I can't praise this OxyLift enough, before I used to get bad cold sores all the time especially when I was going somewhere special. Also increases ones immune system highly. I mix with people with colds and very rarely catch them. Honestly give this product a try its marvellous just one thing though, it takes a few months to kick into your system. Then your protected I couldn't live without my Oxylift I take 1 drops in a small amount of water after breakfast everyday without fail. Good Luck and enjoy good health.
