What is the purpose of using a primer in makeup application?

Using a primer in makeup application serves multiple functions, but its primary purpose is to create a smooth base and extend the wear of makeup. A primer helps to fill in fine lines and pores, creating an even surface for subsequent makeup products. This allows foundation and other cosmetics to adhere better to the skin, leading to a longer-lasting finish.

By providing this smooth canvas, the primer can enhance the overall appearance of the makeup, making it look more polished and professional. Additionally, the formulation of certain primers can also provide added benefits, such as oil control or hydration, which contributes to the overall effectiveness in prolonging the makeup's wear. This is why selecting a primer that suits specific skin types and conditions is essential for achieving the desired makeup look.
