I have extremely oily skin and was really looking forward to using this product after reading all the promises it made. It claimed to form a barrier between your skin and your make-up so the oil would not come through. My skin was just as oily as ever, if not worse. After about 30 minutes to an hour, without exaggeration, my face looked like someone sprayed it with cooking spray. I've used it several times to give it a shot, but it still did not work. I also bought this product along with three other VERY expensive Jane Iredale products under the pretense that I could return it if I didn't like it. When I got my products and receipt it stated on the back that Jane Iredale is non-refundable, only they didn't mention that on the website I oredered from.
