Ladies I just have to report this here: that Marc Jacobs Genius Gel foundation in Cocoa Medium, set with the Perfecting Powder foundation in Cocoa, has made it thru 13 hours so far. I did my face (I did set with a heavy-duty setting spray), but I am very oily, and it has held on my face through a looong day, part of which included a funeral and graveside service. I have blotted once, and powdered once. That's all. I usually do that much by 10 am. This is the second time it has performed well. The first time I had it put on at a Sephora with no primer, and it lasted maybe 8 hours before noticeable breakdown, but this time I used Boots No. 7 Beautifully Matte primer. Feels like nothing on, a little goes a long way, very pigmented. It went on with medium coverage and still looks decent. This stuff is NICE. I didn't want to like this stuff, but I do. This is my official "special occasion" foundation lol.
