but there was not much I could do about it, since our days were long, in the sun, sightseeing the ancient world. Sunblock simply fell off, it was so hot.

My face did become beet red. I was so embarrassed. it stayed very red most of the month.

When I returned, however, my entire facial skin tone evened out. My skin looks much, much better than before I went on the trip. And I wondered -- yes, the ultra violet rays are dangerous, but what  about the other types of light in bright, direct sunlight? Can they possibly be related to the lights that are used to *treat* rosacea? For the same number of years I have had the condition, I have been either in school, studying constantly, or teaching and grading papers. Seldom going out in the sun. Maybe I was lacking some of the types of light that *are* good for the skin, as well as those that are bad?  Because for one month I got the whole spectrum.  And, while I still have my condition, it is nowhere near as noticeable and I have a healthy, less ruddy glow.

I'm not recommending anyone do what I did, but I find it very interesting that I did what I am not supposed to do, and obtained spectacular, though unintentional and unexpected , results.  I would love to know how and why this is the case.
