I've only had this applied on me a few times (by makeup artists) and each time I feel like I should have used my own foundation. With a silicone primer, I found that it just slid off my face -- in spots. In other places, perhaps where the primer didn't go on evenly, it seemed to grab on, so that it was impossible to blend or touch up nicely. With just a light moisturizer, it initially looks wonderful, but still creases around nose & mouth and under eyes in a way I haven't seen since I stopped using the most terrible drugstore foundations. At least without primer it was possible to blend the creases away -- but I looked best at the very start of the day and at the end when I'd basically wiped off all the foundation. I don't know if it would last better with a different powder, but many layers of the HD setting powder did nothing. The only reason I'm giving this 2 lippies instead of 1 is that the colour match was good and I'm open to the idea that someone with extremely normal, young skin (NO dry patches, NO increasing oilies through the day, not ONE fine line) might be able to use this. Which: why would they bother?
