What is the purpose of primer in makeup application?

The primary purpose of primer in makeup application is to create a smooth base for makeup. This step is essential for achieving a flawless foundation look, as a quality primer can help to fill in fine lines, pores, and uneven texture on the skin. By smoothing out these imperfections, primer allows the subsequent layers of makeup, such as foundation and concealer, to apply more evenly and adhere better to the skin.

Using a primer not only enhances the overall finish of the makeup but also extends its wear time, helping to keep everything in place throughout the day. While certain primers may also provide additional benefits like hydration or skin tone enhancement, the fundamental role they play in makeup application is providing a smooth, even surface, ensuring that the makeup can be applied seamlessly and looks its best.
