★★★★☆
I found the topical borax/hydrogen peroxide treatment, followed by spot application of tea tree oil to be helpful in controlling my rosacea. It didn't eliminate the redness, but has reduced the red bumps on my cheeks dramatically.
Eliminating alcohol and diet soda/ artificial sweeteners other than stevia also helped a lot. If I cheat and have a diet coke I notice many more bumps the next day. I'm not sure if it is the artificial sweetener or something else in the soda, but it is a reliable trigger for me.
