I have been so busy that I haven't had time to use the MSFs yet, but I did wear Tropica yesterday over Bare Minerals' original primer. I only had a little fallout when applying, but I really did not like the color it came out as thanks to the primer (which is considerably darker than my skintone; ditto for UD's lightest primer shade). I'm going to try it again tomorrow without a primer and see how it looks.
Yeah they don't play well with primers. And they're actually supposed to crease, believe it or not. MAC was on this crease kick for awhile. Crazy trend
What does it say for my weird skin that they have never creased on me?
I can wear those babies for 12 hours and have nary a crease or clump issue. I have no idea why they work so well on me, but I love them. I have almost all of the colors, and they are my go-to easy eye look. I use the 242, sweep one layer on, then pat another layer on top of that. The purple one somewhat fades on me after 5-6 hours, but otherwise, no issues.
