This is described everywhere as the holy grail of eyeshadow primers only it doesn't work for me. I think this product is just not suitable for people with greasy eyelids because it creases super fast.
To make a cut crease it is a good product with a lot of pigment only a pity that I paid 16 euros for it because I am now with a big tube.
It does make your eyeshadow beautiful in color.
