I dont think I have rosacea but I have developed redness in my Tzone lately (Im suspecting because of proactive) and I do think it has calmed the redness down. I didnt know if you were supposed to use the 100% pure aloe vera, which I couldnt even find, or the one you buy for like sunburns that has a couple other ingredients in it. Anyways, I put it on before my regular moisturizer, Cetaphil, because it seems to make my face feel tight. I will keep using it a update if its helping. I did however discover that the green concealer and powders from physicians formula help tremendously with redness. I dont even have to wear normal colored foundation over it.
