In makeup application, what is the purpose of primer?

The purpose of primer in makeup application is primarily to create a smooth base for foundation application. Using a primer helps to fill in fine lines and pores, leading to a more even skin texture. This allows the foundation to glide on smoothly and adhere better to the skin, enhancing the overall finish and appearance of the makeup.

While there are other products designed for covering blemishes, setting makeup, or controlling oil, primer specifically addresses the need for a uniform surface that prepares the skin before foundation is applied. Its formulation often includes hydrating ingredients or mattifying properties, depending on the desired effect, but its main function remains to provide that essential foundation for further makeup layers.
