Apple Cider Vinegar (ACV) does seem to work! My method: I use a Q-tip to apply liquid that is 50% ACV and 50% water. The water is just tap. The ACV is just regular brand. I use the Q-tip sparingly-- one tip is used just for the nose, then a fresh tip for the left cheek and a fresh tip (or 2) for the right cheek. I use the ACV application in the morning and in the evening before bed. I sometimes rinse and sometimes just leave it on. I am not clear whether rinsing makes a difference or not. At the same time, I am changing my pillow case every 2 nights. I use one side the first night, flip the case the next night, then on the third night, replace it with a fresh case. Results: The first 3 days, immediate improvement. The next few days, I was back to usual. It is now day 8; I have experimented for a week. I awoke this morning and for the first time in years, my face looked almost perfectly normal in shade and had just one acne bump (break out). Yay!!!
Background: For those who want more detail-- my rosacea has been fairly mild. My nose was always red and often broke out, my left cheek was ruddy with red dots under the surface, the right cheek had it bad with higher red color, many red dots under the surface, bumps and semi-frequent break outs. Before trying ACV, I helped my rosacea by reducing the hormone level of my birth control pills, limiting soap on my face to scent-free either soy soap with goats milk or a yogurt soap, and reducing stress. Still, I had lots of unmitigated redness and outbreaks. Future: I plan to continue with ACV and clean pillow case method. I also plan to replace pillow entirely. I intend to report back with an update on the results of this procedure.
