I tried the Loreal de-crease a few years ago and didn't care for it much. I remember it creased and I was like, "wtf...hence the name...".
However, I love UDPP!! lol, to each his own I guess! I know everyone gets different results from different products. Its the only one that doesn't dry greasy. I've tried pretty much all of the above mentioned primers and UDPP makes my colors pop and is like eyeshadow/makeup super glue. My eye makeup stays put and color true until I take it off! I also like to use paint pots and shade sticks. But I use UDPP when I need my colors to last a really long time.
