I have lost count of how many of these I have bought! It’s a staple for me 

An excellent pore-smoothing primer makes the skin excellently prepared for makeup

it makes the foundation shift, but if you use it without, it's fine

This was recommended to me by a make up artist. Been having problems with oily aging skin. I can’t recommend this primer enough it does the job minimizes the look of my pore (one large pore) will definitely be buying again. 

Nice primer, but I find that it does nothing for my pores. They are still visible over my foundation and appear larger too. The packaging sucks too; hate these squeezy tubes especially towards to end!
