Catrice had so many versions of primers over the years and this is just the latest. They describe it as a mousse, but it's more of a mix between a mousse and a cream. It promises to hide pores and skin imperfections, as well as it claims it can replace a foundation depending on the desired coverage. 

Texture and effect: The mousse-cream formula feels less silicone-velvety than primers I'm used to. Due to that it's also the least drying such primer I've tried, yet it leaves a matte finish. It hides/fills up more prominent looking pores and creates an even surface. It can't handle lines though and can make them so much worse in combination with more moisturising foundations. Foundation applies with no problems over it.

Shade: Catrice calls this an universal shade, but this is very dark for someone pale as me and I think anyone bellow light-medium skin tone won't be able to wear this alone. I need to be careful not to use a lot, blend it well and put some coverage over it, but it still ends up patchy looking on me, so I'm having trouble wearing this.  
Staying power effect: This lasts nice on my skin and unlike a lot of similar products it doesn't go all dry and cakey with time, but it also depends a lot on the foundation over it. I found that at more moisturising formulas it emphasises lines a lot time in time like I mentioned above and ends up so ageing. I would only stick to areas that need mattifying and hiding pores. It wears off nicely and evenly.
