I have quite an oily nose and recently my pores have been quite visible leading to my nose seeming even oilier and the shine appearing much quicker when I am wearing makeup up.
First off, this is not a pore shrinking solution, it is a temporary pore concealer, it will not shrink your pores.
When I apply this product, I use my regular primer everywhere else, but leave my nose and the surrounding couple of cms free. I use my fingers to apply this product as I do not own a stiff enough brush to really work the product in with.
After application I leave it to sit for a minute or so before applying my foundation. I do see a difference immediately when I use the Instant Perfector, my foundation applies and sits nice on my nose, and it definitely takes a lot longer for an oily shine to appear.
I would say that it does not last the full eight hours on myself, but it does give me an additional 3/4 hours of non shininess.
I do not think that I will repurchase this product as I would like to find/try out some other similar products.
This is a skincare product, not a makeup product. If you are wanting a makeup product buy the Porefessional. When I put this over my enlarged pores, it is very creamy and sits beautifully on the skin. For me, this is a temporary fix rather than a long term skin care solution. It also won't last for longer than 4 hours.
