Left eye: No base. Right eye: Urban Decay Primer Potion
Aside from the shadow on one side of my face, the side with the UDPP as a base clearly experienced less creasing and fading. Both eyes tended to fade throughout the day, but without a base, why even bother if it's going to look like that?
You may be wondering how long I wore this look. I applied my makeup (albeit rather hastily) at 9am. I took this photo at 7:15pm, after a long day at school, walking strenuously for about 1/2 mile, and running multiple errands, including shopping, all while feeling mildly stuffy from our temperate fall weather! So I wasn't just laying around today, but even still, I usually expect my eyeshadow to stay on a little longer.
I have good intentions to try MAC paints & paint pots tomorrow to see if they're any better! But now you know, a base is a good idea! :)
