This setting spray is awesome if you have oily skin! I have tried many different sprays, including the ones from Urban Decay. I find that the Cinema Secrets Super Sealer works best for me. My makeup tends to stay on a lot longer - especially if I spray it on before I apply my makeup, as well. It's supposed to work as an antiperspirant when applied prior to makeup - it's not warm enough for me to really say if it works as an antiperspirant in really hot weather - but during the warmer Spring months, it's been great! I highly recommend at least trying out the 2 oz bottle - you can find it for around $10 - if not cheaper - online. I tried out the smaller one and then immediately purchased the 8 oz bottle (around $30). LOVE it!
