I can't exactly figure out what L'Oreal Revitalift Miracle Blur is. On the reverse of this sample, sent to me my my lovely reader Lanalei, the manufacturer defines this cream in terms of what it is not while hardly giving any information what it is.
This is a very thick cream which immediately brought Smashbox Photo Finish Targeted Pore and Line Primer to my mind. You are supposed to use this over your moisturiser to visibly smooth your skin. You may leave it like that or follow with a foundation of your choice.
I used this cream on my nose and cheeks, where my pores are most prominent and I must say that this cream successfully prevented my fundation from getting in the pores much better than most primers. How does this work? Well, it feels pretty much like any silicone primer, but it's way thicker, so it settles in your pores and fills them in, making them imperceptible under foundation. If you don't mind silicone-based primers, this might turn out to be a really effective tool for disguising large pores. I must say this works for me. I apply it on my nose, where my pores are volcano-size and my foundation always finds a way to flood these craters while leaving bold patches on remaining parts of my nose. The result is that my foundation stays in place and doesn't migrate towards the pores during the day. I haven't experienced any break outs or deterioration in my skin condition.
A little goes a loooong way. You need only a tiny drop to cover those target areas.
I wish this thing had also some mattifying properties. I suppose it does control oil a bit, but a mattifier it definitely is not.
I think that if large pores are your issue and you don't mind actually clogging your pores, this kind of targeted pore primer might be exactly what you're looking for.
