Foundation is a base makeup product that helps create an even skin tone and hides minor imperfections.
It covers spots, redness, and uneven patches, providing a smooth canvas for the rest of the makeup.
It does not remove dead cells — that’s the job of exfoliators and scrubs.
Shading effects are achieved with contour products, not foundation alone.
While foundation can add a subtle glow if it has a dewy finish, its main role is to provide a smooth and uniform complexion.
Therefore, the correct answer is Achieve smooth and even complexion.
