What type of product is typically used to prep skin before makeup application?

Using a primer is essential for preparing the skin before applying makeup because it creates a smooth, even base for makeup to adhere to. Primers often contain ingredients that can help reduce the appearance of pores, fine lines, and uneven texture, which enhances the overall finish of the makeup. Additionally, primers can help makeup last longer throughout the day by providing a barrier between the skin and the makeup.

Moisturizers are important for hydration and skin care but do not specifically prepare the skin for makeup application in the same way a primer does. Exfoliators are used to remove dead skin cells, promoting smoother skin, but they don't offer the specific benefits of increasing makeup longevity or creating a base for application. Foundation is a makeup product designed to provide coverage and an even skin tone, rather than prep the skin prior to makeup application.

Overall, using a primer is the most effective way to ensure that the makeup applies smoothly and lasts longer, making it the ideal choice for prepping the skin.
