This is the first primer that I have used. I'm not very clued up on colour correcting but I do find this primer to even out my skintone. The oil free formula works well on my T-zone. If there are areas of my skin that I drier I prefer to skip using this primer on those areas as I found that it accentuates the dryness.
Overall since my T-zone is a problem area for makeup longevity, this primer does work for me. I find that I have to apply face powder less frequently when using this product as opposed to not using it.
I also get a smoother application of my foundation and since this primer evens out my skintone I get better coverage regardless of the fact that I use light to medium coverage foundations.
