I did notice a difference between using this eye primer and not using it! It does make your eye makeup last longer and the color turnout is better! However it didn't seem to make it last that much longer, it probably only extended the eye makeup by an extra 2-3 hours, but maybe it's because eye makeup just generally fades faster on my lids compared to other people. I would give this a try though!
