What is the function of a primer in makeup application?

The function of a primer in makeup application is fundamentally to prepare the skin for foundation. Primers create a smooth canvas on the skin, which allows foundation to apply more evenly and last longer throughout the day. They often contain ingredients that can help to minimize the appearance of pores, fine lines, and other imperfections, ensuring that foundation adheres better to the skin. In addition, primers can also help to control oil and shine, which is beneficial for achieving a flawless look.

While there are other steps in the makeup routine that serve different purposes—such as adding color or providing sun protection—these are not the primary functions of a primer. Makeup removers are specifically designed to clean the skin after application, so they have no relation to the pre-application process that primers serve. Understanding the role of primer is essential for creating a polished and professional makeup result.
