When I went to buy a concealer, I received a sample as a candidate for my next foundation. I've been using YSL's All Hours (LN4) for a while now, more for the color than the finish, but this NC12 has a slight reddish hue to it than LN4, which makes my complexion look healthier. Overall, this series seems to have a strong yellow tint. After half a day of application, this product is not extremely shiny, does not get into pores, does not disappear, and does not come off even when I touch it with a tissue! I can feel that it sits properly on my skin until I remove it. When I run out of the YSL I have, I will purchase this one.
