Benefit's Porefessional is designed to be used as a primer to smooth out skin and minimize the appearance of pores - which it does excellently.
This oil-free, silicone-based product feels velvety to the touch, and applies with ease, leaving a matte finish. You can apply this pre or post foundation depending on your needs.
It creates a smooth canvas for foundation to stick too, but can also be applied on top of make-up in targeted areas to smooth out the skin.
I find this particularly good for smoothing out pores on my nose and chin, giving a soft finish to the skin.
If you like your primers to be brightening, then something like That Gal or Girl Meets Pearl might be more up your street, but for those who want to smooth out skin and give a matte look - Porefessional will be right up your street.
