I started taking this after reading this on another thread. I was at my wits end because my Rosacea flared up for no apparent reason. I use Metrogel 1% everyday as well as get laser treatments once a month, so I just was looking for anything to help. I come across this forum and thought what the heck...IT HAS HELPED ME TREMENDOUSLY!! I take the 3000mg L-lysine; 1000mg Vitamin C & 25 mg of Zinc twice a day. Literally within a couple of days my face was back to normal. I also do not seem to flush as bad under stressed situations. Thank you so much to whoever posted this, I am forever grateful!!
