This product I first got as a tester and then purchased the full size. Absolutely love the feel of it on the skin. It's a great primer under a BB cream or on it's own for a fresh look. Definitely makes me feel a bit more glowy on a day where my skin looks dull.
I don't use it as an everyday primer as it's a very expensive product, but still love it!
I had never used a primer before and was recommended to use this one. I sometimes use this when I don't want to use a full on moisturiser as it is not as heavy. I really like the way it makes my skin feel and I think that it does make the makeup last longer.
