Olay hydration flawless blur

Now this a product I was so confused by as its called flawless blur hydration, I thought it must be a primer but it was a moisturiser that's a thick consistency. I find primers on my skin make no difference what so ever so I've been layer this and then the Loreal matte infallible primer which together they keep my make up on all day.
This product is really moisturising and has spf 15 in it.
Fairly sure this product is £8.99
