Anything that claims it will 'blur' my skin immediately grabs my attention. (Although can we take a moment to giggle to ourselves about those apps that blur your skin so you end up looking like a fuzzy cloud? Ok thanks). I think L'Oréal Nude Magique Blur Cream is a better version of Miracle Blur, which I was never too impressed with.
I have this in the shade 'Light to Medium' + although it does come out of the tube in a shade, the pigment doesn't really transfer onto the skin. My one problem with this problem is the packaging, because it tends to squirt out + go all over the place + it is difficult to get the desired amount of product out. However, I do think it does a great job of evening out my skintone + creating a great base for makeup because it makes my skin super smooth. I wouldn't wear this by itself because it doesn't provide any coverage but I do like it as a primer. It does feel quite silconey so it gives a velvety finish which I think would be fine for oily or dry skin (my skin is generally quite normal).
I definitely think this would be a particularly nice primer if you have slightly blemished skin or visible pores because it does make everything look a lot more even + smooth.
