I'm pretty dry and after wearing this today I am an oily mess. Completely took me by surprise since I am a long time LM primer (original formula) user and don't get slick using that. Disappointed since I really, really wanted the added benefit of the SPF.
I happen to love this primer with protection and think it works well under my Laura Mercier tinted moisturizer which is my summertime foundation. I love that it has spf and primer abilities in one so willing to pay the price. It is probably not for oilier skin types as noted by the reviewers below but I have normal to maybe combination skin in the summer so it is working for me. My chin gets a smidge oily and I just blot that. My makeup still looks fresh at the end of the day.
I didn´t notice any difference in makeup-longevity or better application after using this primer, except that my skin turned very oily after a few hours and after two days of using this, my forehead was full of blemishes. Won´t use it again, obviously.
I agree that this primer is comfortable to wear. I also like the broad spectrum SPF 30. However, after applying the primer over my oil free moisturizer, my face was a shiny mess. I ended up using twice as much powder as I normally do to combat the oily shine. Every time I looked in the mirror, I had to blot my forehead and nose. By the end of the day, my face felt like a mask from all the powder and I couldn't wait to get home to wash everything off. So unless you have super dry skin, I don't recommend this product. Yuk.
I've worn Laura Mercier for years. However, I had never tried their new prime protect until a month ago. I have combination dehydrated skin prone to acne. This primer works really well at maintaining my moisture, keeping my makeup on and it does NOT break me out!
If you don't want to spend the money on deprecate products and love a natural look and a nothing feel, this primer is for you!
