What is the role of a primer in makeup application?

The role of a primer in makeup application is primarily to create a smooth base and prolong the wear of makeup. When applied before foundation and other makeup products, a primer can help to fill in pores and fine lines, resulting in a more even surface for foundation application. This smoothing effect not only enhances the overall appearance of the makeup, making it look more polished, but it also helps the makeup adhere better to the skin.

Furthermore, primers often contain ingredients that can help control oil production or add hydration, depending on the skin's needs, which contributes to the longevity of the makeup throughout the day. By preparing the skin properly, primers ensure that the makeup looks fresh and lasts longer without fading or settling into fine lines. This functionality of a primer is essential for achieving a flawless makeup look that endures over time, making it an indispensable step in many makeup routines.
