What is the purpose of using primer in makeup?

Using primer in makeup primarily serves the purpose of prolonging makeup wear. It acts as a base layer on the skin, creating a smooth canvas that helps foundation and other makeup products adhere better. This adherence not only boosts the longevity of the makeup but also minimizes the need for touch-ups throughout the day.

Additionally, primers often contain specific ingredients that can help control oil production, reduce the appearance of pores, and smooth out the skin's texture. By optimizing the makeup's application and wear time, a primer enhances overall performance, ensuring that the makeup looks fresh and intact for longer periods.

While enhancing skin tone, lightening the color of makeup, and creating a matte finish can be aspects of certain specific products or formulations, these are not the primary purposes of a primer. The main goal is always to ensure that the makeup remains in place and looks good for as long as possible, which is crucial for achieving a polished look.
