I needed a primer because of my dry skin, and I heard that the product itself is great to use to get rid of flakiness. I purchased the purple coloured one, to get rid of yellow tone (as I am asian, and sometimes it becomes so apparent, I look like a Simpson's character!).
I found that the primer did not work in any way that I wanted it to.
In fact, upon applying this under my foundation, my skin appeared grey, and I looked quite sickly. Possibly it is because I bought the wrong kind of primer colour, and should look towards a more neutral one.
However, I also found that not only did it not moisturize my skin, but there was no different feeling after applying the product. I didn't feel any smoothness that I usually do when using other primers.

The scent of the primer was quite nice however, it smelled fresh like cucumbers!
It didn't break out my skin, which I'm usually afraid of, as my face is very sensitive to any kind of makeup, whether oil based or not.

In the future, I will not be purchasing this primer again, and would urge you to consider and realize what kind of skin "problem" you have, and to be aware of its capabilities.
