An eye shadow base – commonly referred to as an eye primer – is an often overlooked step to eye shadow application, but applying a primer takes almost no time and delivers big benefits. Primers make your eye shadow color last longer, intensify the shade and even out your natural coloring. While an eye shadow base is not completely necessary, using one greatly enhances your look and the longevity of your shadow
Squeeze a small amount of the base onto the pad of your ring finger and dab it onto your eyelid.
Use your ring finger to blend the base onto your eye from the lash line all the way up to your brow bone.
Let the base dry for about 30 seconds before applying eye shadow.
• A little bit of primer goes a long way, so only use a very small amount on each eyelid. If you use too much, it can make your eye shadow crease.
• Some primers are translucent so they don't really affect the color of your eyelid, but others are available in a variety of different skin tone shades. Experiment with both and see which you prefer.
