Black Opal Invisible Oil Blocking Gel Primer

This primer in gel form seemed to me ideal for under foundation. But in practice, that is still disappointing... I like the fact that it prevents a fat t-zone, which is ideal for me. Only the problem lies with the texture of this primer: gel. It's quite a disaster... The foundation will flake due to this gel. And I see that clearly in the mirror. That gives a very sloppy look. Like my skin is impure. I don't understand: this is being tested before it hits the market, right?? Then you notice that it doesn't work properly, right? At least for me no more gel texture as a primer...
