Texture: A creamy gel, if that's possible to imagine. Not sticky, but it did not glide on as easily and evenly as I had expected.
Color: Goes on translucent, but made my face shiny for quite some time which I wondered about.
Smell: Not much, it's faint but not disturbing.
I was disappointed with the packaging of this sample, it cannot be easily closed to keep it from drying. It comes in a pouch that is very full (good) but if you try to fold it over to close it, more and more just spills out (bad!!).
So my results may have been affected by this primer drying out a little.
The initial try: I did not see a major difference in the side I had applied this on with BE, and the side I just used no primer on. It flaked a little and I think it may just buff right off.
The two other tries after: Flaky, smudgy mess! I don't remember having a foundation go on this badly. Especially after buffing the MMu in, it looked like my skin was peeling. I tried mixing the MMu with this primer to no avail. Looked like a bad sunburn.
Overall effectiveness: I did not see enough potential to try it again or buy it full size. I'm disappointed because I like their other products. I keep trying this primer over and over, I don't get acceptable results even with the leftovers that are not so dried out.
