I'm still shocked how well this works! I was actually expecting to be disappointed because every hyped up product I've ever purchased has never worked out for me but this was just bang on. I apply my make-up early in the morning, around 6am, and at 10pm my shadow is still going strong...even my cheapest shadows! Without SI my shadow is MIA by lunch. I will NEVER go without this primer ever again! Also, a little goes a long way so you get lots of product for your money.

This eye shadow primer works exactly as described. My eye shadow would always crease (thanks to my oily skin), but this primer stops all creasing and makes your eye shadow look just-applied all day long.

This has to be the best eye shadow primer I've ever used. It blends so well over my eyelids and doesn't feel dry or greasy after application. Even the most stubborn eye shadows adhere to it like a dream, and it lasts until I take it off (and I've slept with it on). This primer never creases and doesn't fade...it must be witchcraft! It's simply amazing.
