I started using Oxygen Elements Max a few days ago, having been a previous user of Oxygen Elements Plus (its predecessor). I have found the new version to be noticeable more effective than the older product on my skin. I usually mix a few drops in a little water and put it directly on skin eruptions as it is not meant to go on the skin undiluted. Although the old product worked, the new one clears up the skin much more effectively.
I have also noticed an improvement in my digestion and peristalsis (I have been less constipated).
