This primer has a very smooth and silicon-y finish and helps your eye shadows stay on for a fair amount of time. However I wouldn't consider it long wearing and I prefer other primers to this. It also doesn't color correct your eyelids or make your eye shadows appear vibrant.
This is a nice primer for everyday neutral looks (although it wont last 8 hours) but not my favorite primer of all time.
This was the first eye primer that I ever bought, so I didn't really know what to expect. My eyelids tend to crease throughout the day and my eye shadow likes to just disappear on its own, so I was really hoping this would work. It wasn't amazing. I feel like it only made a slight difference in how long my eyeshadow stayed on for. There was still a little bit of creasing (damn oily eyelids!). I'm not sure if I would repurchase this as using a concealer does the same as what this did, but I will definitely keep using this until the tube runs out :-)
