What is the purpose of a primer in makeup application?

The purpose of a primer in makeup application is to create a smooth base for foundation. Primers are specifically designed to fill in fine lines, pores, and other imperfections on the skin, which helps foundation to adhere better and apply more evenly. This preparation step allows for a flawless finish, as it minimizes the appearance of texture and can enhance the longevity of the makeup.

While primers can sometimes enhance color vibrancy or provide hydration, these are not their primary functions. Similarly, setting the makeup is typically a task for other products, like setting sprays or powders, rather than the primer itself. Thus, the role of a primer as a foundational product that preps the skin for further makeup application is crucial for achieving a polished look.
