What is the purpose of a primer in makeup application?

The purpose of a primer in makeup application primarily revolves around creating a smooth, even base for foundation. This smooth base allows foundation to glide on more easily, ensuring a more flawless finish. A well-chosen primer can fill in fine lines, pores, and imperfections, enhancing the overall texture of the skin and improving the application of subsequent products.

While a primer can also help extend the wear time of makeup and may provide moisture depending on its formulation, the fundamental role of a primer is to prepare the skin's surface for foundation application. This foundational aspect contributes to achieving a polished and professional look in makeup artistry.
