What is the function of a primer in a makeup application?

The primary function of a primer in makeup application is to create a smooth base for makeup and prolong its wear. Primers are specially formulated products that help to fill in fine lines, improve skin texture, and create an even surface for foundation and other makeup products. This smoothing effect ensures that makeup glides on more easily and adheres better to the skin.

Additionally, using a primer can help prevent makeup from settling into pores and fine lines, ultimately enhancing the overall finish and longevity of the look. By extending the wear time of makeup, primers can help maintain a freshly applied look throughout the day, making them a crucial step in achieving a flawless makeup application.
