3. To Intensify Color
Eye shadow primer can make pigment stand out and look more vibrant. Some shadows, especially powder formulas, appear lighter than they look in the palette. This is often a problem on deep skin tones. Primer can help you achieve more color.
Primer is useful in hot, humid weather to keep eye shadow from fading or smudging. It also helps prevent creasing from normal eye movements.
