As I am such a happy new AE customer that I bought 6 palettes in a short time, I only got around to wear Sahara once so far, trying only the (cool) bottom row and the 2 lighter shimmers. However, this occasion turned into an unexpected (and unusual) long wear marathon test, and wow, did this palette stand up to it...! Without any fixing at all, over 40 hrs later the mattes were still exactly where I had put them (on top of AE primer) - I could hardly believe it. The shimmers had wandered a bit, as I had only put a dry dab on, but I had no fallout on my cheeks. I found the formula and pigmentation very user friendly, the colours beautiful, and can't recommend this palette (and all the others!) enough.
