Having the most oily eyelids in the cosmoverse, I'd regularly seen this touted in s&b but dismissed it because NOTHING stops eyeshadow (even long wear, waterproof, bombproof, tattoo-like formulae) from sliding off my eyelids.
Then I was passing through house of Fraser on Friday and saw their new counter, complete with missing sales attendant, so I wandered over and had a look.
Reader, I bought some.
It's the best thing I ever did. It is amazing! So much so that my eyeshadow is more or less still there in the morning. Not that I am slovenly of course, this is merely for test purposes. But I just wanted to say...buy it! It's fantastic! And thanks to those touts who've sung its praises here before. I owe you!
