What is the key benefit of using a primer before applying makeup?

Using a primer before applying makeup is primarily beneficial because it creates a smooth canvas for makeup application. This smooth base allows foundation and other products to glide on more easily, promoting an even finish. The consistency of the primer helps to fill in fine lines, texture, and imperfections in the skin, which enhances the overall appearance of the makeup. This fundamental purpose of a primer is crucial for achieving a polished and professional look.

While the other options do touch on benefits that can be associated with certain types of primers, their primary function remains centered around creating that ideal surface. For instance, some primers might help makeup last longer or hydrate the skin, but those are additional benefits rather than the main purpose of using a primer. The smoothness it provides is essential for enhancing how the makeup adheres and looks once applied.
