Despite coming in a fairly small tube, it's lasted me quite a while! I don't need to use a lot to get the perfect prime coat before putting on my makeup. It definitely does what it says, it won't clog your pores and it's so nice to finally not breakout all over my face after putting on my makeup. My skin is so sensitive to new products and can be overly oily, so it's always hard trying a new product that promises a "photo-finish" but this one really does the trick. I used it before my best friend's wedding in which I was a bridesmaid and my makeup looked perfect all day long into the reception. Once I've used up all of my primer, I'll definitely be ordering more.
