I decided to try this as I'd used Urban Decay primer potion for a while prior and wanted something I thought might enhance my eyeshadow colours a little more. After reading several reviews about how great this one appeared to be, I thought it was a no-brainer. I also have a Too Faced eyeshadow palette which I adore and the colours are fantastic, no irritation or anything. Unfortunately though, this wasn't as good as I'd hoped. I applied it to both eyelids and instantly realised it was incredibly thin. This worried me a little because I wanted something a little thicker to make my eyeshadow pop, but I stuck with it... Until my eyelids started to feel like they were on fire. Within two minutes of applying, I had to remove the primer completely. I tried again a few more times in the following days, but it only became more irritating on my skin and left my eyes sore and itchy. I won't be trying this product again (but I'll always be back for more eyeshadow!) This is just a warning for anyone with sensitive skin and/or eyes!
