I really love this product. I use it everyday on myself and also on most of my clients in my line of work. I use water based airbrush foundations (such as Luminess Air and Dinair) and as this is a water based primer its works amazingly well together. It has a matte finish and is slightly tinted to blur imperfections and give a smooth base. It's a dream for oily skins and keeps oil at bay and in my experience it doesn't sit in pores. I usually find silicone primers sit in my pores after awhile which is why i intially looked at water based primers. It also keeps airbrush make up looking flawless for longer.
As its water based it doesn't bring you out in spots and doesn't clog your pores. It feels light and non greasy and is a great little product.
