Primer is one of the best-kept secrets of makeup artists, a wonder product acts as a base that maximizes the staying power of your makeup. It normally comes in two kinds: eyeshadow and face primers. Eyeshadow primer helps the pigments become more vivid and prevents your shadow and eyeliner from moving around. Face primer acts as a thin veil that diffuses pores and lines, controls oil, and reinforces the staying power of your foundation, blush, highlighter, and bronzer.
