I have never used a green tinted concealer before to hide the ruddiness of my pale skin and wanted to try this to see if it would reduce the blotchiness.  I recommend using a makeup primer under it as the green tinge is very very visible and you should go over it  multiple times to smooth it into your skin. Then be sure to apply a liquid foundation or powder of medium to full coverage to hide the green.  If you don't then you will look like a pale version of The Joker.  I think it does an adequate job but I didn't like the fact that I had to take extra time to blend it and then make sure the concealer was hidden under my foundation. I will go back to my old concealer that isn't as labor intensive.
