It took me ages, but I finally got around to trying out L'Oreal's De Crease eye primer against Urban Decay's Primer Potion. I had De Crease for a long time before UDPP but I stopped using it because I couldn't get any more product out of the tube, even though you can clearly see that it looks full. However I think that maybe they put some kind of filler between the outside and actual product, but I'm not possitive.
Anyways, I used both primers at the same time and UDPP clearly won. De Crease starting creasing after just 4 hours, and UDPP didn't start creasing until after 7-8 hours. Eight hours still sucks, so usually I put pressed powder over UDPP and it'll last another 3-4 hours for me but I didn't this time.
L'Oreal De-Crease: $8
(the silver thing is a sword if you couldn't tell :)
Right after I put it on, still fresh and pretty.
5 hours later and I've got a little creasing on the De Crease side but the UDPP side is still looking good
at 9 hours DC is looking like a hot mess and UDPP is just starting to crease
