I know we all enjoy a bargain and a cheaper alternative! Rimmel WMU concealer dotted on eyelids, smoothed on then left for a minute or so to dry - works just as well as Urban Decay for me. I'm wearing three layers of sparkly eyeshadow today so have plenty of product on and it looks just the same as it did at 7am. It works fairly well as a concealer too although I prefer Bourjois Happy Light for undereye darkness
There you go, two tips in one!
