I wasn't impressed with it either. I didn't get an irritation, but the coverage was heavier than BM and it got cakey after a few hours.
But I did find a very cool website:
http://cosmeticscop.com
She sells her own brand of skincare and makeup, but surf around the LEARN sections. She has zillions of tips to get the most out of just about any beauty situation you may have.
For example, I have large pores on my nose and cheeks and had been using a product with benzoil peroxide to keep the clogs at bay - without noticeable success or improvement. Paula says that BP is an anti-bacterial and doesn't penetrate enough to improve pores and keep them clear, and says you should use a product with 2% salicylic acid instead.
Well, lo and behold - it worked! Pores are noticeably smaller and clogs are not a problem anymore.
