I tested this SKII Foundation today. It is the best foundation ever! If you have a chance to try this, you must! Worth every cent! It comes with an instructional CD also. You can actually put it on over anything that is not liquid based. Apparently, it is attracted to water. So you can put on any concealer or coverup any red spots, put on eyeshadow, powderblush, etc. The wet stuff, like mascara goes on afterwards. However, she did say that you can put it on after everything else if you let everything else dry. After you spray it on, it takes a couple minutes to dry, and then looks beautiful. Flawless (well, as flawlessas possible!)!!! It's supposed to last about 3 months. I don't know how because seriously the packet is like a sample size of lotion! Definitely try this if you are looking for a beautful finish on you face! Anyone else like it (or dislike it)????
