I purchased the Catrice Prime and Fine Anti-Red Base because I struggle with terrible red pigmentation in my skin, especially in my T-zone.
I'm sad to say this product is basically unusable to me, purely due to the fact that it contains an insane amount of glitter! It basically made my face look like a disco ball! It is a pity, because the product is reasonably priced and has quite a nice texture to it - applies easily and is non-greasy. It did also help to refine my pores, and I found it helped slightly in covering up the redness, but definitely not as much as I would have liked.
All in all, I would give this primer another try if the amount of glitter in it was corrected.
